Technology Large Rotary
Zettlex rotary sensors are ideally suited to geometries where either a larger shaft must be passed through the centre of the sensor or extreme levels of accuarcy are required.
Applications include CNC machine tools, rotary tables, test equipment, 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 dimensions are typically <10mm and often <3mm.
