Standard cable is 24 AWG conductors with foil and braid shield.
Input Voltage ............ 4.75 to 28 VDC max for temperatures
up to 70° C
4.75 to 24 VDC for temperatures
between 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 ........100 kHz std; Up to 1 MHz optional.
(See Ordering Guide for availability)
Noise Immunity........ Tested to BS EN61000-4-2; IEC801-3;
BS EN61000-4-4; DDENV 50141; DDENV
50204; BS EN55022 (with European
compliance option); BS EN61000-6-2;
BS EN50081-2
Symmetry ................. 1 to 6000 CPR: 180° (±18°) electrical at
100 kHz output
6001 to 20,480 CPR: 180° (±36°) electrical
Quad Phasing ...........1 to 6000 CPR: 90° (±22.5°) electrical at
100 kHz output
6001 to 20,480 CPR: 90° (±36°)
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)
Max Speed ...............7500 RPM. Higher shaft speeds may be
achievable, contact Customer Service.
Shaft Rotation ..........Bi-directional
Radial Shaft Load ..... 5 lb
Axial Shaft Load .......3 lb
Starting Torque ........0.14 oz-in typical
