Electric strikes (also called electric latch release) replace a standard strike mounted on the door frame and receive the latch and latch bolt. Electric strikes can be simplest to install when they are designed for one-for-one drop-in replacement of a standard strike, but some electric strike designs require that the door frame be heavily modified.
Electric strike. Electric strike with monitoring contact. An electric strike is an access control device used for door frames. It replaces the fixed strike faceplate often used with a latch (also known as a keeper). Like a fixed strike plate, it normally presents a ramped or beveled surface to the locking latch allowing the door to close and ...
The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation.
Animation of how a power lock system works (simple relay operation) Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.
A pair of automatic doors. An automatic door, also known as an auto door, is a door that opens automatically, without the need for human intervention or usually upon sensing the approach of a person.
An electric motor, geared down to get a lower speed and a higher torque, drives a pulley at one end of a belt. The door is clamped to the belt. To open the door, the motor turns the pulley, which in turn turns the belt, which in turn drags the door. To close the door, the reverse occurs.
A gated SR latch circuit diagram constructed from AND gates (on left) and NOR gates (on right) A gated SR latch can be made by adding a second level of NAND gates to an inverted SR latch. The extra NAND gates further invert the inputs so a SR latch becomes a gated SR latch (a SR latch would transform into a gated SR latch with inverted enable).
A latch bolt is an extremely common latch type, typically part of a lockset. It is a spring-loaded bolt with an angled edge. It is a spring-loaded bolt with an angled edge. [ 1 ] [ 2 ] When the door is pushed closed, the angled edge of the latch bolt engages with the lip of the strike plate; a spring allows the bolt to retract.
