The TE 2-1418390-1 is a 4-position, 2-row receptacle housing from the Heavy Duty Sealed Connector Series, MCP 2.8 family. It's a free-hanging (in-line) connector with a 6.00 mm pitch and matching 6.00 mm row spacing — the square cavity layout is straightforward to wire on a bench. The gray PBT, glass-filled housing is rated for -40°C to 140°C, which puts it in the range for engine-bay, industrial cabinet, or outdoor equipment where standard 85°C connectors soften. The sealed feature means the mated pair keeps out moisture and dust when used with the correct mating plug and sealed terminals.
The One Spec That Decides the Fit: Contacts Not Included
The most important line on this listing is the note: Contacts Not Included. This housing is a shell — it ships empty. The 6.00 mm pitch and 2-row layout take standard MCP 2.8 contacts, but the exact terminal part number depends on your wire gauge and plating preference (tin vs silver). If you're filling a BOM line, make sure the terminal line item is there; otherwise the harness stops at the crimp press.
The -40°C to 140°C operating range is the standout rating. That 140°C upper limit is well above the 105°C or 125°C ceiling of many automotive-grade connectors — it tells you the PBT housing material was chosen for continuous exposure near a hot engine or industrial heat source. The sealed feature adds washdown and splash resistance, but the seal integrity depends on using the correct mating plug (also sealed) and the proper crimp terminals with wire seals. Slide-on fastening means quick assembly and no tools for mating, but for high-vibration environments you'll want to verify the lock retention with the specific plug design.
