Original product description
The S20 is an automatic sliding door drive designed for single-leaf and bi-parting commercial entrance systems. The listed technical configuration uses a Dunker motor and accepts AC 110 V or 220 V, 50–60 Hz input.
Opening and closing speeds are adjustable from 100 to 750 mm/s, with an adjustable opening time of 0–9 seconds. The stated operating-temperature range is -20 to 50°C, and working noise is listed as below 45 dB.
The operator includes obstacle detection with automatic return, slow-speed obstruction searching, self-monitoring light barriers, and fail-safe emergency opening in the event of power failure. A sound-damping pad covers the track rail to reduce noise and protect the carriage wheels.
The standard configuration lists a drive unit, transformer, motor, decoder, basic control module, track, carrier, return pulley, service-cover holder, end stop, door bracket, belt connection, and belt-tensioning device.
Listed optional components include a motion sensor, lock latch, backup battery, and beam safety photocell. Procurement note: the supplied information contains conflicting door-capacity figures.
One section states maximum leaf weights of 200 kg for a single leaf and 160 kg per leaf for a double-leaf installation, while another lists 120 kg and 120 kg × 2. Door-width and clear-opening figures also vary between sections.
Before ordering, buyers should obtain a model-specific technical sheet and confirm the required leaf weight, leaf width, opening span, track length, sensor package, emergency-power arrangement, and applicable certification documents for the intended installation.
