Incremental rotary encoder RHI90N

The hollow shaft encoder RHI90 is a product, which has been developed specially for mechanical drive and lift engineering. It combines the advantages of modern technics and cost effective design.

The hollow shaft encoder is available with shaft diameters between Ø16 mm and Ø45 mm. Thanks to its comparatively small outside diameter it can also be used if only little mounting space is available. The shaft fastening is designed in a way that the shaft of the customer is not being damaged.
