The 031-316-RFX: The bayonet lock provides quick mate/unmate with a positive mechanical retention, while the right-angle, free-hanging body allows routing in tight enclosures where a straight plug would not fit.
This plug terminates cables in the group RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174 — all small-diameter, 50 Ohm coax types commonly used in patch cords and jumpers. Shield termination is crimp, and the centre contact also crimps, which is the standard field-install method for these cable types. The dielectric is polyoxymethylene (POM) acetal, a rigid, low-loss material that maintains consistent impedance through the interface.
