How does a 2 wire door lock actuator work.

If you reverse the polarity on the actuator and apply power it flips in the other direction. The result would be when you hit your lock button the corresponding wire from your alarm will charge the relay switching the current to the 87 terminal and charging the actuator. Actuators can be designed to fail open in the case of actuator failure the valve will stay open or fail close in the case. For use with vehicle keyless entry security systems two wire reverse polarity operation universal mounting hardware included.

You should see the voltage polarity toggle with each switch activation. Inside the power door lock actuator this system is quite simple. This manipulates a series of rods that slide back and forth opening and closing the locking mechanism at the door latch. A small electric motor turns a series of spur gears that serve as a gear reduction.

Then you would wire your actuators to the 87 terminal of each relay normally open. Door lock systems operate the actuator by toggling positive negative voltage to the actuator. When power is applied the actuator flips in one direction. Be aware this product will draw 8 ma of current 24 7 or 5 8 amp hours per month out of your battery in addition the energy to open close the lock as many times you do that each day or week.

The 2 wires named battery red wire after the fuse to positive 12 vdc and the black to ground or minus battery pin. To lock or unlock the vehicle polarity is changed on one motor leg via a positive pulse from a switch alarm keyless entry etc. The actuator runs off 12 volts. Door locks actuators reverse polarity positive switch trigger type d.

Gun style actuator converts manual doorlocks into power doorlocks for vehicles that have limited installation space or require shorter actuating distance. At a basic level an actuator is a control mechanism that is operated by an energy source. I only need it to flip in one direction so i am not worried about the polarity reversal i will manually be moving the actuator to lock it. Both motor legs rest at ground at the relays.

Unplug the door lock actuator electrical connector. On manual locks the locking function operates by pushing or pulling on the door lock. The last gear drives a rack and pinion gearset that is connected to the actuator rod. How a door lock actuator works.

I want to use an arduino to activate a two wire actuator automobile power door lock mechanism. On a vehicle with electric locks the process is a bit different.
