A safety door switch is a safety device used to monitor and control the opening and closing state of the door to ensure the safety of the workplace. It is also known as safety door lock, safety switch, safety door lock switch, electromagnetic lock safety switch, etc. This article will introduce the function, type and use scenario of the safety door switch.

The role of the safety door switch is to monitor the switch status of the door, if the door is not correctly closed or there are people entering the access control area, it will be transmitted to the control system through the signal, triggering the alarm or stopping the operation of the machine to prevent accidents. It is mainly used to automate equipment and production lines to ensure the safety of staff and equipment.

According to different working environments and needs, there are many types of safety door switches. Here are some common safety door switches:

1. Access control switch: This is the most basic type of security door switch, usually installed on both sides or the top of the door. It controls the operation of the equipment by detecting the opening and closing state of the door and issuing a signal. If the door is not closed or someone enters the access area, it triggers a stop signal to ensure the safety of the work area.

2. Electronic security door lock: Electronic security door lock combines access control switch and locking mechanism. It controls the door lock via an electronic signal, and the device only operates when the door is fully closed and locked. This security door lock can prevent unauthorized personnel from entering or leaving dangerous areas, ensuring a safe working environment.

3. Grating safety door switch: Grating safety door switch uses infrared grating technology to emit light beams through infrared sensors. When objects or personnel enter, the light beam is blocked and the stop signal is triggered. The grating safety door switch can provide greater flexibility and accuracy, suitable for complex working environments and high safety requirements.
