It is the unmated half that receives the matching receptacle header in a wire-to-wire or wire-to-board interconnect. The housing is moulded in natural polyamide (PA66) and snaps into a panel cutout for tool-less retention — no mounting hardware needed. Rated for -55°C to 105°C operation, it handles the thermal range found in industrial control cabinets and under-hood automotive environments. ## Contacts are ordered separately — here is what fits The 2178474-2 ships as a bare housing: contacts are not included. It accepts both male and female crimp terminals, so the same housing can serve as either the pin or socket side depending on which contact you load. The Universal MATE-N-LOK series uses standard TE crimp contacts — the exact part number depends on wire gauge and plating preference (tin for general duty, gold for high-cycle or corrosive environments). The single-row layout keeps insertion tool access clear, and the snap-in panel mount holds the housing rigid during wire assembly.","metaTitle":"TE Connectivity 2178474-2 Universal MATE-N-LOK Plug Housing","metaDescription":"TE 2178474-2 Universal MATE-N-LOK plug housing, 3 positions, 1 row, natural PA66, panel mount snap-in, accepts male or female crimp contacts.
