High-voltage, long-life dry reed relays rated up to 200W

Pickering Electronics has released another high voltage relay within the Series 67 range, rated up to 200W, with a stand-off voltage of up to 8 kV, and capable of 6kV switching.

Series 67 relays are constructed using a leadframe in a Single-in-Line (SIL) format and feature former-less coils which results in a smaller package than is usual for this type of device.

Kevin Mallett, technical specialist at Pickering Electronics, commented: “Long-life tungsten contacts with a higher power and high current carry capabilities enable Series 67 reed relays to be used in high-performance applications where high reliability is demanded. The unusual SIL package style permits some interesting stacking possibilities making the relays very versatile when used to construct high-density multiplexers or matrices.”

Series 67 dry reed relays feature PCB connections to both switch and coil. Similarly rated sister devices in Pickering's Series 68 family have PCB connections to the coil and flying leads to the switch which separates the high voltage away from the PCB. Devices are available with 5, 12, and 24V coils with optional internal diode, and in 1 Form A and 1 Form C configurations. Other voltages can be supplied to special orders as can variations in the lead length of the Series 68 type. The Series 67 dry reed relays suit high voltage applications including electrosolar and cable testing.

Pickering offers over a thousand standard catalogue reed relays, but for those that require something a little more bespoke, the company offers many standard build options, all the way to a fully customised part, depending on requirements.
