The Autonics BL13-TDT Liquid Level Photoelectric Sensor uses a through-beam sensing type with a fast 2ms response time for accurate liquid detection in transparent pipes. Powered by a 12β24VDC supply and consuming only 30mA, it features an infrared LED (950nm) for stable performance, even under varying light conditions. The Light ON/Dark ON mode is selectable via a button, allowing easy adaptation to control requirements. Designed with an IP64 protection rating and a durable polycarbonate case, it ensures long service life in industrial environments.
The sensor provides an NPN open collector output, making it compatible with most PLCs and controllers. Its cable type connection (Γ2.5mm, 1m) simplifies installation and reduces downtime. It supports pipe diameters from Γ6 to Γ13mm using the included binding band, and up to Γ12.7mm with a mounting bracket. This flexibility makes it suitable for a wide range of process setups in industries that rely on precision fluid control.
