12 Volt Electric Linear Actuator Wiring

Introduction: 12 Volt Electric Linear Actuator Wiring

About: Progressive Automations is your primary source for electric linear actuators, motion control systems and automation accessories. For over a decade, we have supplied various industries with top quality automati…

In this instructable, we will go over 12-volt linear actuator wiring (common methods used) and a basic understanding of how an actuator works.

Step 1: Wiring With a Rocker Switch

The simplest control system for a 12VDC linear actuator for a user to implement will have to be a DPDT (double pole double throw) rocker switch. It can output DC current in both directions from the power supply, therefore it can control the linear actuator to extend and retract.

The upper-left and lower-right terminals are connected to the ground of the power supply. The upper-right and lower-left terminals are connected to the +12V terminal of the power supply. The middle-right and middle-left terminals are connected to the 2 inputs from the actuator.

Step 2: Wiring With a Control Box

Depends on the application, many users would prefer to control the linear actuator with a control box. At Progressive Automations, we offer a large variety of control box options. They mostly plug and play, so there is very little need for additional wiring. They can generally be summarized into two simple steps.

Connect the output of the control box to the input of the linear actuator. Connect the input of the control box to the output of the power supply.

Step 3: Wiring With a Custom Control System

It is also possible to control the linear actuator with your own custom control system. Depends on your applications and control system requirement, the schematic for the control system can be vastly different; however, the connection terminals for the linear actuator itself should remain consistent. The terminals you need to find are the +12VDC output terminal and the -12VDC output terminal. These should usually be labeled with +V and -V signs. No matter how complicated the custom control system is, the final output signal needs 12VDC current to drive the linear actuators. Look for any labels on the control unit or find them in the user manuals.
