BNC P/M 4-Hole Jack, Dual Crimp Type for RG174, 188, 316, B7805A, URM95, LMR100 Cable

Applications

Features

BNC connectors with a 50 ohm nominal impedance are designed for use in telecommunication, data communication and test and instrumentation equipment. BNC connectors with a 75 ohm nominal impedance are designed for broadcast, video and other applications which require impedance matched performance. Both 50 ohm and 75 ohm BNC connectors are intermateable.
Interface according to IEC 169-8, MIL-STD-348B

Special Notice

• The specification is listed below for information. All dimensions are fully complied with Military requirements.

S-Conn provides commercial grade connectors, and environmental requirements we can test in-house is Salt
