Product details

Mini BNC plug for RG-179 — 75 Ohm, crimp termination

It ships as a three-piece kit — connector body, centre contact, and crimp ferrule — ready for field termination.

Obsolete — sourcing through independent distribution

No official replacement order code is on record.

Crimp termination for RG-179 — field-fit checklist

The shield termination is crimp, not solder or clamp — the ferrule compresses the braid against the cable jacket for a gas-tight connection. The bayonet lock mates with any standard mini BNC jack; the 75 Ohm impedance holds only when the cable is RG-179 or a 75 Ohm equivalent with the same dielectric diameter.

500-cycle mating duty — field-service reconnect

The 500-cycle rating means this plug survives repeated mate/unmate cycles in test equipment, patch panels, or field-service connections where the cable gets disconnected and reconnected regularly. The gold-plated centre contact resists oxidation and fretting corrosion through those cycles. Silver housing colour is cosmetic — the nickel body finish provides the environmental seal.

Frequently asked questions

Where can I buy 1274563-3 and what is the price?

The 1274563-3 is obsolete and sourced through independent distribution against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for your quantity.

What cable does 1274563-3 fit?

The 1274563-3 is designed for RG-179 coaxial cable. The kit includes the connector body, centre contact, and crimp ferule sized for RG-179.

What is the impedance of 1274563-3?

75 Ohm. The PTFE dielectric maintains the 75 Ohm impedance through the connector-to-cable transition.
