Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has launched industry’s smallest high voltage relay. Housed in the miniature SIL/SIP package, new Series 131 reed relays have a footprint of just 12.5mm x 3.7mm and a height of 6.6mm and deliver a minimum stand-off of 1500V.

Featuring a  choice of 3, 5 or 12 volt coils, with optional internal diode, Series 131 reed relays are available in the 1 Form A (energize to make) SPST N.O. configuration, and can  switch up to 0.7 amps, 10 watts. Devices are ideal for cable testers, mixed signal/semiconductor testers, backplane testers, high voltage instrumentation, in-circuit test equipment or other HV applications.

Commented Keith Moore, CEO, Pickering Electronics: “Pickering Series 131 miniature SIL reed relays utilise vacuumed, sputtered ruthenium reed switches which have a superb low level performance, making them an excellent choice where a wide range of signals are involved. The range is based on our long-established Series 113 style of plastic package that incorporates an internal mu-metal magnetic screen to enable high packing density, and Pickering’s SoftCenter® construction which protects the reed switch.”

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 of companies; 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.

Technical Support Engineer

Job Title: Technical Support Engineer

Job Type: Full-time, Permanent

Start date: ASAP

Pickering Electronics is a world leader in the design, manufacture and distribution of Reed Relays, with its headquarters based in Clacton on Sea, Essex.

We are currently seeking a full time Technical Support Engineer to join our busy and expanding Engineering Team.

Reporting to the board you will be the clear point of contact for all technical enquires from global customers and procurement/application Engineers. As part of the Engineering team your primary objective will be to support the sales and engineering department on all matters relating to the function of existing or proposed products; so that the company’s reed relay product range can be competitively marketed to maximum commercial advantage.

Regular international travel will be required with this role.


Pickering Electronics has extended its 4mm product family with the Series 122 reed relay.

Used in high speed test systems, occupying a PCB footprint of 4x4mm, Pickering claims the relay provides the highest packing density currently available. The relay measures 12.5m

m in height and can operate from 3V or 5V. Its contacts are rated with a switching current of 0.5A at 10W.

Featuring instrumentation-grade sputtered-ruthenium switches, the 1 form A (SPST) normally open energize-to-make devices have plastic packages with internal mu-metal magnetic screening to avoid cross-interference and ‘false’ switching in densely packed applications.

Devices are tested for dynamic contact resistance and have an insulation resistance of greater than 10¹²Ω.

The relays may be socketed using SMD or through-hole sockets. However, care must be taken to mitigate the risk of affecting contact resistance integrity.

The Series 122 reed relay is suitable for test systems such as A.T.E. switching matrices or multiplexers, Pickering says.

Keith Moore, CEO at Pickering Electronics says “We launched our first 4mm2TM product, the Series 120, with a switching rating of up to 1A at 20W and a height of 15.5mm. Last year, the Series 124 reduced this profile to 9.5mm but with a slightly lower rating of 0.5A at 5W. We can now provide customers with the new Series 122 device which fills the gap in our product range and offers the flexibility required to design in a product that exactly matches their requirements.”

Pickering will be showing the Series 122 relays at Productronica in Munich, 12-15 November.
