Industry’s most customisable HV reed relay unveiled by Pickering
Pickering Electronics has introduced its most customisable range of high voltage reed relays to date The Series 600 offers more than 2500 different combinations of rating and connection options. Pickering has developed Series 600 in response to increasing demand for tailored high voltage reed relays. It employs a modular design architecture that allows engineers to precisely specify the rating parameters and connection options they require for their application, without compromising performance.
The Series 600 relays provide a 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 the industry’s highest switch-to-coil isolation, up to 25kV—ensuring 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 ideal for applications where both high voltage and high power switching are required.
Manufactured with tungsten-plated contacts for 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 contact forms can be specified to meet thermal, mechanical, or environmental constraints, and application-specific performance testing can be provided.
Series 600 relays are ideal for a wide variety of high-voltage test and switching applications, including: hi-pot testers; power and signal cable testers; EV BMS and charge point testing; inverter or insulation resistance testing in solar energy systems; isolation in medical equipment; and high voltage switching and signal control for instrumentation.
