Honeywell Hawk™ 3-Inch Series Resolvers, dual speed (1X and 16X), 3.00 in OD, pancake simple housed with transformer configuration, 7 V, 2500 Hz, leadwire, no bolt pattern, sleeve mounting type, 0.25 transformation ratio, ±25 arcsec accuracy, stainless steel hub and housing For manufacturers who need an accurate, reliable, repeatable and durable rotary and angle absolute position sensor for potential use in defense, aerospace, medical and industrial applications. Honeywell Hawk™ Resolvers provide 360° noncontact, angular position sensing and enhanced accuracy (±7 arcmin) for precise motion control. Resolvers convert mechanical shaft position to an electrical signal which represents the actual shaft angle. They are variable transformers in which the stator has two phase windings mechanically displaced by 90°. The output consists of two sine waves that are phase shifted by 90°. Resolvers are typically chosen over electronic sensors (i.e., optical encoders, potentiometers, magnetic encoders/sensors) because they do not contain electronics, so they are not susceptible to performance fluctuations in harsh environments. Resolvers are inherently radiation hardened and offer durable EMC (Electromagnetic Compatibility) performance.
