Dimensions in mm Ball bearing Sleeve bushing Note: Internally, the PBA12 contains a small magnet. This also generates a weak magnetic field outside of the sensor, which may influence neighbouring sensors. If the distance between two PBA12s is less than 25 mm (distance between axes), magnetic shielding (e.g. an iron plate) must be installed between both sensors.
