HEDS-9940EVB

HEDS-9940EVB is an AEDR-9940 evaluation board with 2 units of code wheel, multiple optical radius 256, 400, 512, 720 CPR base. The AEDR-9940 is a three-channel reflective optical encoder. Selectable and programmable options are available for three-channel digital or analogue differential A, B, and I output. The AEDR-9940 in analogue encoder modes, with three channel differential analogue outputs (Sine+, Sine-; Cos+, Cos-; I+, I-), can be interfaced directly with external interpolators available. The AEDR-9940 digital encoder mode offers two-channel (AB) quadrature digital outputs and a third channel digital index outputs. Suitable for Closed-loop stepper motors, small motors, actuators, industrial printers, robotics, card readers, PTZ camera, portable medical equipment, optometric equipment, linear stages applications.

• AEDR-9940: operating voltage of 3.3V and 5.0V supply
