What This BNC Kit Covers
The Amphenol RF 031-2201 is a complete BNC jack kit for panel-mount installations where a weatherproof seal and broad cable compatibility are needed. The kit includes the jack body, a braid clamp, a clamp, a crimp or solder contact, a panel gasket, and a washer — six pieces total, one per bag. The 500 V voltage rating and weatherproof ingress protection mean it can live on an outdoor panel or in a damp enclosure without the connection degrading. Cable compatibility covers the common RG-58 variants (58, 58A, 58B, 58C), RG-141, RG-303, LMR-195, and Belden B7806A and 9907 — a wide enough net that this one kit handles most thin 50 Ohm coax runs in a facility.
The contact termination accepts either crimp or solder — the kit ships with a contact that can be crimped onto the centre conductor or soldered, depending on your shop preference. The braid clamp and clamp handle the shield termination, pulling the braid tight against the body for a low-impedance ground path. The listed cable groups — RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907 — all share a similar dielectric diameter and braid lay, so the clamp engages consistently. If you are using a cable outside that list, check the outer jacket diameter against the clamp range in the product drawing.
Materials and Environment
The body is machined brass with a nickel finish — corrosion-resistant for outdoor or industrial cabinet use. The weatherproof rating means the panel gasket seals the interface when the flange is bolted down — not a submersible IP68 seal, but enough to keep rain splash and condensation out of the enclosure.
