AEDR-850x Series

(3 Channel Reflective Incremental Encoders)

Description

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° C to 85° C temperature range and hence suitable for both commercial and even industrial end applications.

The encoder houses an LED light source and a photo-detecting circuitry 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 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 3rd 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.
