SMRI is the bearingless incremental encoder tailored to meet the high speed requirements of rotary motion systems in advanced applications. In addition, the robust space-saving construction and encapsulated electronics guarantee high IP67 protection (IP69K on demand) and make it ideally suited for motor feedback in harsh environments and heavy-duty applications such as torque motors and synchronous generators in direct drive wind turbines and even for direct installation in large diameter shafts up to 380 mm (15”). Furthermore it can be installed in rotary applications up to 25,000 RPM such as in machine tool spindle motors. The two separate component design without integral bearings along with the dependable magnetic scanning increases benefits in comparison with high-priced optical devices. SMRI is non-contact, wear-free and immune to dirt and contaminants, thus it offers virtually maintenance-free enduring service even in the most demanding conditions and under moisture, vibrations and significant mechanical stresses and forces. In addition, the magnetic system affords large mounting tolerances and enables a gap between the sensor head and the magnetic ring up to 2 mm (0.079”); this allows for much greater ease of installation than optical sensors and dependable operation even though alignment and parallelism are rough. Furthermore SMRI features a very compact and slim profile and is designed to save space and ease integration thanks to the minimum scanning head foot-print and shallow ring (10-mm / 0.39” depth only). So it can be installed directly in a wide range of motor shafts and even when the space is constricted. SMRI is offered in both 2-mm and 5-mm pole pitch options. It generates square wave signals (AB0, /AB0) with Push-Pull or Line Driver output circuits and cable or M12 connector outlets. A wide variety of custom ring diameters and resolutions (up to 180,000 PPR) is available on request. As an additional advantage, it can be equipped with a built-in sensor to provide the 0 Reference signal once per revolution. Furthrmore it is fitted with integral LEDs to give diagnostic information (activity and status/error) and ease at commissioning.
