Leine Linde 729798-01 Heavy-duty Hollow Shaft Encoder

Description

The 729798-01 is part of the Type XHI series and is manufactured on the proven Model 861 platform, which has been widely used in industrial motion control applications requiring durability and precision. It is supplied with a Ø16 mm blind hollow shaft, allowing direct installation on compatible motor shafts or driven equipment while minimizing additional mechanical components. The 86 flange configuration supports straightforward integration with a broad range of industrial machinery.  The 729798-01 is intended for these conditions by combining a rugged mechanical structure with an insulated shaft design that helps reduce bearing current issues and unnecessary wear. This makes it well suited for equipment operating in steel production, mining, paper manufacturing, marine systems, and other heavy industrial processes where reliability is essential and unexpected downtime can interrupt production. The 729798-01 operates from a 9–30 VDC power supply and provides HTL output signals, delivering reliable digital pulse transmission in installations with long cable runs or electrically noisy environments. Electrical connection is made through a radial cable outlet fitted with an M20 cable gland for Ø8–11 mm cables, providing secure cable routing and dependable sealing. The encoder supports six output channels, allowing incremental position feedback together with complementary signals for improved transmission reliability. For applications requiring additional condition monitoring, an Advanced Diagnostic System is available as an option, enabling encoder status monitoring and predictive maintenance to help reduce unplanned equipment stoppages.
