Detection of people for automatic opening of doors

The position of pushbuttons for doors in public transportation vehicles are often not designed for the needs of wheelchair users. To accommodate individuals in wheelchairs, the WTB27-3 compact photoelectric sensor is mounted above the door to accurately detect when a wheelchair user approaches the door. The sensing range can be adjusted to reliably detect objects close to the ground (e.g., footrest). The door then opens on time and the wheelchair user can pass unhindered.
