A Position Control Milestone – Hollow-Shaft Kit Encoders with World’s First Maintenance-Free Multi-Turn Measurement Range
POSITAL has introduced a new series of absolute rotary encoders designed for applications requiring a hollow center form factor. Weighing just 110 g, with an outer diameter of 80 mm and 30 or 50 mm center openings, these devices are easy to integrated into servomotors, drives or the joints of robot arms. Their shape leaves room for drive shafts, mechanical components, cables or pneumatic/ hydraulic lines.
These new encoders mark a significant step forward for industrial motion control. Until now, most through- or hollow-shaft encoders have been limited to a single turn measurement range. POSITAL has overcome this limitation with an integrated rotation counter that reliably records each revolution the instrument experiences, even if these occur when system power is unavailable. The counter circuitry is powered by POSITAL’s well-proven, zero-maintenance Wiegand energy harvesting system, eliminating the need for troublesome backup batteries or complex mechanical solutions.
These new products are based on a capacitive measurement system and offer excellent accuracy (+/- 0.02 °) and dynamic response (up to 6000 RPM). With capacitance averaged around the circumference of the disks, these devices are tolerant of minor alignment errors and to the dust and moisture. Installation is straightforward: a few simple steps and the measuring system is ready for use. SSI and BiSS C interfaces provide a reliable, non-proprietary communications systems with no license fees.
