Control via digital inputs and digital outputs 

Digital input sensor 1 activates and deactivates continuous measurement. The 

“Sensor2” digital input can be used to switch between the Single and Double deep 

modes. 

Sensor 1 

 

Continuous measurement is switched on. 

Continuous measurement is switched off. 

Sensor 2 

Double deep mode is activated. 

Single deep mode is activated. 

The IN/OUT 3 – IN/OUT 6 digital outputs give information about the current position 

of the positioning mark. In evaluation mode 1 – 8, all outputs in the following table are 

possible. In evaluation mode 9 – 13, the device only outputs via the digital outputs 

whether the positioning mark is located within the target region.
