Hot selling RSYN 11-30 rotary variable differential transformer angular displacement sensor quality assurance

Product Descriptions

The RSYN Series are RVDT (Rotary Variable Differential Transformer) angular position sensors that incorporate proprietary rotor and coil 

designs. Their 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.

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 sensitivity. 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 lead wires to provide for a variety of 

connection schemes to signal conditioners. The RSYNs are factory calibrated over ±30 degrees, but may be over-ranged to ±35 degrees for a 

total sensing range of 70 degrees if necessary (with somewhat increased non-linearity).
