Product details

50 Ohm BNC Plug for RG-55/142/223/400 — 4 GHz Rated

The 031-4326: It is a field-installable, crimp-terminated connector that mates with standard BNC jacks. The gold-plated center contact and PTFE dielectric maintain consistent impedance up to 4 GHz, with insertion loss specified at 0.2 dB. The bayonet lock provides quick connect/disconnect with positive retention.

This connector is crimped onto the center contact and shield, and accepts cable groups RG-55, 142, 223, and 400. Shield termination is crimp, which gives a reliable 360° ground connection. The brass body with silver finish offers good conductivity and corrosion resistance.
