Product Overview
The Piher Sensing Systems PSAI Inductive Arc Position Sensors are engineered for demanding heavy-duty applications, including 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 design ensures excellent accuracy, IP67 and IP69K sealing, and high temperature tolerance, making them ideal for harsh off-highway environments. The arc design facilitates simple and fast assembly and calibration, leading to cost savings in production. Key advantages include a virtually unlimited mechanical life due to the separation of electronics and target, immunity to magnetic stray fields, and a touchless operation free from wear and tear. The sensors are available in a compact and low-profile package, adaptable to specific requirements with customizable mechanical designs, programmable transfer functions, switch outputs, and various output protocols and redundancy levels.
