MOUNTING PANEL RECOMMENDATIONS
FOR PANEL SEAL VERSION:
1. Panel thickness should not exceed 0.157".
2. Mounting hole diameter to be per recommended
dimensions.
3. 0.470" X 0.020" counter bore required for proper
sealing.
4. Anti-rotation feature is recommended. Feature
should be designed to lock into bushing keyway.

Seal:
* Grayhill recommends the use of a shaft seal for non-detented encoders to prevent inadvertant code output changes due to
the lack of detent.
