As small as a finger: magnetic angle sensor fits into door hinges

The posirot^® PRAS1 sensor measures rotational positions from 0° to 360° using a Hall effect sensor array and an external position magnet. The magnetic encoder technology is completely contactless and contains no moving parts. PRAS1 sensors are therefore particularly shock and vibration resistant. The sensor housing is made of stainless steel. The protection class is IP67 with the option of IP69 when using the corresponding mating connector. Due to its robustness, the sensor is also suitable for use in applications with difficult ambient conditions such as packaging machines or filling plants. The IP69 version of the sensor is particularly suitable for applications with intensive cleaning processes in pharmaceutical and food production.

The measuring range of the sensor is 0-15° to 0-360° (in 15° steps). It is available in the output types 0.5…10 V, 0.5…4.5 V or 4…20 mA. The resolution of posirot^® PRAS1 is 0.03% (60… 360°) and 0.1% (15… 45°). It has a linearity of +/-0.3% of the measuring range. Alternatively the sensor is available with incremental or digital output (SSI).
