Pedestrian Presence Safety Protection
The M-227 is a safety beam sensor using 880nm pulse modulation infrared light. Each set infrared with about 75mm light spot, infrared curtains providing precise presence detection. Designed to provide pedestrian presence safety protection for single-leaf or double-leaf automatic swing door and revolving door. 4 differents lengths are optional. Mounts at the top of the door leaf to eliminate damage.
Highlight
- Detection of motion and presence
- Provide presence safety protection for automatic swing doors and revolving doors
- Ingenious structure well crafted design
- Can be mounted on the top of the door leaf and side areas of revolving door leaf
- the detection height, depth and length of sensing are can be adjusted
