The sensor's non-contact electrical construction eliminates items such as slip rings, rotor windings, contact brushes or wipers that degrade over time and impair reliability. At the same time the coil design achieves extraordinarily high output and low noise. RSYNs offer enhanced tolerance to shock and vibration, as well as humidity & salt mist resistance, which make these transducers the obvious choice where severe conditions are expected. Excellent performance over a wide temperature range provides a significant advantage over comparable sensors. RSYN angular position sensors are also compact. They are available in two sizes: The RSYN 8-30 with a 0.75 inch [19mm] diameter, and the RSYN 11-30 with a 1.06 inch [27mm] diameter. The coil design comprises a primary and two secondary windings all placed in the stator. There are no windings in the rotor. The secondary windings act as pickup coils detecting the flux change caused by rotation of the rotor.
