Catalog excerpts
UIR/M Incremental rotary encoders IRC520,521,523, 524 and 525 IRC520-5 is a manual incremental hand wheel with locking, dedicated for manual control and entering of information into control systems of CNC machines, where high mechanical endurance is requested for the locking mechanism and for high radial and axial loading on the output shaft. It is possible to place any control hand wheel on the output shaft with diameter of 10 mm. IRC520 - 5 with LED in the illuminator and in standard industrial configuration converts rotary movement of the shaft, which generates sequence of output signals. For division of 100 pulses, the signal 1 is at level H and signal 2 at level L in the locked position. Each position is locked. Other setting according to agreement with producer. IRC520 - 5 can be equipped by producer with a control hand wheel with scale. Assembly The encoders IRC520 - 5 are mounted to the respective equipment using three screws M4 on diameter of 42 mm or using a groove. Centering of the encoder is performed with fitted diameter 50h7. Connection should be of such design, that maximum permissible radial and axial load of the shaft are not exceeded. It is not recommended to place the encoder IRC520 - 5 with its shaft upward in wet environment with trickling or spraying fluid. Electrical connection can be done only with device switched off and at compliance with rules for handling with electrostatic sensitive equipment! When temperature is less then -5°C cable must be fixed. TECHNICAL DATA Electric data Maximum speed WORKING CONDITIONS Output signals of the encoders 2 basic signals (1,2) shifted 90° electrical 1 zero pulse (3) and their negations. The zero pulse is not guaranteed above 100 kHz.
