Product details

50 Ohm BNC Jack for Board-Edge RF Launch

The 31-5640-1010: The 1 GHz bandwidth covers standard video, baseband data, and instrumentation links; the 0.2 dB insertion loss at that frequency keeps the signal clean for short cable runs.

Board Lock and Right-Angle Mount — What That Means for Assembly

The 31-5431 is the closest functional peer — same BNC jack, 50 Ohm, 1 GHz, 500 cycles, gold centre contact, and zinc die-cast body. The difference is the mounting feature: 31-5431 uses a bulkhead front-side nut with isolated mounting (board guide, isolated) but no board lock. The 031-5538-10RFX adds board lock and includes three pieces (connector, lockwasher, nut) but comes in a black/silver housing.
