Optical encoders for standard drives
The incremental optical encoders FG 2 (solid shaft) and FGHJ 2 (hollow shaf) ensure the speed of standard, auxiliary and secondary drives is reliably measured. When attaching the optical encoder with an isolated coupling (solid shaft) or an isolating hybrid bearing (hollow shaft) they protect the drivetrain against damaging shaft currents. Short-term availability and additional options ensure that the optical encoders 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.
