Linear Solenoid Pulsed
I have this part from RS: https://docs.rs-online.com/4238/0900766b81679254.pdf.
I understand quite well about why the solenoid can output more force (given same distance) or have higher power input (W)...

Is my PCB ready for PWM solenoid control?
I am looking to upgrade my project to handle "back EMF" from solenoids when used in PWM mode in combination with MOSFET.
The original project lives on a breadboard, and I am attempting to ...

Solenoid fails under PWM control
I have a 12V solenoid rated at about ~6W and 40kg pull.
I am controlling it using ESP32, IRLB8721PBF logic-level mosfet.
MOSFET gate-gnd is also connected using 0.5W 5.6V zener diode.
ESP32-gate is ...
