Resolution selected via adjustable DIP switch, pre-set to 2048 PPR. All resolutions are listed as pre-quadrature, meaning the final number of counts is PPR x 4. 2. Some stepper motors may leak a magnetic field causing the AMT index pulse to not function properly (non-magnetic version available with 8 pulses per revolution). cuidevices.comAdditional Resources: Product Page CUI Devices SERIES: AMT10 DESCRIPTION: MODULAR INCREMENTAL ENCODER date 08/04/2021 page 2 of 8 MECHANICAL parameter conditions/description min typ max units motor shaft length 9 mm motor shaft tolerance NOM +0/-0.015 mm AMT102 20.5 g weight AMT103 14.0 g axial play 0.3 mm 192, 384, 400, 500, 800, 1000, 1024, 2048 7500 RPM rotational speed (at each resolution) 48, 96, 100, 125, 200, 250, 256, 512 15000 RPM ENVIRONMENTAL parameter conditions/description min typ max units 1 operating temperature -40 100 C humidity non-condensing 95 % vibration 20~500 Hz, 1 hour on each XYZ 10 G shock 11 ms, XYZ direction 50 G RoHS 2011/65/EU Note: 1. Encoders with operating temperature of -40~125C are available as a custom order WAVEFORMS Figure 1 Quadrature signals with index showing counter-clockwise rotation I X A T S S S S P B The following parameters are defined by the resolution selected for each encoder. The encoders resolution is listed as Pulses Per Revolution (PPR), which is the number of periods (or high pulses) over the encoders revolution. Parameter Description Expression Units Notes This is the user selected value and the PPR resolution Pulses Per Revolution format all resolutions are listed in This is the number of quadrature counts CPR counts PPR x 4 Counts Per Revolution the encoder has T period 360/R mechanical degrees P pulse width T/2 mechanical degrees S A/B state width T/4 mechanical degrees This is the width of a quadrature state The width of a once per turn index is the I index width T/4 mechanical degrees state width for A & B lines Note: For more information regarding PPR, CPR, or LPR (Lines Per Revolution) view
