Jennings RF5A   SPST, normally closed, ceramic vacuum relay. These compact relays are not a latching type, but do have normally closed contacts. Contact ratings are 8 kv test, 7.5 kv peak working, 12 amps maximum. Contact resistance is 20 milliohms. Coils are 26.5 vdc, pull-in voltage is 16 vdc, and drop-out voltage can vary from 1-10 vdc.  These relays are extremely FAST... same rated speed as the popular RJ1A, at 8 milliseconds operate, 8 milliseconds release! They are rated for an extremely long service life of 10,000,000 operations!

Supplied with a 3-hole aluminum flange mounting collar, which can be slipped over the top of the relays to hold the very small flange in place against the chassis. The photo shows the collar in place on the top 3 relays, and removed from the bottom two relays. A US quarter dollar coin is shown for scale. Condition is removed from equipment, fully tested, and guaranteed. May be supplied with protective capacitor and diode installed across coil, as recommended by the manufacturer.

Replacement Coils  

When a vacuum relay fails, it is of course very rare for both the removable coil and the contact set to both fail at the same time. Lightning damage is normally the only cause of simultaneous failure. The coil is easily removable by means of a screw or nut on the very bottom of most vacuum relays. This leaves the contact set (with contacts still sealed in a vacuum). The failed component can be easily replaced at well less than the cost of an entire new unit.

We have a good assortment of coils (All are 26.5 vdc coils unless specifically noted otherwise.) If you do not see the coil you want, please feel free to call or email with your needs. We frequently have additional coils that are not shown here.
