FAQ
What should an electromagnet RFQ include?
Supply voltage (DC or AC), required force and stroke, duty cycle, envelope and mounting, operating environment, and sample and annual quantities.
Push-pull solenoid vs. holding electromagnet?
A push-pull solenoid moves a plunger in a straight line for locks and mechanisms; a holding electromagnet clamps steel parts when energized, for fixturing, lifting and door holding.
