Technology Small Rotary
Zettlex rotary sensors 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 devices are particularly suitable to those applications that require high resolution and repeatability even in difficult physical environments.
Zettlex rotary sensors 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 geoemetries are available. A Zettlex sensor requires no bearings or precision alignment of target and antenna. Targets typically weigh a few gramms and so start up torque and moment of inertia are low. Axial distance is typically <10mm and can be <3mm.
