Autonics BL Series Instruction Manual

BL Series
Liquid Level Sensor for Mounting Pipe (Through-Beam)
Features
● Detects liquid in a transparent/semitransparent pipe
diameter Ø6 to 13mm, thickness 1mm
● Compact size: W23×H14×L13mm
● Selectable Light ON/Dark ON operation mode
by operation mode switching button
● Easy to check operation status by operation mode indicator
[green LED (Light ON: on, Dark ON: off)],
operation indicator [red LED]
● Built-in reverse polarity protection circuit and
output short overcurrent protection circuit
● IP64 of protection structure (IEC standards)
Please read "Safety Considerations"
in the instruction manual before using.
