Zettlex Ltd.




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.
