Pickering Electronics has introduced the most customisable range of high voltage reed relays to date, the Series 600, which offers more than 2,500 different combinations of rating and connection options.
Utilising over 55 years of experience in the field, Pickering has developed Series 600 in response to growing demand for tailored high voltage reed relays. It employs a modular design architecture that enables engineers to precisely specify the rating parameters and connection options they need for their application without compromising on performance.
“We’ve been manufacturing high-voltage reed relays for more than 55 years,” said Robert King, Reed Relays Product Manager, Pickering Electronics. “While our catalogue relays meet most general needs, applications above 5,000 volts, or those with unique constraints, often demand something more specialized. Series 600 answers that call, giving engineers the flexibility to fine-tune key specifications while maintaining the proven reliability of Pickering’s core technology.”
The Series 600 relays deliver a versatile solution for a wide range of high voltage application requirements, switching from 3.5kV up to 12.5kV, with standoff voltages from 5kV to 20kV, and one of the industry’s highest switch-to-coil isolation, up to 25kV—ensuring reliable isolation for control circuitry from high-voltage paths, even in demanding environments. With switching power capabilities up to 200W, Series 600 relays can safely handle higher energy loads, making them well suited for applications where both high voltage and high power switching are required.
Manufactured with tungsten-plated contacts for superior reliability and operating life, Series 600 relays also feature internal mu-metal magnetic screens, which minimise magnetic interference (reducing magnetic interaction between adjacent components from 40% down to less than 5%) and promote relay stability, allowing Form A (energise-to-make) versions to be mounted side by side—ideal for dense PCB layouts. Insulation resistance is over 10¹³ Ω, ensuring minimal leakage and maximum isolation for applications requiring high reliability.
Further flexibility is available through the inclusion of coaxial or electrostatic screens for improved signal integrity and noise reduction, as well as optional diodes or Zener diodes for managing coil back EMF. A wide range of case sizes, potting materials, and contaforms ct can be specified to meet thermal, mechanical, or environmental constraints, and application-specific performance testing can be provided.
