Resolvers Types: Housed, Heavy Duty Housed, Industrial, Frameless Guide: Unlike rotary encoders, which use a coded disk to determine position and have a digital output, resolvers are magnetic devices that use two sets of rotating windings and a fixed core winding to generate an analog (sine and cosine) feedback output. Considered more rugged than encoders, they are used in adverse operating conditions involving extreme temperature, high shock and vibration, and dirty environments. Harowe brand resolvers are suited for high temperature (up to 220째C) applications and have outstanding mechanical shock and vibration specs. In addition, shielded, spacedsupport bearings provide up to 10x the life of duplex bearings. Tooth-wound models cut electrical error 50 percent, and brushless models eliminate components that can limit life.

Series 11 Housed Brushless Resolver Ideal mate for brushless servomotors. Brushless construction uses a rotary transformer to pass the reference signal to the rotor, eliminating components that can limit life and cause noise. Series 11 has excellent angular accuracy and repeatability. It is rated up to 155째C for high temperature applications. Size/Mounting: 1.1" diameter, servo Accuracy: + - 2 to + - 20 arc min.
