High voltage, long life dry reed relays are rated to 200W
Despite its small, single in line format, the Series 67 range of high voltage relays are rated up to 200W. They are available from Pickering Electronics.
The 200W relays have a stand-off voltage of up to 8kV and are capable of 6kV switching. Constructed using a leadframe single in line (SIL) format, they feature former-less coils which results in a smaller package than is usual for this type of device.
“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,” explained Kevin Mallett, technical specialist at Pickering Electronics.
“The unusual SIL package style permits some interesting stacking possibilities making the relays very versatile when used to construct high-density multiplexers or matrices,” he added.
The 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 5.0, 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. Pickering can also supply can variations in the lead length of the Series 68 type on request.
The Series 67 dry reed relays are suitable for high voltage applications including electrosolar and cable testing.
Pickering offers over 1,000 standard catalogue reed relays, offers bespoke versions on many standard build options, all the way to a fully customised part, depending on requirements. For example, if a customer requests the 200W Series 67 with a different footprint or specific coil voltages or resistance figures, the company works with the designer to the meet exact specification request.
