Ideal for entry and exit for sanitary environments including bathrooms, clean rooms, hospitals, labs, schools or offices, the 474 Sanitary Touchless Exit Switch from Security Door Controls (SDC) uses an IR sensor to achieve a four-inch read and up to five-inch sensing range. Users wave their hand in front of the device to open the door. Designed to control electric locks/strikes, magnetic locks or automatic door operators, other features include a durable, stainless steel plate; a dual LED illuminated sensor, where red/green indicates inactive/active status; and a quick connect screwless terminal block for easy installation.
