How to choose Rotary encoders

Points to check when selecting, with the values for this product (SKF Steering Encoder Unit).

  1. 1. Select pulse count based on required angular resolution

    This product: Resolution (pulse count) 64 パルス/回転

    The number of pulses per revolution determines the smallest detectable angle. Listed products have a relatively low count of 32 to 80 pulses/rev, suited to motor speed control and steering detection. Counting both edges of A and B phases (4x multiplication) quadruples the effective resolution, so confirm the required value together with the processing method of the controller.

  2. 2. Allow margin in maximum rotational speed

    This product: Maximum Rotational Speed 300 r/min

    The maximum rotational speed of listed products ranges widely from 300 to 14000 r/min. Confirm that the application's top speed has sufficient margin. Also confirm that the output frequency, determined by rotational speed multiplied by pulse count, falls within the input frequency capability of the receiving-side counter.

  3. 3. Select a bearing unit with bore matching the shaft diameter

    For bearing-integrated types, the bore must match the diameter of the mounting shaft. Listed products have bores of 15 to 45 mm, with sizes divided by shaft diameter. Check the fit tolerance and axial positioning method against the drawings, assuming use as a bearing.

  4. 4. Check mounting space by outer diameter and mass

    Outer diameters range from 35 to 85 mm, and masses from 0.07 to 0.53 kg. Check interference with the motor housing or pulley interior, including the cable exit direction. When mounting on a rotating body, consider the effect of mass on inertia and vibration.

  5. 5. Match supply voltage to the control circuit

    This product: Power supply voltage 5~12 V DC

    Listed products operate on a supply voltage of 5 to 12 V DC. Confirm that it matches the available power supply, and that the output signal voltage level and output circuit type meet the input specifications of the receiving side. For automotive applications, also confirm tolerance to supply voltage fluctuations.

  6. 6. Verify phase difference, duty ratio, and cycle accuracy

    This product: Periodic accuracy ±4 %

    Large variations in the phase difference between A and B phases (normally 90°), duty ratio, or cycle accuracy can cause direction determination errors and speed detection fluctuations. For high-precision speed control, check in the specifications that these tolerances meet the control requirements.
