872-406-501 SealStar 1.2mm Series 2-Way Housing

Hirschmann 872-406-501 SealStar 1.2mm Series 2-Way Shroudless Female Sensor Plug

Restore flawless data signaling and ultimate moisture isolation to low-voltage exterior body telemetry loops with the genuine Hirschmann 872-406-501 2-way female connector plug. Precision-engineered by Hirschmann to strict original equipment manufacturer parameters, this 2-pin single-row receptacle housing belongs to the high-density SealStar 1.2mm shroudless interconnect family. Outfitted with an integrated internal high-compression silicone face seal and individual cable-entry tracks, it forms a robust environmental barrier certified to IPX7 and IPX9K standards, deflecting high-temperature oil vapors, road spray, salt fog, and targeted high-pressure steam cleanings.

The 872-406-501 carrier block is molded from premium glass-fiber reinforced polyamide (PA66+GF) finished in an industrial black tone, delivering outstanding structural rigidness and defense against thermal aging across a severe operating temperature window of -40°C to +150°C. The internal 2-position cavity matrix operates on a compact 4.0mm centerline pitch, engineered explicitly to accept 1.2mm width female socket contacts—including TE MCON 1.2 and Kostal MLK 1.2 series terminals. It utilizes clean mechanical Coding A rails to ensure foolproof, error-free mating on dense wiring branches. Extensively relied upon across European platforms (particularly as a primary BMW service component) to manage 2-wire comfort entry door handle sensors, exterior mirror telemetry, turn signal lamps, and fender thermostat sensors, this authentic replacement housing enables harness specialists to execute clean, zero-resistance factory pigtail repairs right on the service bench.
