D series
high voltage reed relays
15kV, 50W

The D series is capable of withstanding voltages
up to 15kV, the D series high voltage reed relay issuitable for high reliability applications such as
cardiac defibrillators, test equipment and highvoltage power supplies. Two contact materials
are available for low contact resistance or powerswitching applications. Standard coil voltages of5, 12 and 24 volts are available with form A and
B contact configurations.

# 15kV Isolation# Low Contact Resistance# High Power Switching# PCB or Panel Mount# Flying Lead, Solder Turret andFaston* style spade terminals Options

Printed Circuit Board (PCB) mount and panel
mount (nylon studs) configurations available.
Optional electrical connections include solder
turret tag, flying lead and Faston* style spadeterminals.
