Looking for additional information on reed relay technology?
Pickering has published an educational book, the Reed RelayMate, which
provides an overview of how reed relays work, how they are constructed and how to interpret their specifications and make best use of them in their applications.

Contents include:

  • Reed relay basics
  • Comparing reed relays with other relay technologies
  • Packaging reed relays
  • Manufacturing test of reed relays
  • Choosing a reed relay
  • Placing and driving a reed relay coil
  • Loading reed relays

About Pickering Electronics

Pickering Electronics was formed over 50 years ago to design and manufacture high quality reed relays, intended principally for use in Instrumentation and Test equipment. Today, Pickering’s Single-in-Line (SIL/SIP) range is by far the most developed in the relay industry with devices 25% the size of many competitors. These small SIL/SIP reed relays are sold in high volumes to large ATE and Semiconductor companies throughout the world.

Pickering Electronics is part of the privately-owned Pickering Group; made up of three electronics manufacturers, including Pickering Interfaces who design and manufacture modular signal switching and simulation products, and Pickering Connect who design and manufacture cables and connectors.

Have you ever considered the importance of reed switch blade alignment to ensure long life and optimum performance when using reed relays? We have created a short video explaining how crucial blade alignment is within a reed relay.

Correct alignment of the blades is key to ensure when they are operating, the maximum contact area comes together giving the lowest contact resistance and best contact resistance stability.

Reed Relay Selection Made Simple

Our Reed Relay Selector Tool will help you narrow down our large offering by filtering by coil voltage, switching current, contact configuration, and many more specifications. Once you narrow your selections down you can view the datasheet for more information, purchase in-stock items, or request a quote to find out lead times of made to order relays.

This short video highlights the key features of the miniature Series 104 reed relays for up to 4kV stand-off. The Series 104 has remained a firm favorite for high voltage testing for many years and now Pickering is offering up to 4kV stand-off whilst still stacking on a 0.25” pitch.


Improved performance, increase in equipment specification, and high voltage isolation protection margin are just some of the benefits of the new Series 104 4kV relays.

Pickering Electronics has increased the stand-off voltage values for its prevalent small-size Series 104 high voltage reed relays for up to 4kV. For the newly introduced versions, this means a 1000VDC stand-off voltage improvement on the previous Series 104 product offering.

Commented Kevin Mallett, Technical Specialist at Pickering Electronics: “The higher stand-off voltage improves the performance of the relay and allows for an increase in the equipment specification.” “It also means an increased high voltage protection margin for extra safety and security,” he added.
