- Weld-slag resistant PUR cable with drag chain suitability - Nut with special weld-slag resistant coating - Mechanical end stop to protect the O-ring from destruction - Nut secured against shock and vibration due to saw tooth contoured vibration protection - LEDs clearly visible even in cases of high light exposure ifm's ecolink series comprises sockets, cable plugs and jumper cables as M8 and M12 versions. Even when fastened by hand, a perfect lasting seal of sensor, actuator and splitter connections is guaranteed. The integrated end stop protects the O-ring against destruction caused by over-tightening the nut. Even in harsh industrial environments, the connectors are protected against unintended loosening by a special vibration protection. Some types are fitted with highly visible LEDs for operation and switching status indication. The products of the ecolink EVW series for use in welding applications have a special PUR-jacketed cable. The non-stick coating of the coupling nut allows weld spatter to roll off the sensor and enables easy and quick cleaning.
