Embedded Electromagnetic Shear Lock Concealed Electric Magnetic Door Lock with Time Delay for Access Control Systems

Embedded Electromagnetic Shear Lock Concealed Electric Magnetic Door Lock with Time Delay for Access Control Systems Electromagnet: The shear lock contains a powerful electromagnet. When an electric current passes through it, the electromagnet generates a strong magnetic field that locks the door Shear Force: In addition to the magnetic force, the shear lock utilizes the shear force between the door and the door frame to increase locking strength. This means that even if the electromagnetic force fails (such as during a power outage), the mechanical shear force can still provide a level of security Shear locks provide very high locking strength by combining electromagnetic and mechanical shear forces, making them difficult to forcibly breach Since shear locks rely primarily on magnetic force, there is no mechanical wear like in traditional mechanical locks, leading to a longer lifespan Working voltage:dc12v-dc24v Working current: DC12V starting current 1.6A maintaining current 0.22a DC24V starting current 1A, maintaining current 0.13A Feedback signal: NC - short circuit COM dry contact signal when the lock is powered on and opened. NO - disconnect the COM dry contact signal when the lock is powered on and opened Adsorption spacing: within 4mm Ambient temperature: -40℃ - +55℃ Lock delay time: 0/3/6/9 seconds adjustable (The product printed words may vary depending on the batch, but this does not affect use) Color:As Shown Material:Aluminum Alloy Package Contents: 1 * Electromagnetic Shear Lock
