Broadcom AEDR-8502-102, Encoder 3, 8-Pin SMD

The Broadcom 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.
