70° C to 100° C
Input Current ............ 100 mA max with no output load
Input Ripple .............. 100 mV peak-to-peak at 0 to 100 kHz
Output Format.......... Incremental- Two square waves in
quadrature with channel A leading B for
clockwise shaft rotation, as viewed from
the encoder mounting face.
See Waveform Diagrams.
Output Types............Open Collector- 100 mA max per channel
Pull-Up- 100 mA max per channel
Push-Pull- 20 mA max per channel
Line Driver- 20 mA max per channel
(Meets RS 422 at 5 VDC supply)
Index ......................... Occurs once per revolution. The index for
units >3000 CPR is 90° gated to Outputs A
and B. See Waveform Diagrams.
Max Frequency ........Up to 1 MHz
Noise Immunity ........ Tested to BS EN61000-4-2; IEC801-3;
BS EN61000-4-4; DDENV 50141;

Min Edge Sep ........... 1 to 6000 CPR: 67.5° electrical at
100 kHz output
6001 to 20,480 CPR: 54° electrical
>20,480 CPR: 50° electrical
Rise Time .................. Less than 1 microsecond
Accuracy .................... Instrument and Quadrature Error: For 200
to 1999 CPR, 0.017° mechanical (1.0 arc
minutes) from one cycle to any other cycle.
For 2000 to 3000 CPR, 0.01° mechanical
(0.6 arc minutes) from one cycle to any
other cycle. Interpolation error (units >
3000 CPR only) within 0.005° mechanical.
(Total Optical Encoder Error = Instrument +
Quadrature + Interpolation)
