Pico-Lock 2053410204 — 4-Circuit Receptacle Housing
The Molex 2053410204 is a 4-circuit receptacle housing from the Pico-Lock 205341 series, designed for wire-to-board interconnects where a compact 2.00 mm pitch keeps the board footprint small.
At 2.00 mm pitch, this housing fits a compact board layout — the header footprint takes about 8 mm of board edge for the four positions. The 4-circuit count matches a 4-wire sensor, a small power tap, or a signal bundle where you need one circuit per function. The single row keeps the connector width narrow, which helps when routing the harness through a tight grommet or along a frame rail. The friction lock is a positive-retention feature: you feel the click when the housing seats fully onto the header. It resists un-mating from cable tug or machine vibration better than a simple detent, though it is not a latch you can deliberately release with a tool — it is a push-to-mate, pull-to-release design. For environments with continuous high-frequency vibration, a secondary lock or cable tie-down is worth considering.
Ordering the housing without the contacts is a common BOM gap; make sure the terminal part number is on the same line.
