Design and Functions

Fig. 21: Components of the sensor (unguided variant) 

The electronic part of the sensor is basically done in a two-channel design. For safety reasons the communica-
tion interface is operated by both channels together. Each of the two channels contributes their part of the posi-
tion information transmission. In case of an error, each channel is able to signal the request for transition into 
safe state independently from the other channel.
