The TE Connectivity 1-1394765-1 is a 21-position plug from the MCP (Multi-Connection Plug) series, designed as a field-serviceable wire-to-wire interconnect for harness assemblies. Its 3-row layout and tin-plated tab contacts suit moderate-cycle applications where cost per circuit matters more than gold-plated cycle life. The panel mount, snap-in mounting lets you secure the plug to a chassis or enclosure wall, and the latch holder fastening keeps the mating pair locked under vibration — typical for automotive body harnesses, industrial control panels, or appliance wiring where a connector sees occasional disconnection but needs to stay put when mated.
21 positions across 3 rows. Solder cable termination requires a soldering iron at the harness build station.
Mounting and Locking for Vibration Resistance
Panel mount, snap-in installation means you cut a mounting hole in the panel, push the plug housing in until the retention barbs click, and it stays put without hardware. The latch holder on the mating face then locks the receptacle into the plug, creating a vibration-resistant joint that will not walk loose on a machine or vehicle. This combination makes the 1-1394765-1 a practical choice for a pass-through bulkhead connector on a control box or a harness-to-harness junction inside an enclosure.
