Limit switches or limiters have unlimited applications in the industry. Adjusting the performance of different movements in displacement systems is one of the most important tasks of limit switches. When moving the load, you can set a range for the load and prevent the load from approaching the lift. Limit switches When the crane goes out of the set limit, it issues a stop command and causes the crane to stop. Limiters control the movement of the crane and prevent collisions and damage to the crane or possible irreparable damage. Limit switches are used in various industries to control the limit, state, status display, part counting and many more. Limit switches are used in industry to detect the proximity or absence of an object or material or its absence. Limit switches on doors and small dimensions are called micro switches. When an obstacle is placed in the path of movement with the crane, the limit switch prevents collision, and causes the crane to stop by cutting off the electrical circuit. Limit switches have a variety of applications in different environments and working conditions due to their industrial structure of strength and ease of use and installation and completely safe operation, for example, conveyors, cranes, automatic machines, forklifts and in general in most machines. Used to control dimensional movements. Most limiters work with a relay, or contact.
Advantages of crane switch limits:
1. Easy to install and easy to use
۲. The price is right
3. It has a completely industrial and durable body
4. High accuracy and repeatability
5. Input current tolerance
6. Noise resistant
7. Simple operation NO, NC
Disadvantages of crane switch limits:
1. Shorter life than proximity (optical) sensors
۲. Malfunction of moving parts
