The comfort SIDOOR AT12 elevator door drive is an intelligent door control system which enables the opening and closing of cabin and shaft doors at adjustable speeds and accelerations.

The maintenance-free, variable speed drive unit comprises a DC motor with non-self-locking gearing. The SIDOOR M2 geared motor (24 V DC/1.8A; motor for max. total door leaf weight of 120 kg) must be ordered separately > see"Geared motors".

Operation of the door drive does not require a limit switch. The door width and the "OPEN"/"CLOSE" positions are determined automatically.

The current operating states are indicated via an LED with a flashing code integrated in the SIDOOR AT12 Elevator Door Drive or externally via a Service Tool > see"Additional units".

Power transmission is via a toothed belt which passes over a guide pulley and which can be fitted with two door clutch holders. These accessories are not included in the scope of delivery > see "Accessories".

This enables handling of both one-sided and centrally opening doors.
