The Actuonix linear actuator limit switch kit allows you to easily add external limit switches to your device.
External limit switches can be added to “S” or “P” series linear actuators. This kit provides a simple and cost-effective way to adjust the end-limits of your linear actuator. Ideal for situations where you need a custom stroke length but do not require enough units to have a custom actuator produced. The limit should be mounted so that the moving mechanism pushes the switch plunger when you wish the actuator to stop. The switch will cut all power to the actuator once pressed.Then the diodes in the circuit will allow you to reverse away from the limit by simply reversing the polarity of the voltage to the actuator.
