The Locknetics WS-200 Motion Sensor provides hands-free, contactless switch activation for a variety of access control devices. Ideal for use where a sanitary environment is desired, such as healthcare facilities, restaurants, restrooms and more. Touchless devices greatly reduce the transmission of germs since no contact is required for access. No one wants to be pushing a medical cart or hospital bed between medical bays and have to keep stopping to open doors. The WS-200 will keep you on your way quickly and efficiently. Dual LED indicators show red for inactive and green for active status. You can program the time delay from 0.5 up to 20 seconds. Easy to install with just a few screws and easy to clean as there are no crevices.
