Air Curtain Door Sensor

Model No. 1L-AC-101S

The 1LAC101S is a precision-engineered Air Curtain Door Sensor designed to deliver intelligent automation for air curtain systems. Utilizing magnetic reed switch technology, it enables automatic ON/OFF operation—activating the air curtain instantly when the door opens and turning it off the moment the door closes. This not only ensures maximum energy efficiency, but also significantly reduces unnecessary runtime, minimizing wear and extending the overall lifespan of your air curtain unit.

Built for reliability and durability, the 1LAC101S performs consistently even in high-traffic or industrial settings. Its seamless functionality makes it an ideal choice for energy-conscious businesses operating in cold storage facilities, warehouses, production areas, supermarkets, and other climate-controlled environments.
