Avago三通道光学编码器AEDR－850X

The AEDR-850x encoder is the smallest 3 channel optical encoder in the world with digital outputs employing reflective technology for motion control purposes. The encoder is designed to operate over -20° C to 85° C temperature range and therefore is suitable for both commercial and industrial end applications.

This 3 channel optical encoder houses an LED light source and a photodetecting circuit in a single package. The small size of 3.95 mm (L) x 3.4 mm (W) x 0.9562 mm (H), allows it to be used in a wide range of miniature commercial applications where size and space constraints exist.

The AEDR-850x series encoders offer two-channel quadrature digital outputs and a 3rd channel, index digital outputs. Being TTL compatible, the outputs of the AEDR-850X 3 channel optical 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.
