The rugged encoders

The incremental encoders FG 2 (solid shaft) and FGHJ 2 (hollow shaft) ensure the speed of standard, auxiliary and secondary drives is reliably measured. When attaching with an insulated coupling (solid shaft) or an insulating hybrid bearing (hollow shaft) they protect the drivetrain against damaging shaft currents. Short-term availability and additional options ensure they can be deployed in a wide variety of applications and are also suitable as simple replacement solutions for encoders supplied by third-party manufacturers. The axial terminal boxes offer sufficient space for straightforward wiring. The plug-in connectors are vibration-proof by design to ensure these are permanently secure even under extreme conditions.
