Molex 43045-1400 Micro-Fit 3.0 right-angle PCB header for compact wire-to-board power or signal connections in 3D-printer electronics, toolhead boards, and harness builds.
Why use this connector
- Micro-Fit 3.0 system: 3.00 mm pitch connector family for higher-density wiring than larger power connector formats.
- 14 circuits in a dual-row layout: useful where a board needs multiple toolhead, fan, heater, sensor, or accessory conductors through one keyed connector.
- Right-angle through-hole header: routes the harness parallel to the PCB instead of straight up from the board.
- Molex part 43045-1400: snap-in plastic peg PCB lock, matte tin plated contacts, black housing, glow-wire capable per Molex product data.

Fitment and pairing
Use this as the board-side header in a Micro-Fit 3.0 harness. For the mating cable-side housing, pair it with the live Molex Micro-Fit 14-pin receptacle housing.
Gotchas
- This is the PCB header only; crimp contacts and cable housings are separate unless your kit explicitly includes them.
- It is a right-angle board connector, not a vertical header.
- Confirm PCB footprint, keying, and mating housing before ordering for an existing board revision.
