Extremely rugged solution for main drives
The incremental encoders FGH 8 for continuous hollow shafts up to Ø 80 mm are mostly mounted on the unused shaft end by means of an isolated adapter flange or directly onto the shaft. Thanks to the flat design they are ideally suitable for attaching further sensors such as speed switches, absolute encoders or combinations of these. Furthermore, there is also the option of a redundant configuration with two equal scanning systems and evaluation electronics. That increases safety or facilitates the provision of separate signals to the motor controls and a higher-level controller.
