◇ Outline and works LST DC solenoid coil by the suction power is converted to magnetic attract upward movement of the armature rated stroke locking device put armature lock, and the feeding mechanism rapid action to attract the coil power input to the trip coil ; when the trip coil is energized again, locking device unlocked, this time by heavy armature whereabouts reset. DC solenoid release button on the top there, hands on the button, about to unlock the armature. ◇ main technical parameters 1) Rated travel: 20mm. 2) Rated Force: 0.7MPa. 3) Working voltage: DC220V or DC110V, corresponding working current 1A or 2A. 4) Ambient temperature <100 ℃; relative humidity <95%. 5) The device must be installed vertically.
