It belongs to the SMP series, a push-on (snap-on) connector family that saves panel space compared to threaded SMA or BNC types. This specific variant is a kit that includes the connector body, end cap, ferrule, and insulator — four pieces total — so you get everything needed to terminate one cable end in one order line. The snap-on fastening type provides quick connect-disconnect without tools — useful for field-replaceable modules or test points — but the 100-cycle mating rating means it is designed for moderate reconnect duty, not daily production test cycling.
Cable Group and Termination Details
This SMP plug is built for the RD-316 cable group, which covers RG-316/U and equivalent 50 Ohm coax with a 0.102-inch (2.6 mm) dielectric diameter. The dielectric material is PTFE, which maintains stable impedance and low loss up to the rated frequency. Beryllium copper centre contact material provides spring retention in the socket, holding the mating pin under vibration without permanent set.
