TCT Push Pull solenoid Push pull solenoid is mainly composed of casing, fixed iron core, moving iron core and the coil four parts. The coil is electrified, the movable iron core to generate axial motion in a straight line, to push, pull the external load device function. Due to the high magnetic materials and with a cone with themagnetic structure, so the product is small in volume, light in weight,but compared with the conventional small solenoid, the stroke and the attraction is large
