Suitable for

• Monitoring travel limits of conveyor belts
• Detecting the position of robotic arms
• Safety interlocks on industrial machine guards
• Automated assembly line positioning tasks

When it may not be suitable

This device is not intended for use in explosive atmospheres or environments with extreme chemical exposure unless specifically rated for such conditions. It is also not suitable for applications requiring high-speed switching beyond its mechanical frequency limits or in environments where the physical dimensions of the switch exceed the available mounting space.

Key specifications

• Contact configuration: 1NC/1NO
• Switching mechanism: Snap action
• Actuator type: Roller lever with spring return
• Application: Industrial automation and control

How to use

The switch should be mounted securely to a stable surface using the provided mounting points, ensuring the roller lever is positioned to make contact with the moving part at the desired trigger point. Wiring should be performed according to the terminal markings for the 1NC/1NO configuration. Ensure that the mechanical travel of the actuator does not exceed the specified limits to prevent damage to the internal mechanism.

What to consider before purchase

• Verify the physical space available for mounting the switch
• Ensure the electrical load is within the rated capacity of the contacts
• Check the environmental conditions of the installation site
• Confirm the compatibility of the roller lever with the moving machine part

Usage recommendations

Regularly inspect the actuator for signs of mechanical wear and ensure that the mounting hardware remains tight to maintain accurate switching points throughout the operational life of the device.
