As demand for functionally safe equipment products grows, so does Heidenhain’s component product offerings. New to the market are Heidenhain’s ROx 400 absolute rotary encoders, available in a functionally safe design including a mechanical fault exclusion for the shaft. Both the synchro and clamping flange versions passed testing from TÜV Süd, an international service corporation focusing on consulting, testing, certification, and training.
The ROx 400 encoders are available with a 6 or 10-mm shaft, and equipped with a machined flat to facilitate a positive lock during mounting. A functionally safe mounting scenario requires securing the mounting flange using M4 screws coated with a materially bonding anti-rotation lock adhesive. Additional specifications for mounting and operation must be followed to ensure the encoder meets the prescribed PFHd values from the product information. This additional information for mechanical fault exclusions is available as a supplement to the standard mounting instruction. This document describes things such as required materials for mounting surfaces, proper torque values, acceleration restrictions, as well as storage information.
