Product Overview
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 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 a virtually unlimited mechanical life due to the separation of electronics and the target. The arc design facilitates simple and fast assembly and calibration, contributing to cost savings during production. Key advantages include immunity to magnetic stray fields, a compact and low-profile package, and a touchless operation that eliminates wear and tear. These sensors are fully customizable to meet specific requirements, including mechanical design, programmable transfer functions, switch outputs, and various output protocols.
