The S1 Form B series is a miniature high
voltage single-in-line reed relay for
applications where space saving is a
prime consideration, with normally closed
contacts.
The coil pins are positioned near the centre
of the relay while the contact pins are near
the ends to give improved isolation
between the high voltage contacts and the
low voltage coil.
Custom versions can be designed for particular applications.
Please contact Cynergy3 with your requirements.
