A - SMA signal connectors (only on contact types 10, 25, 27 & 65) F - F-Type signal connectors (only on contact types 10, 27) T - TNC signal connectors (only on contact types 10, 25, & 65) I - Insulated coaxial shield (only on contact types 10, 25, 27 & 70) S - Insulated & switched coaxial shield (only contact types 10, 25, 27, 70) L - Lockscrews on control connector so mate can be secured


U70000 NOTES:


1. The I or S options are not available on the optional signal connectors or the contact type 90 (triaxial).


2. The “expander” port is not available any longer. 3. No mating connectors or hardware are included. 4. Contact type 70 must be mounted with signal connectors facing up. 5. Due to new environmental laws, USC may or may not be able to sell relays with mercury wetted contacts. Spec was 2A, 50W. Connectors must be within 20 deg of up. 6. For installing into the U11600 chassis, the “-1” coil voltage is needed. 7. Type 27 and 67 use the standard 50 ohm MSC connector.


URS70000 NOTES:


1. The I or S options are not available on the optional signal connectors or the contact type 90 (triaxial).


2. The “expander” port is not available any longer. 3. No mating connectors or hardware are included. 4. Contact type 70 must be mounted with signal connectors facing up. 5. Due to new environmental laws, USC may or may not be able to sell relays with mercury wetted contacts. Spec used to be 2A, 50W. 7. Type 27 and 67 use the standard 50 ohm MSC connector.
