3-Position Power Key Plug Housing
The TE Connectivity 3-1376389-4 is a 3-circuit plug housing from the Power Key series, designed for free-hanging (in-line) wire-to-wire or wire-to-board connections. The yellow PA66 glass-filled housing carries a latch lock for positive retention in moderate-vibration environments like industrial control cabinets or appliance interiors. Operating temperature spans -30°C to 105°C, which covers most sealed equipment compartments.
Contacts Are Ordered Separately
This housing ships without contacts — the listing explicitly notes Contacts Not Included. The termination method is crimp, meaning you select the correct female socket terminal for your wire gauge and crimp it onto the lead before inserting it into the housing. The PA66 material accepts standard Power Key crimp terminals; verify the terminal part number against the wire gauge range in the terminal datasheet before committing the BOM line.
