Board-fit and routing check for the 10-position Micro MATE-N-LOK
The 4-794681-0: This is a 10-position, dual-row vertical header from the Micro MATE-N-LOK series, on a 3.00 mm pitch with a matching row spacing of 3.00 mm. The 0.118" pitch sets the board footprint and the per-contact current ceiling — the current rating varies by wire gauge, so the limiting factor is the terminal and the harness, not the header itself. The header is fully shrouded on four walls, which protects the male pins during mating and prevents accidental shorting against adjacent components. Board locks are present on the through-hole solder tails. These hold the header in place during wave or hand soldering and resist shear force from the cable strain after assembly — a useful feature when the harness is routed near the connector.
Mating half and harness assembly
This header mates with the Micro MATE-N-LOK receptacle housings that accept crimp terminals. The 10-position, 2-row layout is keyed to prevent mis-mating — confirm the receptacle part number for the same circuit count and row configuration before ordering. The tin post is compatible with standard lead-free soldering processes.
Temperature and application envelope
The insulation material is polyamide (nylon), which absorbs some moisture — in high-humidity environments, the derating curve for current should be consulted. The general-purpose application category covers industrial control, consumer electronics, and commercial equipment.
