One-Way Actuation Switch – SN4170 series SN4170-SL SUNS

Possible Applications

The SN4170-SL one-way actuation switch is primarily utilized in automated material handling systems and conveyor lines where directional sensing of moving parts is required. Its mechanical design allows it to trigger a control signal only when an object passes in one specific direction, making it ideal for counting components or detecting the presence of pallets on assembly lines without triggering false signals during reverse movement. This switch is frequently integrated into packaging machinery and robotic work cells to monitor the positioning of sliding gates or safety guards that must be tracked during a single-cycle operation. Because of its robust metal housing, it is well-suited for industrial environments where mechanical durability is necessary to withstand repetitive physical contact from moving machine components.
