Magnetic Field Sensors

Magnetic field sensors are used, in particular, for the contactless detection of the piston position in pneumatic cylinders. We also offer application-specific sensor types for use in welding or Ex-areas as well as for analog position measuring. 

Magnetically actuated proximity sensors in cylindrical form enable large detection ranges of up to 90 mm such as for pig detection in pipelines. Thanks to maximum EMC immunity and protection class IP67, the sensors support high system availability.

NIMFE – Weld Nut Sensors Guarantee a Reject-free Production Process

The weld nut sensors detect applied weld nuts thanks to the sensor integrated in the locating pin. In addition to spacer and reinforcing sleeves, the automotive industry often employs weld nuts to connect plates. The presence of these parts must be monitored to guarantee a smooth production process that is free from rejects. Turck's weld nut sensors not only detect metal, but also replace the locating pins at the same time.

Reliable icon

Proven technology, optimal materials and sensor models tailored to the application reliably detect the presence of weld nuts.

Weld-resistant materials protect the sensor in the harsh production environment and enable smooth integration into the existing application.

BIM – Magnetic Field Sensors for All Common Pneumatic Cylinders

Thanks to a permanently reliable operating principle, Turck magnetic field sensors detect permanent magnets of various strengths positioned on the piston. The BIM series consists of universal magnetic field sensors for all common pneumatic cylinder shapes.

Compact icon

With a housing length of 19.7 mm, the BIM-UNTK is one of the most compact magnetic field sensors on the market and is therefore especially useful in short-stroke cylinders.

Easy mounting icon

BIM-UNT and BIM-UNTK both feature a fixing lip. The sensors can be mounted in the field effortlessly, without the need for additional tools.

Stable mounting icon

A special screw with special tool steel alloy secures the device in the groove. This ensures stable sensor mounting.

All around visible LED icon

The bright all-around LED is clearly visible from all sides, ensuring that the current switching status is always seen perfectly from any angle.

NIMFE in Automotive Production

Reliable: Turck weld nut sensors can withstand harsh conditions

Mounting of BIM Sensors

Perfect fit: Compact magnetic field sensors from Turck are instantly mounted

Best Practice

Compact Monitoring Devices: Magnetic Field Sensors Monitor Cover Hinges

Wilhelm Niemann Maschinenfabrik from Lower Saxony guarantees reliable operation of your machines with fast interface devices and precision sensors from Turck. The company opts for BIM-UNT magnetic field sensors to monitor cover hinges.

Detection and Fixing

With their construction-related two-in-one solution, NIMFE weld nut sensors are a reliable alternative to optical measurement methods: the nuts are detected inductively and fixed at the same time. This facilitates production processes within bodywork construction.
