The ultimate comparison between reed switch and other switching technologies

History of the reed switching technologies in the electrical industry

The year 1936 accounts for the invention of the reed switching technology by one of the renowned team of scientists at Bell Telephone laboratories. Since the design of the reed switching technology, it has increased from large parts to small parts, which are ultra-reliable and durable for working with low power consuming electrical gadgets. The only things which have changed are the production methods and improvised quality optimization in the development of the reed switching technology. The production costs of reed switching technology have also reduced significantly. Let us overview on some of the significant differences between reed switching technology and other switching technologies.

All about the electromechanical relays Vs. the reed switching technologies

The EMR or the electromechanical relays are widely used in all the major manufacturing industries as they are too cheap and reliable for the switching functions. All the electronic production companies spend a lot on their investment to fetch the EMR or the electromechanical relay for switching purposes. We have mentioned below one some of the key differences between the electromechanical relays and the reed switching technologies

The key differences between the electromechanical relay and reed switching technology

  • The reed switching technologies work faster than the EMR as the moving parts in the reed switching technology are much simpler than the electromechanical relay.
  • The reed relays have sealed contacts, and hence they work more efficiently with the low power signals when compared to the EMR as the EMR’s have plastic packages which overtime get damaged due to pollutants and other emissions.
  • The reed relays also have longer mechanical life when compared to that of the EMR’s. The main difference in the automated life arises due to the moving parts in both EMR and the reed switching technology.
  • The reed switching technology also consumes less power than the EMR switching technology.
  • The EMR is designed in such a way that they close in a wiping structure, and hence they clean themselves. But with overtime, the contact plating starts degrading.
  • The EMR also offers low contact resistance when compared to the reed switching technology as they possess more extensive contacts, and hence they are only suitable for low resistance.
  • The EMR’s also have a higher average rating than reed switching technology as they have more extensive contacts.

The general introduction to the reed switch technology

One of the common problems which all the users of the gas and water meters face is low-power metering and position sensing, and hence the engineers have brought a smart solution for the position sensing problems. The electrical engineers are using the latest modes of technology like the magnetoresistive (MR) or the hall effect sensors, which can take care of the sensitivity, durability, and reliability of the electrical appliance.

The new innovative technology offers herds of benefits to the electrical society somewhat, but they somehow lag behind some of the best features provided by the reed switch technology. For the recent three-to-four decades, the reed switch technology has been at the top when the concern is for operating the low-power switches with battery-operated applications.

We have brought here some of the best advantages of using the reed switch technology and all the ways of customizing the reed switch for diverse applications. We will also over-look on some reasons as to why the reed switch technology is in hype across the planet. We will also sense the pivotal position of the technology and how does the reed switch technology controls the market.

All about the low-power metering demands

The gas and water meters have automatic meter systems fitted along their body, which consist of sensors which demand low power. The reading of the water and gas is measured by a magnet that is attached to a shaft present on the meter. Every single revolution of the attraction is either directly or indirectly converted into an electrical signal, which is later controlled by an embedded system.

The critical parameter design is directly proportional to the low power demands in the system. The average lifetime of all the gas and water meters is twenty years without the replacement of the batteries.

The simple customization of the reed switch technology

The reed switch technology is aesthetic, but as it offers reliability and durability to the low-power applications, it is the first choice for all the users. Generally, a reed switch is an electrical switch that is controlled by a magnetic field. The composition of the reed switch consists of three or four metal pieces called reeds, which contain plated contacts at small distances. The Reed is later enclosed inside a glass tube with inert gas.

Best comparison between the digital and thermal overload relay

What are the primary working methodologies of the overload relay?

The overload relay is an electronic device that turns OFF the motor or the heater automatically when there is an overload. The overload relay turns OFF the engine when a higher voltage is applied; this is more than the suited voltage of the motor pump. The application of the overload relay can prevent the coil inside the motor from getting burnt due to the higher voltage.

Many people are in a big misconception that it is normal for the motor pump coil to get burnt with time. Each rewind of the overload relay can cost up to 7000 – 10000 INR, and hence it is difficult to change the coil of the overload relay regularly.

The burning of the coil can easily be prevented by applying an overload relay, which can turn-OFF the motor when it senses a massive electrical voltage input than usual.

The advantages of using the overload relay

  • The overload relay can ensure that the motor is safe and runs for longer life and can also protect the engine from any potential damage.
  • The overload relay can also prevent the loss, which can occur due to the breakdown of the water pump.
  • The overload relay can protect the motor from being damaged, and hence all the people can save on their yearly budget by minimizing the cost of maintenance and repairs which they spend every year on the motor.
  • As the overload relay protects the motor from variant flaws, it is evident that it increases the life-span of the engine.

