Product catalog summary
Working Conditions: The IRC300-325 incremental rotary encoders operate under specific conditions: vibration resistance up to 10 gn (10 ÷ 2000 Hz), shock resistance of 50 gn (100 ms), and a standard operating temperature range of 0° to +60°C, with model M extending to -25°C. They can handle relative humidity up to 95% and absolute humidity up to 40 g.m-3, in non-aggressive atmospheres.
Output Signals: These encoders provide two basic signals shifted by 90° electric, one zero impulse, and their negations. Zero pulse reliability is not guaranteed above 100kHz. Shaft diameters vary: IRC30x (6 mm), IRC31x (10 mm), and IRC32x (12 mm).
Technical Data: The encoders support a rotation speed of 10000 min-1 and angular acceleration of 40000 rad.s-2. They have a moment of inertia of 20 g.cm-2 ±10%, with axial and radial shaft load limits of 20/40 N and 50/60 N respectively. They are protected to IP65 standards and weigh a maximum of 0.35 kg.
Assembly: Installation involves securing the encoders with screws (M4 or M3 depending on the model) and ensuring proper alignment to avoid exceeding shaft load limits. Electrostatic precautions are advised during installation.
Electrical Data: Supply voltage ranges from 10-30V or 5±5%, with a maximum supply current of 50/30V or 100 mA. Output frequency varies from 100 to 200 kHz, and output current is ±25 mA or ±20 mA depending on the model.
Type Identification: The encoders are identified by outlet type, shaft diameter, and encoder type, with options for frost resistance and optical zero impulse indication. Impulse counts per rotation range from 100 to 6000.
Connection Elements: The encoders use a specific pin configuration for signal and power connections, with recommendations for sensor function and electrostatic discharge precautions.
Ordering Information: Orders should specify encoder type, impulse count, outlet type, quantity, delivery terms, and any non-standard features. Accessories like connecting cables and couplings are available.

Incremental rotary encoders IRC300 – 325-1

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.

Incremental rotary encoders IRC300 – 325-2

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 constructed...
