Limit Switch(Rated Operating Voltage:30 VDC or Less)

Limit Switch is used to detect the presence or absence of an object and monitor the position of a moving part for example detection of incorrectly set work, loose screws, and check the status a door of machine. They find widespread application across various industries, such as automation systems, food and pharmaceutical industries, and electronics industries. When selecting Limit Switch it is crucial to consider factors such as Detector Shape (e.g., Rod Shape, Plunger Type, Lever Shape (Push) and so on), Environment (General, Cold/Heat Resistant, Water Resistant) Plunger and Lever Shape. These considerations are vital for ensuring the production of high-quality products. We highly recommend reputable brands like OMRON and RS Pro. Take advantage of the convenience of FREE SHIPPING and NO MINIMUM ORDER on Limit Switch and related products. If you have any doubts or require assistance in choosing the right product, our experts are readily available to provide advice and guidance.

                                                      FAQ Limit Switch

                                                      Question: Can the Limit switch be used for doors?
                                                      Answer: Yes, limit switches can be used for door safety functions. In fact, they are commonly used in industries to ensure the safe operation of doors, gates, and access points in automated systems. To use a limit switch for door safety, you would need a "safety limit switch."

                                                      There are two main types of safety limit switches suitable for door safety:

                                                      Mechanical Safety Limit Switches: These switches have a physical actuator that comes into contact with the door or gate, triggering the switch when the door reaches a certain position. They can be used to detect when the door is fully open or closed.

                                                      Non-Contact Safety Limit Switches: Also called "safety interlock switches" or "coded magnet switches," these use non-contact technology to detect the presence or alignment of a magnet on the door. They are more tamper-resistant and are often used in critical safety applications.
                                                      Question: What is the purpose of a Limit switch with a long lever?
                                                      Answer: A limit switch with a long lever serves the purpose of detecting the presence, absence, or position of an object with a larger range of movement. The long lever acts as an extension, allowing the switch to respond to changes in position over a greater distance. This type of switch is commonly used in applications where the movement of the object being sensed is not directly aligned with the switch itself.

                                                      For example, imagine a conveyor belt where products of varying sizes move along. A limit switch with a long lever could be positioned such that the lever comes into contact with the products. As each product passes by, it engages the lever, causing the switch to activate. The longer lever provides the necessary reach to detect objects that might be positioned farther away from the switch housing.

                                                      In simpler terms, a limit switch with a long lever is like having an extended arm that can reach out and touch something that's not right next to it.
                                                      Question: How do I connect or install a limit switch?
                                                      Answer: Step by step to install the limit switch
                                                      1. Choose Mounting Location: Determine where you want to install the limit switch. Make sure it's strategically placed to sense the desired movement or position.
                                                      2. Prepare Mounting Surface: If needed, prepare the surface by drilling holes for mounting screws or bolts. Ensure the surface is clean and flat.
                                                      3. Mounting: Attach the limit switch to the mounting surface using screws, bolts, or a bracket provided with the switch. Ensure the switch is securely fixed and aligned properly.
                                                      4. Connect Wiring: Refer to the manufacturer's wiring diagram or schematic for guidance. Typically, limit switches have several terminals: common (COM), normally open (NO), and normally closed (NC). Connect wires from your control system to these terminals based on your application's requirements.
                                                      5. Wire Connection: Strip the ends of the wires and attach them to the appropriate terminals. Use screw terminals, crimp connectors, or other suitable methods as specified by the switch's manual.
                                                      6. Secure Wires: Make sure the wires are properly secured and won't be pinched or pulled when the machine or system operates.
                                                      7. Adjust Actuator: If the limit switch uses an actuator (lever, roller, etc.), adjust its position so that it's activated when the desired movement or position is reached.
                                                      8. Test the Installation: Carefully test the limit switch by manually triggering its actuator to see if it activates and deactivates correctly. Make any necessary adjustments if it's not functioning as expected.
                                                      9. Final Check: Double-check all connections, screws, and adjustments to ensure everything is secure and properly aligned.
                                                      10. Power On: Power up the system and observe the limit switch's behavior during regular operation. Confirm that it accurately detects the intended movement or position.
