SP INTERNATIONAL Piher Sensing Systems PST-360 contactless position/angle sensor combines a through-shaft design with 360º absolute position feedback in a thin package. Device is used for measuring angles between 30° and 360°. Key features include through hole sensing where the shaft passes directly through the sensor, high accuracy absolute position feedback over 360°, and a true non-contacting sensing element. Sensor incorporates a proprietary ring magnet with hall chip for the sensor element.  This combination does not rely on gears or other rotating parts, maximizing robustness and sensing accuracy.  The proprietary design provides a streamlined sensor with only one moving part along with electronics designed for harsh environments.
