4.3. Alternate Controllers
The device may be controlled by any 2-phase stepper motor controller with home sensor input.
Warning: Operating the unit without correctly wiring up the home sensor can cause permanent
damage to the unit. We do not recommend using your own controller unless you are familiar with
how to control a stepper motor with a hall sensor limit switch. The following information is
provided for reference only. Damage to the actuator or hall sensor due to incorrect wiring is not
covered by warranty.
4.4. Home Sensor Wiring
A Hall effect sensor is mounted in the device for use as a home sensor. It is part number
A1122LUA-T made by Allegro. Click here for data sheet. Your controller should be configured so
the stage stops immediately (little deceleration) when the home sensor is triggered.
• Wire colour code:
• 3.6-24 Vdc input - red
• Home signal - yellow
• Ground - black
The Hall sensor has an open-collector output. The default output is high impedance when the Hall
sensor is not active. When the sensor detects a magnet, the Hall sensor pulls the output low to
ground.
If you are not using a Zaber controller, ensure that your controller has a pull-up resistor on the
output line of the Hall sensor as shown in the diagram. The bypass capacitor is optional, but may
