Monitoring critical valve positioning

ifm fail-safe sensor can continuously monitor the position of a valve for safe operation. For example, the sensor can be setup to monitor the valve in a continuos closed position. If the valve opens, possibly leaking caustic solutions, the sensor will fail to safe and send a message to the safety relay to stop operation.

Monitoring high-speed doors

Fast-moving operations are typically enclosed and secured with a door. Here, the fail-safe sensor continuously monitors a metal target on a critical door. If the door opens by personnel attempting to access the hazardous location, the sensor will fail to safe. This interruption triggers a signal for reliable stoppage.

Detecting a critical part on a machine

A critical part on the undercarriage of a machine can be continuously monitored. If the critical part is damaged or missing, the fail-safe sensor will detect the change and fail to safe. Continuous monitoring helps protect the machine against damage.

Monitoring operation range of robots

Robotic arms used in industrial automation are typically located inside a protective cage to protect personnel working in close proximity to the robot. The robot is fitted with a metal target and ifm's fail-safe sensor is positioned near the robot's main axis to sense the target. The contact-free sensor continuously monitors the target to guard against unplanned robot travel which could potentially harm workers and equipment. If the robot moves into a danger zone or dangerous position, the sensor will fail to safe, stopping robot movement.
