The 1.25 mm pitch sets the PCB footprint — tight enough for a compact board but still routable on a standard two-layer design. The right-angle SMT orientation routes the mating cable parallel to the board surface, which helps when the z-height budget is under the 3.90 mm insulation height. The shrouded 4-wall housing protects the pins during handling and guides the receptacle into alignment. ## 30 µinch gold — field-service duty Both the mating and post contacts carry 30 µinch gold over nickel. ## Locking ramp and UL94 V-0 housing The locking ramp on the header mates with a corresponding latch on the receptacle, providing a positive hold against vibration — a common requirement in automotive and industrial applications. ## Active production, ROHS3 compliant Listed as Active with no end-of-life notice. ROHS3 compliant, which covers the full RoHS substance scope including the four phthalates.","metaTitle":"5055670451 Molex Micro-Lock PLUS Header, 4 Circuit","metaDescription":"5055670451 Molex Micro-Lock PLUS 505567 header, 4 circuits, 1.25 mm pitch, SMT right angle, gold plating.
