Installation Method
Determine the installation location: Based on the travel range of the equipment's moving parts, install the limit switch near the end of its travel to ensure that the limit switch accurately detects when the part reaches the set position.
Choose a mounting method: Common mounting methods include bolting and clamping. Select the appropriate mounting method based on the limit switch type and equipment structure. Use appropriate fasteners, such as screws or clamps, to securely secure the limit switch in the selected location.
Ensure the relationship between the trigger component and the moving part: Ensure that the limit switch's trigger component, such as a striker or roller, is perpendicular to the contact surface of the moving part, leaving a 1-2mm gap to prevent rigid impact. In high-frequency impact scenarios, rubber cushions can be added to absorb energy.
Connecting the circuit: A limit switch typically has three pins: common (COM), normally open (NO), and normally closed (NC). Connect one end of the cable to a power supply, controller, or other device, and the other end to the corresponding pins on the limit switch. If you need to trigger an alarm or signal when the machine stops, connect the cable to the NO terminal; if you need to trigger a signal or alarm when the machine reaches a certain position, connect it to the NC terminal.

Debugging Methods
Installation and Fixing Check: Verify that the limit switch is correctly installed and securely fixed, without any loosening or falling off.
Manual Trigger Test: Manually trigger the limit switch to observe whether it is properly issuing a control signal. This can be confirmed by observing the indicator light on and off or by measuring the continuity of the circuit with a multimeter.
Adjusting Trigger Sensitivity: If the limit switch's trigger sensitivity does not meet requirements, adjust the spring tension or contact pressure. Adjustments should be made gradually, and the switch's response should be observed.
Simulation Test: Power on and perform a simulation test on the mechanical equipment to observe the limit switch's performance during actual operation. Ensure that it triggers at the correct time and accurately controls the mechanical equipment's travel.
Monitoring Contact Temperature Rise: During operation under actual load, use a thermometer or other tool to monitor the contact temperature rise. The temperature rise should not exceed 50°C to prevent contact corrosion.
Recording Debugging Results: Detailed records of debugging results, including the switch's trigger position, trigger sensitivity, circuit status, and other information, will be kept for reference during subsequent maintenance and repairs.
