Blue Electric Wire Rope Hoist Limited Switch Plastic Wheel Swing Arm Rotary

Working principle:

For example, the FCR006 limit switch is used to control the distance of the workbench on the crane, usually in the following order: When the crane moves forward to the limit distance, the ECR006 is activated to cause the motor speed to drop until the operation is completely stopped and the conversion Commutation circuit. The motor will move in the opposite direction (rear).

Other technical indicates

Application:

Position (rotation angle) limited switch is mainly used in the following control occasions:

- Complex crane system: operating system for controlling power supply (eg PLC), allowing crane to slow down and stop running

- Lift (hoist): Used to stop the motor when it is run to its extreme position

All combinations are used with standard systems

Can be customized according to customer requirements

Principle

Limit switch is a commonly used small current master electrical appliances. The use of the production of mechanical moving parts of the collision to make its contact to achieve the opening or breaking control circuit, to achieve a certain control purposes. Typically, such switches are used to limit the position or stroke of mechanical movement, so that the movement of machinery according to a certain position or stroke automatically stop, reverse movement, variable speed movement or automatic round-trip movement.
In the electrical control system, the limit switch is to achieve the role of sequential control, positioning control and position of the state detection. Used to control the travel and limit protection of machinery and equipment. Construction: consists of an operating head, a contact system and a housing.
In the actual production, the limit switch is installed in the pre-arranged position, when installed in the production of mechanical moving parts of the module hit the trip switch, the limit switch contact action to achieve the circuit switch. Therefore, the trip switch is a movement of the parts according to the location of the switch circuit of electrical appliances, and its role is similar to the principle of the button.
Limit switches are widely used in various types of machine tools and lifting machinery, to control its travel, the terminal limit protection. In the elevator control circuit, but also the use of travel switch to control the speed of the car door, automatic door opening limit, car upper and lower limit protection.
The limit switch can be mounted on objects that are relatively stationary (such as fixed frames, door frames, etc.) or moving objects (such as traffic, doors, etc.). When the animal is close to still life, the contact of the switch's drive switch causes the closed contact to break or break the contact closed. By the switch contact opening and closing state changes to control the circuit and the action of the body.
