Atmosphere without aggessive substances. The incremental rotary encoders IRC with LED diode as the light source in the standard industrial version convert the rotation to two elektrical sinusoidal incremental signals (1 and 2) with bilateral shift by 90° with approximate amplitude of 1 V pp and one zero impulse (3) per one rotation with approximate amplitude of 0,5 V. They are designed for transmission of electrical information on alignment of two mechanical units, their angle shift or rotational movements. The encoder IRC is mostly used together with digital indication or control systems. They may be used in other devices requiring high accuracy and reliability of measurement and transmission of signal over long distances.

It is also possible to order interconnecting cable, opposite segment of the conector, cable plug and homokinetic connection (see the caloloque sheet „Accessories“). Example We would like to order 20 pcs IRC307/512 KA M. The encoder IRC307 with 512 impulses per one rotation and with a conector fitted on the axix, frost-proof, with delivery in three weeks time. Assembly The IRC 307 encoder is installed into appropriate equipment using 3xM4 screws or a groove. The position of the shaft is explicity determined by a fitted diameter of 50h7 mm. The IRC 317 encoder are installed using 3xM3 screws and the position of the shaft is explicitly determined by a diameter of 36f8. It is recommended to use appropriate hokinetic connections (see the cataloque sheet „Accessories“). The IRC 327 encoder are mounted on the shaft of the respective device and 2 imbus M4 screws. After the that sensor is to be turned to the required position and 4xM3 screws of the fixed plate connection are to be tightened. The connection has to be designed so as to avoid exceeding the maximum ad- missible radial or axial load applied to the shaft and it is necessary to keep the connection aligned. The cable of the IRC327 encoder must be fastened so as to avoid stress on the encoder by is own weight. Cosidering the electrostatic sensitive components used it is recommended to connect the encoder without power supply and to follow the work rules for electrostatic sensitive devices. In wet enviroments with running or splashing water it is recommended not to position the IRC 3x7 encoders with the shaft pointing upwards.

IRC30x – external diameter of the shaft ∅ 6 mm IRC31x – external diameter of the shaft ∅ 10 mm IRC32x – internal diameter of the shaft ∅ 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.

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 so as to avoid exceeding the maximum radial or axial shaft load permited. It is necessary to keep alignment connection. It is recommended to use suitable homokinetic diaphragm couplings [see Accessories catalogue list]. Considering that sensitive electrostatic parts have been used we rec- ommend to connect encoders without a power supply and to strictly follow the rules for work with electrostatic sensitive equipment. When temperature is less then –5°C cable must be fixed. Assembly – continued from previous page IRC300 - 305 IRC310 - 315 IRC320 - 325 How to order?
