The TE Connectivity 2029110-3 is a 3-position plug housing from the VAL-U-LOK series, designed for wire-to-board or wire-to-wire power interconnects where a positive-lock mate and a wide operating temperature range are required. The housing accepts male pin crimp terminals (ordered separately) and mates with the corresponding VAL-U-LOK receptacle housing. The 4.20mm pitch provides enough creepage for moderate-voltage power circuits without forcing an oversized harness layout.
The 3-position count matches a three-circuit power or signal line — common for a small motor, sensor, or lighting tap. The 0.165" (4.20mm) pitch is the VAL-U-LOK standard, so the board footprint and housing keying are consistent across the series; a 2-position and a 4-position housing share the same per-circuit spacing. The locking ramp fastening type holds the mated pair together under vibration without a secondary latch — typical for industrial control cabinets or automotive interior harnesses where the connector sees occasional shock.
Mating and Termination
This is a plug housing only — the contacts are not included and must be ordered separately as VAL-U-LOK male pin crimp terminals. The housing accepts the crimped terminals, which are inserted and retained by the locking ramp. Panel mount is supported via an integral latch feature on the housing. The white PA66 insulation material suits internal equipment enclosures.
