Original Hirschmann 872-857-561

Includes terminals and seals

The Component: Genuine Hirschmann 872-857-561 2-way female automotive sealed connector housing plug. SealStar 1.2mm Series (2way 1.2 Seal Star FA Connector) 2-position receptacle socket casing (Black / PA GF / Single-Wire Sealed / Mechanical Keying Code A).

Series Taxonomy: Hirschmann SealStar 1.2mm Sealed Series System. A premium, high-integrity German automotive interconnect platform engineered by Hirschmann to support structural miniaturization. Developed to deliver uncompromising waterproof defense, high thermal threshold capacity, and flawless signal performance under extreme automotive vibration profiles.

Connector Interface: 2-position (2-way) female receptacle housing plug configuration designed explicitly for female terminal contacts. Features a compact 4.00mm pitch matrix optimized for 1.2mm wide automotive terminal pins.

Locking and Sealing Security: Environmentally sealed to a strict IPX9K high-pressure washdown classification, designed to perform continuously within a severe automotive temperature threshold certified from -40 to +150 degrees Celsius. Equipped with an integrated, high-reliability Terminal Position Assurance (TPA) secondary lock mechanism to completely eliminate the risk of contact pin back-out under heavy axial wire harness pulling. Utilizes rear single-wire insulation seals (SWS) at a 180-degree cable exit angle to construct an absolute water-tight barrier that actively blocks road spray, washdown fluids, and atmospheric moisture tracking.

Mating Complement: Connects inline wire-to-wire or wire-to-device by clicking directly onto its corresponding 2-way male inline tab partner housing assembly under Hirschmann part number 805-120-521, or matching Code A male device headers from the Hirschmann SealStar 1.2 platform.

Common Applications: Extensively specified as a factory original equipment (OE) mainstay across prominent European passenger car networks, luxury transport platforms, and motorsport wiring architectures, most prominently within BMW, Mercedes-Benz, Volkswagen Audi Group (VAG), and Porsche vehicles. Universally recognized across the auto-electrical trade as the primary wiring harness repair pigtail for high-vibration powertrain nodes, including VVT camshaft solenoid valves, variable valve timing actuators, fuel pumps, and various engine compartment sensors (frequently cross-referenced to BMW OEM numbers 7543312-02, 7615487-03, 8J0973202, 8J0-973-202, and Mercedes-Benz part number A0225451926). Highly vulnerable to primary external locking tab fatigue over extended operational lifespans or mechanical housing fractures if pried open roughly with uncalibrated tools during routine vehicle service diagnostic overhauls.

Hirschmann 872-857-561 SealStar 1.2 Series 2-Way Sealed Female Camshaft Solenoid & Sensor Plug Housing

Clear persistent engine timing telemetry faults, eliminate erratic solenoid valve drops, and reinstate maximum factory-standard environmental insulation at your vehicle's powertrain sub-circuits with the genuine Hirschmann 872-857-561 2-way female sealed connector housing. Precision-molded from heat-stabilized, glass-fiber reinforced Polyamide (PA GF) to strict original equipment global engineering guidelines by Hirschmann, this SealStar 1.2 series socket carrier block is an indispensable trade piece for executing professional sensor pigtail repairs, custom motorsport loom sectioning, and clean auto-electrical overhauls. Engineered explicitly to survive punishing dynamic forces near the engine block, transmission, and chassis, it establishes a solid, zero-clearance conduction channel that safely routes critical logic data lines, signal loops, and low-voltage current paths.

The 872-857-561 carrier housing features a 2-pole matrix layout optimized around the 1.2mm terminal footprint, handling thin-wall automotive cabling cleanly. Its distinct factory black shroud profile features Code A mechanical keying to ensure perfect alignment during assembly, preventing dangerous mis-mating errors on complex multi-sensor harness junctions. Working in absolute uniformity with its internal perimeter radial seals and rear silicone single wire insulation seals, it forms an impenetrable barrier that completely locks out road spray, hot engine oil vapors, ambient grime, washdown fluid, and abrasive dirt from tracking into the active terminal lanes. This authentic component allows independent auto-electrical trade specialists, diagnostic garages, and custom vehicle restoration engineers to deliver reliable, factory-correct wiring overhauls.