What are the major types of overload relay?

There are two types of overload relay

  1. Thermal overload relay and
  2. Digital overload relay

The thermal overload relay trip off the motor when a higher temperature is observed, which is higher than the average temperature.

The digital overload relay monitors the input voltage and current through a digital meter and hence trip off the motor when the voltage value exceeds the average value.

The thermal overload relays were a popular choice of vendors for a more extended period. The only problem with the thermal overload relay is they are climate dependent. On the other digital overload relay does not provide any room to the factors, and hence they can be considered as a good option for modern motors.

Why are hybrid relays the best for all the complications?

Why are hybrid relays the best for all the complications?

How can hybrid relays only all the complications?

The hybrid relay uses the application of the static and mechanical relay, which are also termed as an electromechanical relay (EMR) and the solid-state relay (SSR). Philosophically, the hybrid relay creates a fruitful relationship between the low voltage drop and high reliability of the silicon semiconductors. Some of the significant applications of the hybrid relay include heater set-up and motor starters in the home.

One of the most critical challenges for the entire industrialist is to control the hybrid, and hence it is not easy that it seems from the term. Due to the occurrence of the voltage spikes between the mechanical switch and the silicon switch can create some electromagnetic noise emission. We have brought some of the best techniques in the article, which can help the users of the hybrid relays in preventing the voltage spikes.

How to control the voltage-spikes in the hybrid relay?

The people who select AC switch for the solid-state relay and electromechanical relay have their positives and negatives on the side. The solid-state relay can perform the reaction at a rapid pace, and there is no voltage bounce during the ON period, and no sparks arise during the turn OFF period. The leading cause is the EMI and the shorter-relay time in the solid-state relay. The electromechanical relay can make sure that there is no conduction loss in the entire process. The electromechanical relay also prevents the heat sink for the applications over 2A RMS. The electromechanical relay also establishes an insulation terminal between the driving coil and the power terminals of the relay. The insulation between the driving coil and the power terminal make sure that it renders the SCR or the silicon controlled rectifiers.

What is zero-voltage switching?

Many experts believe the fact that switching the electromechanical relays a close to zero voltage can provide them a longer life. The electromechanical relays can also tend to live longer when the whole switching process occurs at DC or DC voltage.

The switching on at the zero-voltage also increases the in-rush current, which can decrease the capacitive loads, which includes the electrical lamps, fluorescent tubes, and inverters. The switching on at the zero-voltage can also increase the life of the capacitor and can also regulate the recurrent voltage fluctuations inside the electrical appliance.

What is the need for hybrid relay switching in the market?

Most of the people related to the electric field would have much in-depth knowledge about the two most significant types of relays which are

  1. EMR or electromechanical relay and
  2. SSR or solid-state relay

The ultimate comparison EMR Vs. SSR

Both electromechanical relay and the solid-state relay have merits and demerits on their side, but what’s more important is which among the two is best. Some people hold the bottom of SSR as it is more reliable as the electromechanical relay produces arcs and loses its reliability. On the other hand, some people say that SSR provides heat losses, and EMR is much more convenient and cheaper when compared with the SSR. The SSR also does not use any moving devices, which is the leading cause of its reliability. Both SSR and EMR can work either on AC or DC based on the situation.

The solid-state relay waste a lot of power as it drops down the voltage when the electric signals pass through the semiconductor channel. For example, the SSR can consume 15 watts or more than that for giving a 10 A of electrical load.

What are hybrid relay switching and its significant applications in the market?

By comparing the EMR and SSR, we conclude that both are good at some points and also hold an equal amount of negatives on the other. The best solution to make the best relay is creating a hybrid of EMR and SSR, which can offer both the features and hence increase the standard of the circuit.

To bring the right solution for all the problems, the Echola systems have brought PDUs types of relays, which make use of both electromechanical relay (EMR) and solid-state relay (SSR) and hence it successfully eliminates the cons of duo comprehensively.

The hybrid form of relay or PDU holds a parallel setup of the circuit of EMR and SSR. The SSR output switches the load when the signal is applied. On the other hand, the EMR establishes a parallel path for signal transport. Due to this operation, no-heat or small heat traces are produced in the SSR. As the SSR holds the initial load, the EMR does not have to transfer the entire amount, and hence the process can be completed in such a quick time.
