PHOTOELECTRIC ROTARY ENCODER Analog output signals ELECTRICAL DATA Power supply Light source Incremental signals Reference signal Photoelectric modular rotary encoder A75M is a wider diameter incremental encoder than A42M, as it is the main difference between these two open-type encoders. Maximum operating frequency +5 V ± 5%/ < 120 mA LED Differential sine +A/-A and +B/-B Amplitude at 120 Q load: - A = 0.6-1.2 V -B = 0.6-1,2V One quasi-triangular +R and its complimentary -R per revolution. Signal magnitude at 120 Q load: -R = 0.2...0.8V (usable) (-3 dB) > 180 kHz +5 V ± 5%/ < 120 mA LED Differential square-wave U1/U1 and U2/U2. Signal levels at 20 mA load current: - low (logic "0" ) < 0.5 V - high (logic " 1") > 2.4 V One differential square-wave U0/U0 per revolution. Signal levels at 20 mA load current: - low (logic "0") < 0.5 V - high (logic " 1") > 2.4 V (160 x k) kHz, k - interpolation factor +B lags +A for clockwise rotation (viewed from shaft side) U2 lags U1 for clockwise rotation (viewed from shaft side) Maximum rise and fall time Recommended max. cable length to subsequent electronics Output signals MOUNTING DIMENSIONS MECHANICAL DATA Line number on disc (z) Number of output pulses per revolution for A75M-F Max. permissible mechanical rotation speed 16000 rpm Protection (IEC 529) Max. weight Operating temperature Storage temperature Accuracy (T1 period of lines on disc in arc. sec.)
