What is a Safety Lock? Industrial Applications and Working Principles of Safety Switch
An electromagnetic locking safety lock switch is a common security device utilized in a variety of settings, including office buildings, shopping malls, and factories. This security door switch provides security by utilising the electromagnetic principle to lock and unlock the door. The operational principle of the electromagnetic security door lock switch is based on the principles of electromagnetic suction and release. To illustrate, consider the electromagnetic locking mechanical unlocking security door lock. When the electromagnet is energized, it generates a magnetic field that attracts the ferrous parts on the door and locks the safety door. Conversely, when the electromagnet is de-energized, the Once the magnetic field is no longer present, the door components are released by gravity, allowing the safety door to be opened. In contrast, the magnetic lock version functions in a different manner. The safety door is controlled by the controller, which is used to energize and de-energize the electromagnet.
Industrial Safety Switch Components
1. The locking mechanism is comprised of the following components: This includes mechanical components such as latches and bolts that are responsible for physically locking and unlocking the door. The locking mechanism may be electric or mechanical, and is often designed to keep the door locked in case of power failure or abnormal situations, thus ensuring safety.
2. The sensor module is responsible for monitoring the status of the door and confirming whether it is closed. This is typically achieved through the use of magnetic or mechanical contact sensors. This component is responsible for monitoring the status of the door, typically utilising magnetic or mechanical contact sensors to confirm whether the door is in the closed position. These sensors are typically linked to a control system that transmits signals when the door is not properly closed or locked.
3. Actuator: The actuator is responsible for opening or locking the door. It is usually driven by an electromagnetic coil or a motor and can be triggered by external control systems or a human-machine interface.
4. Control Circuit: The internal control circuit receives external control signals and, based on the door status and factory safety logic, performs corresponding actions, such as maintaining the door lock or unlocking it.
Electromagnetic Locking Safety Switch Operational Principle
The switch is designed to detect the status of the door. When the door is in the closed position, the sensor on the door lock will confirm this and transmit a signal to the control system indicating that the door is closed.
1. The locking process is as follows: upon receiving confirmation that the door is closed, the control system will trigger the actuator to perform the locking operation. In most cases, the solenoid coil will activate, pushing the latch into the frame or fixture and preventing the door from being opened.
2. In industrial settings, particularly those involving hazardous machinery, it is imperative that the door lock remain secured until all potential hazards, such as mechanical stops or energy isolation, have been safely disengaged. The control system monitors this function continuously via signals.
3. The unlocking process is initiated when the control system confirms that the equipment has been safely stopped. At this point, the control system sends an unlocking signal to the door lock, which reverses its operation. This retracts the latch or unlocks the pin, allowing the operator safe access to the equipment area.
Various circuit designs can be achieved through different wiring and contact combinations. Below is a wiring demonstration of our OX-W2 series safety switches in conjunction with DADISICK's LS-A and Ter-A relays.
