F Type Jack for 75 Ohm Video/Broadband Systems
The 5-1814826-1: It accepts RG-59B, 62A, 140, and 210 cable groups, which covers the common 75 Ohm coax types for residential and commercial broadband drops.
Panel Mount with Bulkhead Front-Side Nut
The threaded fastening type keeps the mating plug from backing off under vibration, though in a fixed installation the nut torque is the only thing holding the pair together.
2 GHz Bandwidth and 500 V Rating
Rated to 2 GHz maximum frequency. The center contact is tin-plated brass.
The 5-1814826-1 is listed as Obsolete. If the design can tolerate a parametric alternative, a current-production F Type jack from the same cable group and impedance range would be the practical replacement, but no direct cross-reference is documented here.
