Spec Sheet

  • These new, unused Jennings quality RF rated latching vacuum relays (10 kV test!) have an outstanding 60 hz continuous current handling capability of 50 Amps!
  • The latching feature provides two momentary duty coils. Pulse one coil to latch contacts in closed position, and pulse other coil to latch contacts in open position. No need to keep power to coils to keep contacts in desired position, once selected. Can easily be controlled with three wires.tie (-) together, and by means of momentary pushbutton switches, briefly supply + 24 to 30 VDC to the desired “+” coil to open or close contacts. A small ½ amp supply should be plenty.
  • Each of the two contacts provides two oversized (0.4 inch wide!) tinned tabs, allowing leads to be connected to both sides if desired to divide current between multiple smaller leads.
