The D1 series is a reed relay with
changeover contacts which are often used
in safety critical applications.
These are PCB mount relays, though
custom options may be available on
request.
The switching is achieved through the use
of high vacuum reed switches with
Tungsten contacts and make these relays
suitable for high reliability applications,
such as test equipment and high voltage
power supplies.
