Miniature rotary encoders from Zettlex are ideally suited to space constrained geometries where the maximum outer diameter is <50mm and often <25mm.
Applications include motor encoders, servo controls, robot motion controls, azimuth and/or elevation angle measurement.
Zettlex miniature rotary encoders are particularly suited to applications that require high resolution and repeatability even in difficult physical environments.
Zettlex miniature rotary encoders typically comprise a passive, rotating target and a stationary antenna. The target can be attached to the shaft in a variety of ways including collar, grub-screw or adhesive bonded. Hollow shaft or end-of-shaft geometries are available. A Zettlex miniature rotary encoder requires no bearings or precision alignment of target and antenna. Targets typically weigh a few grams and so start up torque and moment of inertia are low.
