Details
The 123-RG316NFSB is a Bulkhead N-Type Female Straight connector for RG-316 cable, with solder termination.
Threaded coupling with a defined torque specification ensures repeatable VSWR and reliable mechanical retention under vibration and thermal cycling.
Bulkhead-mount construction — the connector body passes through a chassis wall with a threaded nut securing it to the panel from the back side. Designed to maintain mating geometry and RF performance while transferring mechanical load to the chassis rather than the cable. Ideal for antenna pass-throughs, equipment enclosures, and field termination boxes where the connector face must present cleanly through a panel.
