RSYN angular position sensors are non-contact transducers that incorporate proprietary rotor and coil designs. Their basic 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. Shock survival to 30g with an 11 ms half-sine form and vibration tolerance to 20g over 15 to 2000 Hz make these transducers the obvious choice where severe conditions are expected. RSYNs are also resistant to humidity and salt mist. Excellent performance over a temperature range of -67° to 221°F (-55° to 105 °C) provides a significant advantage over comparable rotary sensors. RSYN angular position sensors are compact. They are available in two sizes: the RSYN-8-30 which is 0.750 inches (19.05 mm) in diameter, and the RSYN-11-30 which is 1.06 inches ( 26.92 mm) in 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. The stator core is a lamination stack of highly permeable magnetic alloy material and the rotor is made of the same material. A very small air gap separates these components. This combination provides for an “all-iron” flux path that provides for very high efficiency resulting in a very high signal to noise ratio and a very low temperature coefficient of scale factor. The linear AC output represents the rotor shaft angle position providing the user with exceptional resolution even over very small angular ranges. Both models offer the flexibility of six output leads to provide for a variety of connection schemes. Both models are factory calibrated over ±30°. They may be over ranged to ±35°, a total of 70° if necessary.
