Right-angle 18-position header for wire-to-board power
The 1-794105-1: This is a 18-position, dual-row header from the Mini-Universal MATE-N-LOK series, designed for board-to-cable/wire applications. The 4.14mm pitch and right-angle orientation suit medium-density power and signal routing where the cable exits parallel to the PCB. The shrouded 4-wall housing protects the male pins during handling and guides the mating receptacle into alignment.
Board lock anchors the header through reflow and cable strain
Integrated board locks on the mounting posts hold the header in place during wave soldering and provide mechanical retention against the shear force from cable pulls. This is a practical reliability feature for field-serviceable equipment where the cable is repeatedly disconnected. The through-hole solder tails (0.145" post length) give a robust mechanical anchor to the PCB, and the 4.14mm row spacing leaves room for traces between the rows on a standard 2-layer board.
Mating connector and termination notes
This header mates with Mini-Universal MATE-N-LOK receptacle housings and crimp terminals (sold separately). The 4.14mm pitch and locking ramp are specific to this series — confirm the receptacle part number against your wire gauge for correct terminal selection. Current rating varies by wire gauge; operating temperature range is -20°C to 105°C.
