The 6-968974-1 is an 18-position blue unsealed 2.8 mm receptacle housing designed for the AMP MCP (Multiple Contact Point) interconnection system used in automotive electrical and electronic applications. The housing is constructed from PA 66 GF13 material and features CuSn4 contacts with tin plating, providing high reliability and corrosion resistance for long-term use in powertrain, safety, and body systems. This receptacle housing accommodates a wire size range up to 2.5 mm² FLR maximum and is compatible with corresponding tab housings and PCB headers for flexible connector configurations. The blue color coding aids in system identification and organization, while the unsealed design allows for cost-effective applications where environmental sealing is not required. Common applications include power distribution, signal routing, and interconnection in automotive control modules and sensor networks.
