Pin Configuration

Pin 1

+12V positive supply voltage with respect to ground


Pin 2

Sensor signal with respect to ground


Pin 3

Ground of the internal electronics. The pin is electrically not connected to the housing


SCL

Clock line of the I2C bus, referenced to ground*


SDA

Data line of the I2C bus, referenced to ground*



*The sensor can be operated without connecting the I2C bus. If connected, provide necessary pull-up resistors to SCL and SDA (e.g. 4.7 kOhm).
