Signal logic
36 Version: 3.0.0
Magnetic (Hall effect) sensor
+5 V/ground
TTL level
The signal level changes when passing the limit
switch. The signal logic depends on the model type:
Models with DC motor: active high. That means:

− Normal motor operation:
low (0 V)
− Limit switch reached: high (+5 V)
Models with stepper motor: active low. That

means:
− Normal motor operation:
high (+5 V)
− Limit switch reached: low (0 V)
Magnetic (Hall effect) sensor
+5 V/GND
TTL level
Direction sensing by means of different signal levels
on the left- and right-hand side of the reference
switch: The signal level changes from 0 to +5 V when
the reference switch is passed.
