The Broadcom® AEDR-871x encoder is the smallest 3-channel optical encoder with digital outputs that employs Reflective Technology for motion control.The encoder is designed to operate over the –40°C to 85°C temperature range and so is suitable for both commercial and industrial applications.AEDR-871x offers high resolution (318 LPI) with built-in interpolation, enabling great flexibility and versatility in resolution range. The compact dimensions of 3.95 mm (L) × 3.4 mm (W) × 0.9562 mm (H) coupled with the low operating 3.3V option allows it to be used in a wide range of miniature commercial applications and portable devices in which space and power consumption is a primary concern.AEDR-871x encoder offers two-channel (AB) quadrature digital outputs and a third channel, index digital outputs. Being TTL compatible, the outputs of the AEDR-871x encoder can be interfaced directly with most of the signal processing circuitries. Therefore, the encoder provides great design-in flexibility and easy integration into existing systems.
