Reed switches with sputtered ruthenium contacts for Pickering Electronics for low level ‘dry’ switching

UK reed relay maker Pickering Electronics has launched a high power SIL/SIP reed relay rated for 1A switching at up to 40W and up to 3A continuous carry current.

The Series 100 HC instrumentation-grade switches use sputtered ruthenium contacts for low level or ‘dry’ switching applications.

“The Series 100HC offers over double the coil resistance of other similar products and the continuous carry current specification of 3 Amps can be increased in pulsed current applications,” said Kevin Mallett, Technical Specialist at Pickering Electronics. “The higher coil resistance also results in reduced heating giving Series HC reed relays a thermal EMF performance less than 10μV.”

Series 100 HC high power SIL/SIP reed relays feature an internal mu-metal screen to minimize issues that would otherwise be experienced due to magnetic interaction when they are closely stacked. Devices are available with 5, 12 or 24V coils with optional internal diode and with one or two switches in a single package.

 The new high power SIL/SIP reed relays are suitable for high power applications, and in many cases may be used as an alternative to mercury wetted reed relays.
