The S series relay was developed for the
high voltage ATE market, where printed
circuit board space is at a premium.
The S series high voltage relay offers a 3kV
or 5kV* isolation performance in a 30mm
package.
Low contact resistance, through the use of
Rhodium contact reed switches, makes the
S series suitable for many high voltage
applications at DC and low frequency,
where performance and reliability are
paramount.
