Overview: This item is magnetic lock that consists of an electromagnet and an armature plate used for access control door locks. By attaching this to the door frame and the armature plate to the door, a current passing through the electromagnet attracts the armature plate, holding the access control door lock shut. When power off, the door will open. It is suitable for wooden door, glass door, metal door, fire-proof door,etc. Specifications: Material: Aluminum Alloy Lock size: 38x23x168mm / 48x27x250mm Plate size: 33x11x140mm / 38x11x180mm Voltage: DC 12V Pull force: 180KG(350lbs) / 280KG(600lbs) Working mode: power-on to lock Working temperature: -10 to 55 Celsius degree (14 to 131 Fahrenheit degree) Humidity: 0 to 95%.
