Operating Guidelines for GR01F

To preserve gripper lifespan, the gripping point "L" and arm length "H" must remain within specified limits relative to operating pressure. Graphs illustrate the relationship between gripping force, gripping point, and pressure for different bore sizes.

Ordering Codes and Sensor Recommendations

Ordering codes cover various bore sizes and configurations, including double-acting magnetic versions. Recommended sensors and adapters ensure compatibility and reliable position detection.
