It mounts via SMT with solder retention features to hold it in place during reflow. The full 4-wall shrouding protects the male pins from bending during mating and prevents off-angle insertion — a practical advantage in field-service or high-vibration assemblies where the mating half gets plugged and unplugged repeatedly. ## Pitch, stack height, and footprint fit At 1.25mm pitch, this header fits a compact PCB footprint — the 0.049\" center-to-center spacing is common for wire-to-board connectors in space-constrained designs. With only 2 positions, it handles simple signal or low-power connections — think sensor inputs, limit switches, or auxiliary power feeds. The current rating is listed as varying by wire gauge, so the limiting factor is the wire and terminal, not the header itself. ## Mating and termination Termination is solder to the PCB surface-mount pads. The push-pull fastening type means the mating receptacle latches with a simple push and releases with a pull — no screw locks or secondary hardware. ## Sourcing and compliance status No stock-holding claim; sourced per RFQ.","metaTitle":"Molex 5055680271 Micro-Lock PLUS Header, 2-Pos, 1.25mm","metaDescription":"Molex 5055680271 Micro-Lock PLUS 505568 header, 2 positions, 1.25mm pitch, SMT, shrouded 4-wall.
