Extremely rugged solution for main drives

The incremental encoders FGH 14 for continuous hollow shafts up to Ø 150 mm are mostly mounted 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. The maintenance-friendly replacement scanning head facilitates simple changeover without separating the motor and gearing.
