AEDR-9930E/AEDR-9930EA中文资料Three-Channel Reflective Incremental Encoder Programmable Interpolator Digital Output (397 LPI)数据手册Broadcom规格书

描述 Description

The Broadcom® AEDR-9930E is a three-channel reflective optical encoder. The selectable and programmable options available are three-channel digital differential A, B, and I output.The AEDR-9930E digital encoder mode offers two-channel (AB) quadrature digital outputs and a third channel digital index output. Being TTL compatible, the outputs of the AEDR-9930E encoder can be interfaced with most of the signal processing circuitry. Therefore, the encoder provides easy integration and flexible design-in into existing systems.The AEDR-9930E encoder is designed to operate over –40°C to 115°C temperature range and is suitable for commercial, industrial, and AEDR-9930EA –40°C to 125°C automotive end applications.The encoder houses an LED light source and a photodetecting circuitry in a single package. The small size of 5.00 mm (L) × 5.00 mm (W) × 1.05 mm (H) allows it to be used in a wide range of miniature commercial applications, where size and space are primary concerns.
