Solenoid Lock-style 12VDC

Solenoid Lock-style 12VDC -  Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end.

This solenoid in particular is nice and strong and has a slug with a slanted cut and a good mounting bracket. It's basically an electronic lock, designed for a basic cabinet or safe or door. Normally the lock is active so you can't open the door because the solenoid slug is in the way. It does not use any power in this state. When 9-12VDC is applied, the slug pulls in so it doesn't stick out anymore and the door can be opened.

The solenoids come with the slanted slug as shown above, but you can open it with the two Phillips-head screws and turn it around so its rotated 90, 180 or 270 degrees so that it matches the door you want to use it with.

To drive a solenoid you will a power transistor and a diode, check this diagram for how to wire it to an Arduino or other microcontroller. You will need a fairly good power supply to drive a solenoid, as a lot of current will rush into the solenoid to charge up the electro-magnet, about 500mA, so don't try to power it with a 9V battery!

People Also Ask:

Q1: How is the lock solenoid installed?

  • To make the latch when you close the cabinet or door, you must first spin it.
  • The solenoid cover screws should be removed. (One of mine was tucked away under a sticker.)
  • The E-ring ring holding the latching slug in place should be removed. Here between spring and the square brass collar, it is somewhat concealed. If you don't have the right equipment for removing them, you can generally peel them off with a screwdriver or a pair of needle-nose pliers.
  • To position the long straight side of the latch slug on the side of the lock with the mounting holes, turn it 90 degrees.
  • Reinstall the cover and replace the E-ring.
  • We'll carry out the most basic installation, in which the lock solenoid is mounted on the front of the drawers and latches against the drawer or door frame.
  • For the latch to lock when the drawer is closed, the lock solenoid needs to have enough spacing behind it for the latch to clear the frame.
  • Additionally, the latch must be able to move easily while the drawer is shut. Since the solenoid isn't very strong, it won't retreat when triggered if it's wedged in too tightly. Adding some spacers between the lock and the drawer or door will probably be necessary.
  • With #4 wood screws, position it vertically so the latch may easily slip under the drawer frame. For the screws, drill pilot holes to prevent the splitting of the wood.

Q2: How do I install the Lock Sensor and Lock Solenoid, question two?

The knock sensor must be fixed in a place that is out of the way yet where you can simply and clearly knock on the opposite side. That spot would most likely be on the inside of a door. It could be under the surface of a desk, along the side of a cabinet, or inside the face of a drawer.

You'll probably want to be able to access the programming button from wherever you set it. To fasten the perf board to the interior of the sounding surface, use 1/2" #4 wood screws. Carefully tighten the screws to secure it in place while mounting it such that the piezo is up against the surface that will be knocked. Add some spacers made of leftover lumber to the perf board to strengthen and support it. After everything has been installed and tested, secure the cables using cable ties, cable staples, or hot glue.

Q3: How does a solenoid operate?

An electromagnetic actuator called a solenoid transforms electricity into mechanical motion. A ferromagnetic plunger or plug and a coil of tightly wound wire around an iron core make up the device. During the passage of an electrical current through the coil, a magnetic field is produced.

Q4: What is the amp usage of a 12-volt solenoid?
For instance, a 12-volt solenoid valve with a 15-watt coil will demand 1.25 amps, have a high power drain when linked to a battery, and require topping up as needed.
