Product Description:

The RI64/1024B04FDIBB00 is manufactured by Danaher and belongs to the Dynapar series. This encoder functions as an incremental optical encoder for industrial automation needs. The number of encoder pulses spans between 1 and 2540 pulses throughout one revolution. This model features an optional index signal and 2 channels quadrature output.

The RI64/1024B04FDIBB00 encoder operates with A leading B phase sequencing when rotating in a counter-clockwise direction. The output selection can be performed based on which format users require. The electrical output phase of the encoder extends from 90 degrees through 22.5 degrees of variation on either side. This encoder RI64/1024B04FDIBB00 requires 5 to 26 VDC input voltage. The current requirement for this model is 80Ma. The RI64/1024B04FDIBB00 encoder allows customers to choose from four different output configurations. The device features a 7273 open collector which enables 40 mA sinking power. The output of the encoder utilizes 7272 polarized drivers to produce 40 mA shores or 40 mA sources. The line driver section presents customers with two differential options for selection. The standard operating condition allows a minimum frequency response measurement of 100 kHz. At high temperature the index output responds at 75 kHz frequency.

The device operates at 10,000 RPM when set to resolutions below 1024 PPR. The device speed limit drops to 5000 RPM after applying higher resolution settings. The available shaft dimensions consist of 10 mm and 1/4 inch followed by 3/8 inch sizes. The maximum shaft loading capacity for 1024 PPR and lower ranges to 80 pounds. If the resolution exceeds 1024 PPR then the allowed shaft loading becomes 40 pounds. The starting torque of this encoder is 0.007 Nm, allowing for 0.014 Nm if you install a shaft seal.
