Bend edge is a long strip of rubber material that can be bent. It can be fixed on the edge where there is a danger of squeezing and shearing for safety protection. If the controller is connected, the pressure output switch signal is detected, and the personal safety can be protected by controlling the machine circuit.
Apply vertical pressure to the safety edge to make the conductors of the internal induction belt contact each other, this time causing the resistance and current to change, which will be further analyzed by the control unit. If the Escalator safety edge is installed correctly, as long as the internal induction strap is not damaged, it can function normally even if the Escalator safety edge jacket is damaged.
Storage and use environment requirements:
1) Do not store or use the Safety edge sensor in an environment exposed to direct sunlight for a long time.
2) Safety margin should not be stored and used outside the range of -35℃ to +80℃.
3) Do not store or use Safe touch outside the range of 86~106KPa air pressure
4) Do not store and use the Safety edge sensor in an environment containing strong corrosive or flammable gas.

The safety edge contact system composed of the safety edge and RS8300, SRA/B safety controller complies with the following standards.
EN1760-2 ISO1856-2 EN62061 EN ISO138849-1 IEC61508 EN60204-1
The Safety edge sensor is installed on the bottom edge of the rolling door. When a person or an object is detected in contact with it, the rolling shutter door can be made to stop moving in the countryside. Prevent Director Jia or objects. Applying vertical pressure to the safety protection edge causes the conductors in the contact belt to contact each other, which causes the resistance and current to change, and there is a control mechanism for further analysis. If the Safety protection edge is installed correctly, the safety edge will not leak water. As long as the contact belt is not damaged, it can function normally even if the safety edge is damaged.
