Measuring wheel encoders
Pulses per revolution 1,024 Resolution in pulses/mm 3.41 Pulses/mm 1) Measuring increment (resolution in mm/pulse) 0.3 mm/pulse 2) Measuring step deviation ± 0.008° 3) Error limits ± 4 mm/m, subject to measuring wheel (measuring wheel surface + measuring surface + ambient conditions) Initialization time 30 ms
- 1) Calculation example: Pulses per revolution / measuring wheel circumference = 16,384 pulses per revolution / 200 mm = 81.92 pulses/mm.
- 2) Calculation example: Circumference of wheel / pulses per revolution = 200 mm / 16384 pulses per revolution = 0,012mm/pulse.
- 3) Value refers to the mounted encoder.

- 1) The surface of a measuring wheel is subject to wear. This depends on contact pressure, acceleration behavior in the application, traversing speed, measurement surface, mechanical alignment of the measuring wheel, temperature, and ambient conditions. We recommend you regularly check the condition of the measuring wheel and replace as required.
- 2) Allow for self-heating of 3.3 K per 1,000 rpm when designing the operating temperature range.
