LS-Series

Essen deinki’s LS Series all-purpose limit switches are like Swiss Army knives for industrial applications. They come in various configurations, such as 1 normally open (NO) + 1 normally closed (NC), 1 NO + 2 NC, 2 NO + 1 NC, and 2 NO + 2 NC contacts, giving you options to fit your circuit control needs.

These switches are equipped with silver contacts designed to keep contact resistance low, ensuring they work reliably. They also have a long lifespan both mechanically and electrically, thanks to their robust contact springs. These switches can handle a high frequency of up to 3000 switching cycles per hour, which is impressive.

And the best part? These switches comply with the IEC 947-5-1 standard, ensuring they meet industry requirements and can be trusted in demanding industrial settings.
