Panel-Mount BNC Jack for RF and Instrumentation
The 1-1337446-0: This connector is part of the Greenpar series, built for reliable RF signal transmission up to 2 GHz. The silver-plated brass body and silver-plated phosphor bronze centre contact, combined with a PTFE dielectric, provide stable impedance and corrosion resistance in indoor and outdoor environments. Typical uses include test equipment, telecom infrastructure, and instrumentation where a bayonet-coupled BNC interface is required.
Frequency and Impedance Performance
Above 2 GHz, the VSWR rises beyond the BNC interface's typical specification, so this connector is best kept within its rated band.
Mechanical and Environmental Ratings
The bayonet lock provides quick connect and disconnect with a positive coupling indicator — the slot-and-pin engagement is audible and tactile. The silver body finish is standard for BNC connectors in indoor environments; for corrosive atmospheres, a gold-plated variant may be preferred.
Termination is solder cup for the centre contact and solder for the shield — a straightforward hand-solder operation for cable assembly. The panel mount uses a flange with two mounting holes; the connector body is brass with silver plating. The shield termination is soldered directly to the cable braid, providing a low-impedance ground path. The extended insulation feature (listed in the spec) adds creepage distance between centre contact and body, useful for higher-voltage applications within the 500 V rating.
