For a field-service tech swapping a cable assembly, that lock is the difference between a connector that stays mated and one that walks loose.
Footprint and Routing Constraints
Bottom-entry orientation means the header body sits flush against the PCB, with pins exiting the opposite side — typical for wire-to-board applications where the cable enters from below the board.
Termination is solder-only — no press-fit or IDC option.
The base product number BE3P-SHF is shared across the NH series — the full suffix (LF)(SN) indicates lead-free solder plating and RoHS compliance. The housing is natural nylon 6 with UL94 V-0 flammability rating.
