Broadcom AEDR-8500-102

The AEDR-850X encoder is the smallest 3 channels optical encoder with digital outputs in the market employing reflective technology for motion control purposes. The encoder is designed to operate over -20℃ to 85℃ temperature range and hence suitable for both commercial and even industrial end applications. The encoder houses an LED light source and a photodetecting circuitry in a single package. The small size of 3.95 mm (L)×3.4 mm (W)×0.9562 mm (H), allows it to be even used in a wide range of miniature commercial application where size and space is a primary concern. The AEDR-850X encoder offers two-channel quadrature digital outputs and a third channel, index digital outputs. Being TTL compatible, the outputs of the AEDR-850X encoder can be interfaced directly with most of the signal processing circuitries. Hence the encoder provides great design in flexibility and easy integration into existing systems.
