Hirschmann 805-120-521 SealStar 1.2 2-Way Female Sealed Plug

Terminals and seals are included

The Component: Genuine Hirschmann 805-120-521 2-way female automotive sealed connector housing plug. SealStar 1.2mm Series (2way 1.2 SealStar FA Connector) 2-position receptacle socket casing (Black / PA66 GF25 / 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) single-row female socket plug configuration featuring a compact 4.00mm centerline pitch matrix. Designed with an internal contact alignment track keyed specifically to house standard 1.2mm width female socket terminals (such as TE Connectivity MCON 1.2 LL or Kostal MLK 1.2 series contacts).

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 a pre-assembled, integrated top-mounted Connector Position Assurance (CPA) locking slide mechanism to guarantee perfect hardware latching and safeguard the connection against severe chassis harmonics or engine-block resonance. Employs a robust, high-performance inner radial silicone perimeter compression seal combined with matching rear individual single-wire insulation seals (SWS) at a 180-degree straight cable exit angle to construct an absolute water-tight barrier. Fully designed according to strict USCAR specifications and LV-214 guidelines.

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 (such as Hirschmann 805-120-521 related couplings) or matching Code A male device headers from the Hirschmann SealStar 1.2 platform, including companion parts like 872-857-561 or 872-863-561 / 7 547 844-30.

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 daytime running lights (DRL), fuel injectors, crash impact sensors, camshaft adjusters, parking radar sensors, and various low-voltage engine compartment telemetry circuits (frequently cross-referenced to BMW OEM number 7615487-03 and Mercedes-Benz part number A0225451926). Highly vulnerable to physical locking arm distortion, CPA tab fatigue over extended operational lifespans, or internal channel fracture if pried open roughly with uncalibrated tools during routine vehicle service diagnostics.

Hirschmann 805-120-521 SealStar 1.2 Series 2-Way Sealed Female Injector, DRL & Sensor Plug Housing

Clear persistent engine timing telemetry faults, resolve flickering daytime running lights, and reinstate maximum factory-standard environmental insulation at your vehicle's safety or fuel management circuits with the genuine Hirschmann 805-120-521 2-way female sealed connector housing. Precision-molded from heat-stabilized, glass-fiber reinforced Polyamide (PA66 GF25) 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 (≤ 60 V DC).

The 805-120-521 carrier housing features a 2-pole matrix layout optimized around the 1.2mm terminal footprint, handling fine-gauge automotive wire sizes from 0.13mm² to 1.00mm² 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 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.
