Product Details
Types of Limit Switches
- Mechanical Actuated: Activated through physical contact using levers, rollers, or plungers.
- Non-Contact/Magnetic Actuated: Operates without physical contact, often used in sensitive or high-speed applications.
Configurations
- Normally Open (NO): Completes a circuit when the switch is activated, often used where the circuit should remain open until the switch is engaged.
- Normally Closed (NC): Interrupts the circuit when the switch is activated, ideal for applications where a closed circuit is required until engagement.
| Question | Purpose | Description |
|---|---|---|
| 1. What is the Application? | Determine the purpose of the limit switch in the system. | Understand if the switch will be used for positioning, safety interlock, emergency shutdown, or another purpose. |
| 2. What Switching Type is Required? | Identify the necessary configuration for the circuit. | Select either normally open (NO) or normally closed (NC) based on operational needs. |
| 3. What Electrical Rating is Needed? | Ensure compatibility with the system's electrical parameters. | Choose an appropriate voltage and current rating to match system requirements (e.g., 24V, 110V, 220V). |
| 4. What Actuation Method is Required? | Specify the desired type of actuation for accurate operation. | Options include lever, roller, plunger, or magnetic actuation based on the application’s mechanical and space constraints. |
| 5. Are there Mounting and Size Constraints? | Accommodate any specific spatial or mounting limitations in the setup. | Determine space limitations and required mounting arrangements for easy and effective installation. |
| 6. What is the Environmental and Protection Rating? | Ensure durability in harsh or hazardous environments. | Consider IP or explosion-proof ratings for protection against dust, moisture, or hazardous conditions (e.g., IP67, explosion-proof). |
| 7. What is the Operating Temperature Range? | Confirm the switch can operate reliably within the system’s temperature conditions. | Select a limit switch rated for the application’s specific temperature range, whether high or low. |
| 8. What is the Switching Frequency? | Ensure the switch can handle the application’s required activation speed. | Choose a switch capable of withstanding high-frequency operations if necessary. |
