Very high isolation voltages, up to 15kV, are

achieved through the use of high vacuum reed

switches with either Rhodium or Tungsten contacts

and make these relays suitable for high reliability

applications such as cardiac defibrillators, test

equipment and high voltage power supplies.

The Rhodium contacts have low contact resistance

while the Tungsten contacts can switch higher

voltages.

Printed Circuit Board (PCB) or Panel mount, via

nylon studs, versions are available.

Connection options include PCB, solder turret tag,

flying lead and Faston* style Spade Terminals.

Available as Form A (SPNO) or Form B (SPNC)

contact configurations.
