    Motion detector solenoid lol

    Hey! Super beginner here, I’m looking to design a system, that a pir controls 2 push solenoids. im assuming I need a controller or a contactor, for once motion is detected I need solenoid 1 to push out, then once motion is no longer being detected I need solenoid 2 to push out, I’m a electrician...

    Solenoid Flyback protection

    I am planning to make solenoid: *Coil = 3.5 Ohm Dc - 3.5 mh inductance *Capacitor = 450v- 1000 uf *Dc Battery = 12v *Dc Booster = up to 400v *Push button switch Iam willing to operate it on 150v or 200v I am worrying about the switch to get damage by the back emf I did some research...

    design an RC snubber for ac solenoid lock ( inductive load)

    I am designning ac solenoid lock, read the inductive load needs snubber circuit to protect from inductive turnoff transients Here is my design Resistance 8 ohm Main outlet power source 220 - 50 hz Inductance 150 mh Impedance 47 ohm I (rms) ~ 5A So do i really snubber circuit? If so iam...

    Power supply turn off when latching solenoids switches ON?

    I have two 24VDC, 1.54A latching solenoids. I connected them both in parallel with power supply (80V, 80A). But when i turn ON the power supply it immediately turn off. However, when i connect a single latching solenoid with power supply it works fine. Is it necessary to use two power supplies...

    Controlled solenoid stroke length

    Let me create a scenario to better illustrate the problem I have 1500 pens that I want to individually actuate upwards with 3 different distances, ex: 10mm/15mm/20mm I thought I could use solenoids to do this, but I'm not sure if this is the best option and how accurate the solenoid will be...

    Solar charger & timer

    Hi I need help building the electronics for a home project. Essentially I am trying to: 1. Charge a battery with a solar panel 2. Activate a 12solenoid valve controlling pressurized water with a push button 3. Have the solenoid close after an adjustable time delay I was able to find solar...

    Fingerprint Module with Door lock Solenoid - Arduino Nano ..

    Greeting, Thank you for your support guys. I am a newbie to the Electronics, but I did read for a long time and search but this is my first circuit it may look easy for you but I need help. Here are two schematic and I need them to be joined together with Op protection and reverse voltage...
