40-Position SMT Header for Board-to-Cable Signal Routing
The 72454-040LF: The SMT termination allows reflow assembly alongside other surface-mount components, reducing process steps compared to through-hole headers. A keying slot and pick-and-place feature are built into the housing, supporting automated placement and preventing mis-mating with non-keyed receptacles.
Surface-Mount Assembly and PCB Footprint Fit
The 72454-040LF uses surface-mount solder tails — no through-hole posts. The contact mating length of 0.230" (5.84 mm) ensures full engagement with the receptacle terminal.
Mating Half and Keying Compatibility
The keying slot prevents insertion of a non-keyed receptacle, reducing mis-mate risk in multi-connector panels.
