One-Way Actuation Switch – SN2170 series SN2170-SL7-R SUNS

Possible Applications

The SN2170-SL7-R is primarily utilized as a directional limit switch in automated material handling systems, such as conveyor belts and palletizing lines, where it detects objects moving in a single direction while ignoring reverse travel. Its robust metal housing makes it suitable for heavy-duty industrial environments like automotive assembly plants or sawmills, where mechanical impact and debris are common. The inclusion of a manual reset mechanism ensures that the switch remains in a tripped state after an actuation, providing a critical safety interlock for processes that require operator intervention before a machine cycle can resume. This configuration is ideal for monitoring the end-of-travel position on automated shuttles or sliding gates where precise, unidirectional position sensing is required to prevent mechanical overtravel or collision.
