One-Way Actuation Switch – SND2170 series SND2170-SL SUNS

Possible Applications

The SND2170-SL is engineered for directional sensing and position monitoring in automated material handling systems, such as conveyor belts and sorting lines, where it detects objects moving in a single direction. Its slow action contact configuration makes it ideal for integration into safety interlock circuits on machine guards or access panels where a deliberate, non-latching signal is required to confirm closure. In packaging machinery and assembly automation, this switch serves as a reliable limit sensor for indexing components or tracking the travel of pneumatic actuators. Because it lacks a reset mechanism, it is best suited for processes where the mechanical trigger is cleared by the natural flow of the workpiece, ensuring consistent cycle monitoring without manual intervention.
