What this 8-position plug housing is built for
The TE Connectivity 1-1564522-1 is an 8-circuit plug housing from the MCP 2.8 series, part of the Heavy Duty Sealed Connector family. The black glass-filled PBT body carries a sealed rating, and the slide-on fastening keeps assembly quick in a harness build. With an operating range from -40°C to 140°C, this housing is at home in engine compartments, industrial enclosures, and any spot where vibration and moisture are the daily reality.
Sizing the harness — pitch and position count
The 6.00 mm pitch gives you room to run 20-16 AWG wire without the terminal crowding you'd get on a tighter grid. Eight positions in two rows means the housing footprint is about 24 mm wide — check your connector cavity or bracket cut-out before committing the harness layout.
Sealed housing — what that means on site
The 'Sealed' feature on this housing means the interface between the plug and its mating receptacle, plus the wire-entry end, is designed to keep out splash, dust, and pressure wash. You still need to use the correct MCP 2.8 sealed terminal and a proper seal plug on unused cavities to maintain the IP rating. On a field repair, if you're re-pinning this housing, inspect the wire seal and the housing gasket for cuts — a damaged seal is what's really failing when intermittent faults show up after a washdown.
Crimping and terminal selection
This housing accepts MCP 2.8 tab terminals (male contacts) with a crimp termination. For a full harness build, you'll need the mating receptacle housing (same series, 8-position, 2-row) and the correct sealed terminal part for your wire gauge. The slide-on fastening means the plug pushes into the receptacle with a positive stop; no locking ramp to flip, just a clean engagement that holds under vibration.
