The 12 circuits in two rows at 1.25mm pitch mate with the matching Micro-Lock PLUS receptacle housing. The shrouded-4-wall design protects the pins during mating and prevents misalignment. ## Latch holder and vibration resistance In industrial or lighting environments where vibration is present, this latch keeps the pair mated without relying on friction alone. Sourced to order per RFQ.","metaTitle":"Molex 5054481271 Micro-Lock PLUS Header SMD RA 12POS 1.25mm","metaDescription":"Molex 5054481271 Micro-Lock PLUS header, SMD right-angle, 12 circuits, 1.25mm pitch, latch holder, RoHS3.
