New high-voltage, long-life dry reed relays now rated up to 200W

05-05-2022 | Pickering | Power

Pickering Electronics has released another high voltage relay within the unique Series 67 range. Now available with the highest power switch in the Pickering portfolio, rated up to an impressive 200W. With a stand-off voltage of up to 8kV and capable of 6kV switching with a power rating of 200W, the relays are constructed using a leadframe in a SIL format and provide former-less coils, which results in a smaller package than is usual for this type of device.

Commented Kevin Mallett, technical specialist at Pickering Electronics: "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."

These dry reed relays feature PCB connections to switch and coil. Similarly rated sister devices in the company's Series 68 family have PCB connections to the coil, and flying leads to the switch, separating 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 provided to special orders, as can variations in the lead length of the Series 68 type.

The relays are ideal for high voltage applications, including electrosolar and cable testing. More information on the new 200W Series 67 is available here.

The company provide over a thousand standard catalogue reed relays, but for those that need something a little more bespoke, the company supplies many standard build options, all the way to a fully customised part, depending on needs. For example, if you are interested in the 200W Series 67 but need a different footprint or specific coil voltages or resistance figures, the company would be happy to work with the designer to the meet exact specification request.
