Optical incremental encoder with heavy-duty double bearing construction. The internal code disc generates A/B phase pulse signals and Z zero mark pulse, which are transmitted to PLC or speed controller for rotor speed, direction and absolute index position calculation. Explosion-proof enclosure isolates internal electronic components from flammable gas atmosphere. The hollow shaft structure can be directly mounted on the rotating shaft of large machinery, and the terminal housing can be rotated 180 degrees for flexible wiring layout. Built-in robust mechanical structure withstands heavy radial and axial load, vibration and wide temperature fluctuation.
