Product Overview
The Piher Sensing Systems PSAI Inductive Arc Position Sensors are engineered for demanding heavy-duty applications like tractors, excavators, and loaders. These sensors utilize inductive technology, detecting the position of a solid metallic target without relying on magnets, allowing for seamless integration into existing machinery. Their robust design features IP67 and IP69K sealing, high temperature tolerance, and an arc configuration for simplified assembly and calibration, leading to cost savings. The touchless operation ensures virtually unlimited mechanical life, free from wear and tear. These sensors are also immune to magnetic stray fields and offer fully customizable options for mechanical design, transfer functions, switch outputs, and communication protocols.
