Customer specific products
As we all know, the oldest magnetic sensor is the compass - using ferromagnetic parts, it detects the direction of the Earth's magnetic field. Hard drives for information storage are a modern use of magnetic sensors: miniaturised magnetic sensor elements detect the magnetisation of microscopically small regions in the storage layer of the hard drive. These two examples give you some idea of the wide variety of possible applications.
What makes magnetic sensors so universal in their application?
- Selectivity: parts and media that build up or change no magnetic field of their own are not detected.
- Speed: results can be measured down to the nanosecond range.
- Working temperature: -100 ... +200 ° C
- Resolution: measurement of the smallest magnetic fields, down to the nanotesla range
- Interference resistance: High EMC and ESD resistance
Based on expertise gathered over years in the area of sensor elements and magnetism, VS Sensorik also develops and fabricates customer-specific sensors. Examples are:
- 3D position sensor for robotic applications: Precise determination of the position of ferromagnetic switching marks through non-magnetic walls
- Distance sensors with a resolution in the micrometre range
- Absolute rotary encoders for speeds up to 60,000 rpm
- Pulse encoders for stoppage monitoring in machine tools
- Proximity switches for the detection of piston rings through the wall of the aluminium engine block
- Precision contact switches: Control of a flush connection of two metal parts
