It carries female screwlocks (4-40) on the mating side for secure panel-to-cable or panel-to-panel mating. This is a standard DE-9 shell size (E layout), used for RS-232 serial ports, industrial control interfaces, and instrumentation links where a reliable signal interconnect with screw-lock retention is required.
Rated 6A per contact at 125V, the 3-106505-2 handles signal-level currents and moderate power — think control loops, sensor feeds, or low-current actuator lines.
Termination is through-hole solder — the right-angle pins pass through the PCB and are wave-soldered. The panel-mount flanges accept 4-40 screws from the mating side, and the female screwlocks on this receptacle engage with male screwlocks on the mating plug for a vibration-resistant joint. The backset spacing of 0.406" (10.30mm) sets the distance from the PCB edge to the mounting holes — check your enclosure cutout against this dimension before layout.
