Comparing EMRs with Reed Relays

Electromechanical relays may be adequate, but are they the ideal solution for switching in your application? In many cases reed relays offer superior performance and higher reliability whilst saving space on your circuit boards. Continue reading for more differences and see if reed relays can enhance your designs.

1. Enhanced Reliability

Unlike electromechanical relays (EMRs) with moving parts prone to wear and tear, our reed relays feature a simple, sealed construction, ensuring unparalleled reliability and longevity. EMRs are frequently contained within plastic casings, providing a degree of safeguarding. However, with time, the relay contacts can become susceptible to external contaminants, emissions from the plastic enclosure, as well as penetration of oxygen and sulfur, leading to degradation. Oxygen in particular can be an issue due to contact oxidation, which can result in degradation in low signal level switching performance.

The lifespan of a reed relay is typically 10-100 times that of an EMR. Say goodbye to frequent maintenance and downtime, say hello to reliability.

2. Faster Switching Speeds

Experience lightning-fast response times. The inherent smaller design of reed relays allows for rapid switching, outperforming EMRs and meeting the demands of high-speed applications such as test equipment and those in aerospace and defense, for example. Due to Pickering’s focus on miniaturization, our relays operate particularly fast compared to industry standards. Even our largest relays operate at less than 3ms, whilst our smallest parts operate as fast as 0.08ms.

3. Compact Size, Big Impact:

Size matters, especially in space-constrained applications. Our reed relays boast a compact form factor, offering superior packing density without compromising on performance. Our range of high power reed relays rival the power specifications of electromechanical relays, whilst enjoying all the benefits that Pickering has to offer.

4. Low Power Consumption:

Bid farewell to unnecessary power drain with our reed relays. Unlike EMRs, which may consume more power, our reed relays are designed for efficiency, ensuring optimal performance while minimizing energy costs—a win-win for your applications.

5. Superior Performance in Harsh Environments:

When it comes to durability, our reed relays are second to none. Built to withstand extreme temperatures, high vibration environments, and other challenging conditions, they outperform EMRs, delivering consistent performance and reliability where others may falter.
