One-Way Actuation Switch – SN4170 series SN4170-SL7-R SUNS

Possible Applications

This one-way actuation switch is predominantly deployed in automated material handling systems, CNC machining centers, and automated assembly lines where precise mechanical position feedback or travel-limit detection is required. In overhead conveyor systems and automated guided vehicles, the component serves as a directional travel limit sensor that triggers safely when components pass in a single designated direction while remaining unactuated on the return stroke. The robust small metal housing endures the mechanical wear and environmental stress typical of stamping presses, packaging machinery, and industrial robotic cells. Furthermore, the integrated reset mechanism makes it exceptionally well-suited for manual override setups and safety interlock circuits on sliding machine guards, ensuring reliable state changes during repetitive cycle operations.
