Loral is now Narda
Decrypting the part no from Narda data:-
132 Transfer
B Latching needs pulse of 30 to 100ms
2 Indicator Circuitry
D Type N
1 Solder((Standard)
C 24VDC
1 DC - 3 GHz
B Common Minus
! Bracket
Power Handling - Cold Switching, 25degC, Matched 50 ohm, sea level.
432 MHz 700W
1296 MHz 420W
144 MHz 1.2kW
3GHz 270W
Derating-
VSWR 1.5 .94
2.0 .88
3.0 .78
4.0 .70

> They each have 4 N connectors and I have already tested them with 24 VDC and they work fine--when voltage is applied to position 1, connectors 1-4 and 2-3 are connected. When voltage is applied to position 2, connectors 1-2 and 3-4 are connected. There are also poles for indicator lights. Physically the relays are in a 2" square cube and there is a mounting plate attached. I have tried many combinations of searching for info, but find none. Perhaps someone can direct me to a source?
