Sliding gate operator’s limit sensor – Spring mechanism

Sliding gate operator’s limit sensor – Spring mechanism

• Spring and Switch:

  The system includes a spring and a limit switch. The spring is typically mounted on a bracket or lever. 
• Gate Contact:

  As the gate moves, it pushes against the spring, compressing it. 
• Switch Activation:

  Once the gate reaches its limit (fully open or closed), the compressed spring activates the limit switch. 
• Motor Stop:

  The activated switch sends a signal to the gate operator’s control board, which then stops the motor. 

• Physical Mechanism: The spring mechanism is a physical, contact-based system. 
• Reliability: It provides a reliable way to define the gate’s travel limits. 
• Maintenance: Regular checks are needed to ensure the spring and switch are functioning correctly. 

• Simplicity: The spring mechanism is relatively simple and easy to understand. 
• Cost-Effective: It can be a more affordable option compared to some other limit switch systems. 

• Durability:

  The spring and switch mechanism can be more susceptible to wear and tear over time compared to magnetic systems. 
• Sensitivity:

  It can be more sensitive to impacts or obstructions, potentially leading to damage or misalignment. 
• Maintenance:

  It may require more frequent adjustments or replacements compared to magnetic systems. 

• Magnetic Limit Switches:

  Use magnets and reed switches to detect gate position, offering greater reliability and smoother operation.
• Spring Limit Switches:

  Rely on physical contact and force, which can be more prone to wear and tear.
