Reflective Optical Encoder

Currently Viewing:

The AEDR-8300 series is the smallest optical encoder employing reflective technology for motion control purposes. The encoder combines an emitter and a detector in a single surface mount leadless package. When used with a codewheel or linear codestrip, the encoder translates rotary or linear motion into digital output.

The AEDR-8300 series outputs TTL compatible quadrature signals; and as such, can be interfaced directly with most of hte signal processing circuitries. Hence, the encoder provides great design-in flexibility and easy integration into existing systems.

The AEDR-8300 series provides motion sensing at a competitive cost, making it ideal for high volume applications, Its small size and surface mount package make it ideal for printers, copiers, card readers and many consumer products, particularly where space and weight are design constraints.
