50 Ohm BNC jack, panel-mount, for 1.5D-2V cable
The Hirose BNC-PJ-1.5DV-1(40) is a 50 Ohm BNC jack — female socket, single-port, panel-mount with a bayonet lock. It's built for the 1.5D-2V cable group, which means the clamp-style shield termination and the dielectric are sized for that specific coax diameter and dielectric type. The center contact is silver-plated beryllium copper, a combination that gives you good conductivity and spring memory through repeated mates. Rated to 1 GHz max frequency, this jack sits in the standard BNC impedance-controlled family; the 50 Ohm match is the one you want for RF test equipment, telecom base station gear, or any signal chain where the characteristic impedance has to hold through the interconnect.
500-cycle mating life, silver contact
Rated for 500 mating cycles — that's a solid number for a BNC in a patch panel or a test-lab wall plate where the cable gets swapped regularly. The silver plating on the beryllium copper center contact handles the wear; silver is softer than gold but in a BNC the wiping action of the bayonet lock keeps the contact surfaces clean. The body is nickel-plated brass, the dielectric is PTFE — the same material that gives you stable impedance across temperature and frequency. Operating range is -30°C to 60°C, which covers indoor equipment rooms and most outdoor enclosures that aren't in direct sun.
Panel-mount with flange, clamp shield termination
Mounts through a panel cutout with a flange — the bayonet lock nut tightens from the front, the flange sits against the panel. The shield termination is a clamp, not a solder bucket: you strip the coax braid, slide it under the clamp ring, and tighten. That saves time on the assembly bench and gives a more repeatable shield bond than soldering braid to a ferrule. The center conductor solders into the contact. The whole assembly is keyed by the BNC interface itself — no extra alignment pins, the bayonet slot and the two slots in the jack body set the orientation.
