It uses a 4.00 mm pitch, which gives the contacts enough spacing to handle moderate current without forcing a wide connector footprint. It's the 4-circuit member of the MCON series, a family known for its compact, sealed, high-vibration-rated interconnects used in engine compartments, transmission interfaces, and sensor harnesses.
What the key features mean for a harness build
The Connector Position Assurance (CPA) feature is a secondary lock that snaps over the primary latch holder. In a high-vibration environment — think a vehicle firewall or an industrial machine cabinet — the CPA prevents the housing from backing off the mating header if the primary latch gets bumped or vibrates loose. It's a simple mechanical backup that saves a warranty return. The housing itself is a shell — the electrical connection happens at the crimp barrel. The PA66 (Nylon 6/6) insulation material handles underhood temperatures and resists common automotive fluids. It's a standard choice for this class of connector — tough enough for the engine bay, light enough for a harness bundle.
