Pickering introduces 20V relay to Series 63 range

This latest addition from Pickering sets a new industry standard by offering 20kV stand-off across the switch contacts – a first-of-its-kind capability that no other relay manufacturer currently offers, according to the company. The new 20kV high voltage reed relay was unveiled at electronica China 2025, taking place in Shanghai, China from 15-17 April.

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.

Well suited 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 3-4 weeks for orders of up to 200 pieces, and 5-6 weeks for larger quantities.

“We’re excited to introduce this new high voltage addition to our Series 63 range at electronica China,” said Robert King, Reed Relay Product Manager, 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 delivers 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 same 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, this new relay reflects the company’s ongoing dedication to innovative product improvement, driven by customer requirements and engineering excellence.
