China Sliding Gate Safety Sensors WS-212

When the sliding gate infrared beam is interrupted, the WS-212's relay output signals an industrial door or gate control to open, stop or reverse. On pedestrian swing doors, the WS-212 is mounted on the guide rails. When the door is closing and the overhead safety sensor is locked out, interrupting the WS-212 beam will bring this sensor protecting the swing side of the door back into the safety circuit thus inhibiting the door from reopening.
