Key specifications
Contact configuration: 1NC+1NO
Housing material: Metal
Reset mechanism: Manual red reset

How to use
Installation involves mounting the switch securely to a stable structure and routing the safety cable along the machinery or conveyor system. Ensure the cable is properly tensioned according to the manufacturer's guidelines to allow for immediate activation when pulled. Once the switch is triggered, the circuit is interrupted, and the device remains in the locked position. To resume operation, the operator must manually press the red reset button after the emergency condition has been cleared and the cable tension is restored.
What to consider before purchase
Ensure the cable length matches the requirements of your machinery layout
Verify that the contact configuration is compatible with your existing safety relay or control system
Check that the mounting location allows for easy access to the manual reset button
Usage recommendations
Regularly inspect the cable tension and the integrity of the metal housing to ensure the switch remains fully operational. Perform periodic functional tests to verify that the emergency stop signal is correctly transmitted to the control system.
