Instruction Manual


Approx. 20 g

*1 The number of control outputs for the M8 connector (3 pin) type is 1 output. If "D" is at the end of the model code, the sensor is equipped with a Dark-ON output.
If "L" is at the end of the model code, the sensor is equipped with a Light-ON output.
Example: The PR-M51C3PL has a Light-ON output (output 2). (The response time also becomes the output 2 response time)
