Solenoid driver circuit diagram

Refer datasheet of TIP for technical details. By using few easily available components we can build this simple solenoid driver circuit. Input supply 12V is directly applied to the solenoid device and another end terminal of solenoid is connected with TIP transistor collector terminal. When the switch is in Off condition then Q1 transistor stays in OFF condition and solenoid can not get supply.

When the switch is in On condition then Q1 transistor becomes ON state due to the base emitter voltage and solenoid coil gets supply and then becomes electromagnet then mechanical lever feels linear motion.

By using this simple solenoid driver circuit we can control current and voltage flow in the solenoid device. Solenoid devices are widely used in different industries, starting from simple locking devices, Automotive gear box, air conditioner, clamping device, medical equipment, agricultural systems, solenoid valves etc..

This can drive the Solinoid coil up to 8A load. What is a solenoid coil? Related Posts. Last updated on March 27, Apichet Garaipoom. I love electronic circuits. I will collect a lot of circuit electronics to teach my son and are useful for everyone.

Thanks for your support. View All Posts. Previous Post Fixed voltage regulator working principle. Next Post 24V power supply circuits. The turning on and off the solenoid can be noticed by the clicking sound made by it, but to make it a bit more interesting I have connected the solenoid valve to a water pipe.

By default when solenoid is off the value is closed and hence no water comes out through other end. Then when the solenoid is turned on the value gets open and water flows out. The working can be visualised in the video below. Hope you understood the project and enjoyed building it, if you had faced any problem then feel free to post them in the comment section or use the forum for technical help. It's an added 2 parts that might not be necessary.

The voltage applied to the gate will be about 2. It might be a better example to do that circuit with the intention of driving it from an Arduino or Pi, which many would be using I expect. The mosfet will not turn off if the gate pin is not pulled down to ground. The parts list states 2 resistors, one as 1k the other as 10k. Get Our Weekly Newsletter! Helena St. Related Content. Zero Crossing Detector Circuit. The parts list states 2 resistors, one as 1k the other as 10k The diagrahm shows both as 10k The write up says the 10k is to ground the mosfet So I assume the other is actually 1k and goes to the regulator?

Thanks for doing this for other than Arduino as I am using this with a physical switch.
