Amphenol Piher PSAI Position Sensors

Amphenol Piher Sensing Inductive Arc (PSAI) Position Sensors are for heavy-duty applications and are used to detect the position of a solid metallic target without depending on magnets. As a result, these sensors can easily be integrated into the existing machinery structure. In addition to the sensors’ high accuracy, IP67 and IP69K sealing and high-temperature tolerance make these absolute position sensors an excellent choice for harsh environments typically found in off-highway applications. The PSAI sensors’ arc design enables simple, fast assembly and calibration at the manufacturing line. Amphenol Piher Sensing Inductive Arc Position Sensors applications include tractors, excavators, and loaders.
