Pickering Electronics, a global provider of high-performance reed relays, has introduced a new 20kV addition to its long-established high voltage Series 63 range.
The company claims that the latest addition sets a new industry standard by offering 20kV stand-off across the switch contacts – a first-of-its-kind capability that Pickering says no other relay manufacturer currently offers. The new 20kV high voltage reed relay was unveiled at electronica China 2025, taking place in Shanghai, China from 15-17 April 2025.
The new relay is designed for demanding high-voltage applications, featuring up to 20kV stand-off and 12.5kV switching at a maximum of 50W. Tungsten-plated contacts ensure a long and reliable life, supporting up to 100 million operations when cold switching. Ideal for a variety of high-voltage testing and switching applications, including hi-pot testers, high-end cable testers, electric vehicle (EV) charge point testing, solar energy systems, medical equipment and high voltage instrumentation, Series 63 is also available with fast lead times of three to four weeks for orders of up to 200 pieces, and five to six weeks for larger quantities.
“We’re excited to introduce this new high voltage addition to our Series 63 range at electronica China,” says Robert King, Reed Relay Product Manager at Pickering Electronics. “The 20kV stand-off capability across the switch contacts is a game changer for industries requiring robust, reliable, and compact high voltage switching solutions. With its enhanced performance and short lead times, this relay is ideal for customers seeking both efficiency and innovation.”
The Series 63 20kV reed relay offers exceptional performance and flexibility for a wide range of high voltage applications, with key features including compact PCB mounting with push-on HV connections on the top face, supplied with appropriate connectors and insulating boots. Both Form A (energise-to-make) and Form B (energise-to-break) configurations are available, with 24V coils, and it is usually possible to achieve a Form C (change-over) function by using a Form A and a Form B type together.
An internal mu-metal magnetic screen allows Form A versions to be mounted side by side without interference, and an optional electrostatic screen and/or earth connection to the magnetic screen offers enhanced EMC protection. Maximum switch current is 3 Amps, with maximum carry current of 3.5 Amps.
In the year that Pickering celebrates more than half a century of expertise in high voltage reed relay technology, and the launch of its new Centre of Excellence for high voltage switching, the company says that this new relay reflects its ongoing commitment to innovative product improvement, driven by customer requirements and engineering excellence.
