Product details

N-Type Plug for RG-401 Semi-Rigid Line — 50 Ohm to 11 GHz

This plug is built for RG-401 (.250" semi-rigid) cable — the body dimensions and centre-contact bore match that cable diameter. Termination is crimp or solder for the centre contact; shield termination is solder. The package includes the connector body and one contact, so you have everything to terminate one cable end.

Brass body with white bronze finish, silver housing colour. Threaded fastening gives a vibration-resistant mate that won't back off under cable flex.
