There are left, right, front and back limits. Limits (electronic stops) are virtual positions on the workpiece that limit the machining area (movement ranges tool) and operate in different modes of operation.

Note: this is a slightly redacted automated translation of a manual written by Oleg A. Optionally you can also wire in the fuses included with the kit but these are not mandatory.Digital Feed Electronic Lead Screw 7e2 Manual Not that the diodes come pre-installed, wired across the terminals of the switch. Wire the switches to the actuator as shown in the wiring diagrams below. Using small screws or bolts attach one (or two) of the limit switches so that the actuator will collide with them when it reaches your maximum/minimum desired position. Firstly mount your actuator in your application and determine where your upper and/or lower limits need to be. External limit switchesįirst you will need our external limit switch kit, a crimping tool or soldering iron, and heat shrink tube/electrical tape for insulation. Then you will need to mount external limit switches. These limit switches ensure that when you fully extend (or retract) the actuator it will automatically shut off preventing the motor burning out and/or doing damage to the body of the actuator. Inbuilt limit switchesĪll our linear actuators (except the Bullet Mini and Bullet 23 Cal.) have internal limit switches at the fully extended and retracted positions. If the limit switches did not have diodes wired across their terminals, the actuator would be stuck as soon as the limit switch was pressed: unable to move forwards or backwards. This is important because it allows the actuator to move in the reverse direction after reaching its limit. By wiring a diode across the switch terminals, even when power is cut to the motor, electricity can still flow in the opposite direction. Diodes is an electrical component that is equivalent to a one way valve. These switches have a diode wired across its terminals. Limit switches are spring loaded buttons that when pressed open the circuit, stopping the motor from spinning any further.

This tutorial will go over how to connect this up. Sometimes you may not want to use the entire stroke length of a linear actuator, to restrict the travel distance you will need our external limit switch kit.
