High operational reliability in security-relevant applications requires products of the highest quality. Linear solenoids integrated into access control devices (turnstiles) ensure that in hazardous situations, the horizontal arms are turned down, and a quick passage through the turnstile is possible.
Control of the turnstiles
In the same application, our linear solenoids execute the turnstile’s control function. They make sure that authorized persons are granted access, and non-authorized persons are denied access through the turnstile.
In order to secure buildings and relieve reception staff, access controls with turnstiles are often used nowadays. They are used to control access to entrances to an office or administrative buildings, company premises, airports, railway stations or sports and leisure facilities.
The security turnstiles in these facilities are motorized. In the event of a power failure, the blocking of the turnstile is released, i.e. the brake is released and the turnstile can be moved in the desired direction by simply pushing it.
Hotels garages and many safety-critical areas need transponder or card-controlled automatic locks. Powering these locks via cable is not feasible in most cases. Therefore these locks are supplied with batteries. For mechanical operation, a bistable actuator solenoid is most suitable. Such devices have two stable end positions corresponding to the locked and unlocked state. Switching is done by short current pulses, which enables a long battery life. Other advantages are the direct linear movement, which eliminates the need for gears or/and crankshafts, speed, and variability in size, stroke length, and force.
