When moving parts equipped with safety edges strike the operator, these flexible safety edges are compressed and send a signal to the power source to stop the movement of these parts.
Safety edge is also called safety edge and anti-collision strip. Usually safety edges appear in various workshops, workshops, safety gates, automated mobile equipment and AGVs. It is used to protect our safety issues. In general, the safety rate of the safety edge is very high. When our personal safety is threatened, when the moving parts equipped with the safety edge hit the operator, these flexible The safety edges of the components are compressed and send a signal to the power source to stop the movement of these components.
At present, most of the safety contacts on the market are of the normally open type. When there is no trigger, the contact is normally open. When it hits a person or object, the signal is closed. The main controller collects the contact signal and stops the equipment or powers off. However, the contact edge is an impact object. With the increase of the impact force and impact frequency, the product damage rate is high. There will be phenomena such as disconnection of product joints, wire damage and other equipment that cannot be detected. After the contact edge is damaged, it cannot be used for safety protection. effect. Therefore, the safety contact edge is similar to the emergency stop switch. When the contact of the emergency stop switch cannot be connected due to a fault, or the connection is disconnected, if the normally closed point is used, the equipment can not be started, thus prompting maintenance; Normally open, it may cause hidden troubles. When emergency stop is required, it cannot be effectively stopped, which may cause the failure to expand.
Aiming at this potential safety hazard, our company has developed a safety edge control that converts the signal normally open signal into a normally closed signal, monitors the system for short circuit or open circuit, and displays its status with LED indicators, allowing the equipment to detect Whether the safety contact body is broken or damaged, the fail-safe principle is applied to improve product safety.
Safety touch controller product features:
▪The normally open signal of the safety contact is turned into a normally closed signal to improve product safety.
▪Safety touch edge disconnection detection alarm, monitor the system for short circuit or open circuit, and display its status with LED indicator.
▪Support traditional normally open and series resistance safety contacts.
▪Output normally open and normally closed signals are optional.
