Broadcom AEDR-9830DP Optical Encoders are three-channel reflective incremental encoders with analog or digital differential output (318 LPI). These encoders can be configured to produce analog or digital outputs using reflective technology for motion control purposes. The selectable options are two channels differential analog with a third-channel differential digital or analog index output or three-channel digital differential A, B, and I output. The AEDR-9830DP encoders are designed to operate over a -40°C to 115°C temperature range. These encoders come in small sizes of 4mm (L) x 4mm (W) x 0.73mm (H). This small size allows encoders to be used in various miniature commercial applications. The AEDR-9830DP encoders house an infrared LED light source and photodetecting circuitry in a single package. These optical encoders are suitable for closed-loop stepper motors, actuators, industrial printers, robotics, card readers, Pan-Tilt-Zoom (PTZ) cameras, portable medical equipment, optometric equipment, and linear stages.
