One-Way Actuation Switch – SND2170 series SND2170-SL2 SUNS

Possible Applications

Unidirectional limit switches of this configuration are commonly deployed in automated conveyor systems, packaging lines, and automotive transfer equipment to monitor the passage of parts or carrier trays. They excel in linear motion applications where actuation must occur strictly during the forward stroke, such as indexing mechanisms, pneumatic pusher stations, and sorting gates, while remaining inactive during the reverse or return movement. Bottling plants and material handling facilities utilize these devices to control sequence timing, count items on high-speed lines, or signal downstream equipment without risk of re-tripping during product rollback. Additionally, their physical setup makes them ideal for lighter-duty assembly machinery where precise unidirectional position sensing is required within compact enclosures.
