Product Details

Distance trigger cut-off on-off


The limit sensor is an electrical switch used to define the limit position of movement of the mechanical device. This type of switch is contactless and non-contact. The contact type is more intuitive, on the moving parts of the mechanical equipment, the upper limit switch is installed, the limit point stopper is installed on the fixed point of the relative movement, or the opposite installation position. When the mechanical contact of the travel switch hits the stop, the control circuit is cut off (or changed) and the machine stops or changes operation. Due to the inertial movement of the machine, this limit switch has a certain "overtravel" to protect the switch from damage. There are many types of non-contact type, common are dry reed tube, photoelectric type, inductive type, etc. These kinds of forms can be seen in the elevator.


The working principle and symbolic representation of the limit sensor are used to control the stroke and limit protection of the mechanical equipment. In actual production, the limit sensor is installed in a pre-arranged position. When the module mounted on the moving part of the production machine hits the limit switch, the contact point of the limit sensor is actuated to switch the circuit. Therefore, the limit switch is an electrical appliance that switches circuits based on the travel position of the moving part, and its operating principle is similar to the button. Limit sensors are widely used in various types of machine tools and hoisting machinery to control their travel and terminal limit protection. In the control circuit of the elevator, the travel switch is used to control the speed of the switch car door, the limit of the automatic door opening and closing, and the upper and lower limit protection of the car.
