Product details

Board-to-wire header for harness termination

The 5054481271: This is a male pin header from the Micro-Lock PLUS 505448 series, designed to terminate a cable assembly—not a board-to-board jumper. 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.

Frequently asked questions

Where can I buy the Molex 5054481271 connector available via RFQ confirmation?

We source the 5054481271 per RFQ. Submit a request with your target quantity and we'll quote it.

What is the difference between 5054481271 and 5054481071?

Both are 12-position Micro-Lock PLUS headers, but 5054481071 is a vertical through-hole version, while 5054481271 is a right-angle SMT version. The pitch, contact plating, and latch are the same; the difference is the mounting orientation and termination style.
