Data Sheet AEDR-872x 3-Channel Reflective Incremental Encoder (Analog Output) Description Features The Broadcom AEDR-872x encoder is a three-channel Analog Output option: Two-channel differential analog output and with a digital index output optical encoder with two channels differential analog and a third digital index output. The encoder is designed to Surface mount leadless package: 3.95 mm (L) 3.4 mm (W) 0.9562 mm (H) operate over 40C to 85C temperature range and so is suitable for both commercial and industrial end applications. Operating voltage of 5.0 V supply Built-in LED current regulation, and so no external The encoder houses an LED light source and biasing resistor is needed photo-detecting circuitry in a single package. The small size 40C to 85C absolute operating temperature of 3.95 mm (L) 3.4 mm (W) 0.9562 mm (H) allows it to High encoding resolution: 318 (lines/inch, LPI) be used even in a wide range of miniature commercial applications in which size and space is a primary concern. Applications The AEDR-872x encoder, with two channels differential analog outputs (Sin, /Sin, Cos, /Cos) can be interfaced Ideal for high volume applications: directly with most of the external interpolators available. As Closed-loop stepper motors such, the encoder provides great design-in flexibility and Miniature motors easy integration into existing systems.
