Surface-mount right-angle header for tight board-edge harness connections
Fastening is a locking ramp — the mating receptacle must have the matching latch feature to lock the pair together; without it the connection relies on friction alone.

Product details
Frequently asked questions
What is the mating connector for TE 2-1445057-4?
2-1445057-4 is a header that mates with a Micro MATE-N-LOK receptacle housing (wire-side) that has a locking ramp feature. The exact mating part depends on your wire gauge and circuit count; the receptacle housing and crimp terminals are sold separately. Confirm the mating half has the matching latch to engage the locking ramp.
What is the current rating of 2-1445057-4?
The current rating is listed as 'Varies by Wire Gauge' — the header itself does not set a single ampacity; the limiting factor is the wire size and the crimp terminal used in the mating receptacle. For a given wire gauge, refer to the Micro MATE-N-LOK terminal derating curve in the product drawing.
Is 2-1445057-4 RoHS compliant?
Yes, it is ROHS3 Compliant.
