heavy duty incremental shaft encoder


RENCO Encoders introduces the RHDi, heavy duty incremental shaft encoder. The RHDi has been developed utilizing the latest technology to meet the most demanding industrial applications. RENCO ASIC technologies allow the RHDi to bring new levels of performance and value to Machine Tool, Packaging, and similar heavy-duty industrial motion control applications. The RHDi uses precision bearings, metal code disks, proprietary custom LED illumination, and custom Opto-ASIC circuitry to significantly raise the bar for performance in this product category. It comes with a standard 2.6” square mounting flange, and can operate in temperature extremes from 100°C to -30°C. Typical applications include textile equipment, machine control, process control, oil field applications, industrial weighing, agricultural machinery, paper industry process control, etc. NEMA 3, 13 and IP54 requirements can be met when ordered with the shaft seal.
