SHV Plug for High-Voltage Coax — 5000 V, Bayonet Lock, RG-58
The TE Connectivity 5051426-4 is a Coaxicon-series SHV plug designed for high-voltage coaxial interconnects. It is a female socket connector with a bayonet lock, rated for 5000 V, and built for RG-58A and RG-58C cable. The connector ships as a kit — 3 pieces: the connector body, a gold-plated center contact, and a ferrule. The center contact is gold-plated for stable contact resistance over the rated 500 mating cycles, and both the shield and contact terminate via crimp. The silver body finish provides a low-resistance shield path.
What the 5000 V Rating Means for Your Application
The 5000 V rating is the defining spec of this SHV connector — it is not a standard BNC or UHF connector. The PTFE dielectric and the bayonet lock are sized to maintain the creepage and clearance needed for that voltage. The non-constant impedance means this is a power-delivery connector, not a precision RF signal path; use it for DC or low-frequency high-voltage connections where the impedance match is not critical.
Mating and Termination — Field-Ready Kit
The bayonet lock mates quickly and holds under vibration — a standard SHV interface. The connector is free-hanging (in-line), so it is intended for cable assembly, not panel mounting.
