The red and black wires are the power lines of the electromagnetic lock, which are divided into positive and negative wiring and energized. The input voltage is DC33V30MS current 1.5A; 2. When the switch is connected to the power supply, the push rod is extended, and at the same time, the push rod is pushed against the driving pin seat slope, causing the pin seat slide to move the lock pin laterally. When the reverse voltage is passed, the electromagnet can reset the slide rod and indent the unlocked pin by the internal spring force.PackageList:1 X Embroidery Machine Electromagnet Skipping Stitch Motor
