Industry-first 20kV stand-off relay sets new standard for high voltage switching

Pickering Electronics has introduced a new 20kV addition to its established high-voltage Series 63 range. This latest addition sets a new industry standard by providing a 20kV stand-off across the switch contacts – a first-of-its-kind capability that no other relay manufacturer currently offers.

The new relay is created for demanding high-voltage applications, providing up to 20kV stand-off and 12.5kV switching at a maximum of 50W. Tungsten-plated contacts assure a long and reliable life, supporting up to 100 million operations when cold switching. Ideal for various high-voltage testing and switching applications, including hi-pot testers, high-end cable testers, EV charge point testing, solar energy systems, medical equipment and high-voltage instrumentation, Series 63 is also available with fast lead times.

“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 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 delivers outstanding performance and flexibility for various 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 permits 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 improved EMC protection. The maximum switch current is 3A, with a maximum carry current of 3.5A.
