BL Series - Liquid Level Photoelectric Sensors

BL Series Liquid Level Photoelectric Sensors

The BL series photoelectric liquid level sensors can detect the presence or absence of liquid in transparent pipes measuring 6 to 13 mm in diameter and less than 1 mm thick. Users can easily select between Light ON and Dark ON operation using the operation mode switch. With a compact design and easy installation, the BL series sensors are ideal solutions for non-contact detection of liquid in transparent pipes.

Compact Design

The compact sized sensor (W23×H14×L13mm) are ideal for space-saving installation.

Operation Mode Switching

Users can easily switch between Light ON and Dark ON operation modes using the operation switch button.
The green LED operation mode indicator is turned on during Light ON operation and turned off during Dark ON operation, making it easy to identify the active operation mode.
