Incremental rotary encoders IRC300 - 325 IRC30x - external diameter of the shaft 0 6 mm IRC31x - external diameter of the shaft 010 mm IRC32x - internal diameter of the shaft 0 12 mm The incremental rotary encoders IRC with a LED as the light source in the standard industrial version converts rotary motion to electrical signals by the photoelectronic scanning of rasters onto two glass elements [stator and rotor]. Electrical signals provide information of bilateral position of two mechanical parts, angle turn or rotary motion. Common use of the IRC encoders is in connection with display units or numerical control systems on machine tools or robots. They are excellent for application in other equipment where measuring accuracy and reliability are required.

Description of connection elements IRC300 * 325 Note: Function Sensor is used with a supply resource enabling balancing the decrease of voltage on the cable as the feedback. If Sensor function is not used we recommend to connect PIN 2 to PIN 12 and PIN 10 to PIN 11. Assembly - continued from previous page mined by fitted diameter 36f8. Encoders IRC320-325 are installed on the shaft of the appropriate equipment and tightened with 2 imbus screws M4. Afterwards the encoder is turned to the required position and 4 screws M3 are tightened with stationary couplings. The connection has to be...
