12-Circuit Right-Angle Friction Lock Header
The 171857-1012: This is a Molex KK 0.100-inch (2.54 mm) pitch pin header, 12 circuits, right-angle orientation with a friction lock. The friction lock provides audible and tactile feedback on mating, and holds the connector pair against vibration in equipment that sees moderate shock — think control panels, appliances, or point-of-sale terminals where the harness is routed near a moving door or drawer.
