IFM magnetic sensors provide reliable non-contact detection of position, movement and magnetic fields in industrial automation systems. The product range includes compact, full-metal, high-speed and pressure-resistant sensor designs for different machine requirements. Magnetic sensors are available with PNP, NPN and configurable switching outputs for flexible PLC integration. Depending on the model, they support applications ranging from hydraulic-cylinder position detection to hygienic food-processing equipment. Robust housings, high switching frequencies and advanced protection ratings enable dependable operation in demanding industrial environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
Magnetic sensors detect the presence and position of magnetic fields without requiring mechanical contact with the target. This principle enables reliable monitoring of moving components while reducing mechanical wear. Different sensing ranges and housing formats allow installation in compact as well as long-range applications. Sensors can be used for end-position, movement and machine-status detection. This makes magnetic sensing a practical solution for automated industrial equipment.
IFM magnetic sensors are available for general automation as well as specialised hydraulic-cylinder applications. Pressure-resistant versions can withstand high hydraulic pressures while monitoring piston position. Full-metal versions provide enhanced mechanical robustness for demanding industrial and hygienic environments. Compact versions are suitable for machine structures where installation space is limited. This broad product range supports different machine-design and environmental requirements.
Magnetic sensors are available with PNP, NPN and configurable output technologies. Depending on the model, switching functions can include normally open or normally closed operation. Many versions provide short-circuit and overload protection for reliable electrical operation. M8 and M12 connectors as well as cable versions simplify integration into machine wiring systems. High switching frequencies support fast-moving automation processes.
Selected IFM magnetic sensors use stainless-steel full-metal housings for demanding wet and hygienic applications. High ingress protection ratings such as IP67, IP68 and IP69K are available on suitable models. Food-processing and washdown applications can benefit from corrosion-resistant sensor construction. Temperature-resistant versions are available for elevated-temperature environments. These characteristics make magnetic sensors suitable for challenging production conditions.

Selection should be based on sensing distance, target magnet, electrical output and installation environment. Hydraulic applications may require pressure-resistant versions designed for cylinder installation. Food and beverage applications can benefit from stainless-steel full-metal designs with high ingress protection. High-speed machinery should use a sensor with an appropriate switching-frequency rating. Connector type, cable length, temperature range and mounting dimensions should also be considered during product selection.
Magnetic sensors should be positioned according to the specified sensing distance and reference magnet characteristics. Proper mechanical alignment helps maintain a stable switching point during machine movement. Threaded sensors can be secured using the appropriate lock nuts and specified tightening torque. Electrical connections should match the selected PNP, NPN or configurable output type. Regular inspection of the sensor body, connector and mounting position helps maintain reliable operation.
