It uses a latch holder for fastening and includes a Terminal Position Lock (TPA) feature that locks each contact into the housing after insertion — a detail that matters when you're building harnesses that get yanked or vibrated. The glass-filled PA66 body handles -40°C to 100°C, so it's at home in an engine bay or an outdoor cabinet. Black housing, bulk packaging.
This is a crimp-termination housing, so you'll need the matching female socket contacts and a hand or auto-crimp tool to seat them. The TPA (Terminal Position Lock) is a secondary lock that slides into the housing after the contacts are loaded — it prevents a partially seated contact from backing out under wire strain. If you've ever had a pin push out mid-harness test, you'll appreciate why this feature is spec'd. The free-hanging (in-line) mount means it floats in the harness, not bolted to a panel.
