In a crane monitoring system, the choice of using mechanical limit switches or proximity switches depends on the specific application needs and working environment. Here is a brief introduction to both types of switches:
Mechanical limit switch: Mechanical limit switch detects the position of an object through physical contact. They usually consist of a movable arm and a contact point. When a target object comes into contact with the movable arm, the contacts open or close to send a signal. Mechanical limit switches are suitable for applications that require precise detection of position, such as ensuring that mechanical equipment is in the correct position when starting or stopping motion.
Proximity switch: Proximity switch uses non-contact sensing technology, such as magnetic induction, infrared or ultrasonic waves to detect the proximity of objects. They are usually installed near mechanical equipment, and when a target object approaches, the switch detects and sends a signal. Proximity switches are suitable for applications where the position or distance of a target object needs to be detected without touching it. They usually have high sensitivity and fast response characteristics.
Considering the following factors can help you make your choice:
1. The working environment of the crane, such as temperature changes, humidity, dust levels and other factors.
2. The accuracy and precision required for the switch, as well as the size and shape of the target object.
3. Whether the object that needs to be detected is metal or non-metal, because the proximity switch has different detection sensitivities for metal and non-metal.
Before making a decision, it is recommended that you have a detailed discussion with the crane manufacturer or crane monitoring system supplier and understand their recommendations and recommendations. They will have deeper knowledge and experience and help you choose the type of switch that best suits your application needs.
