3-channel differential or TTL compatible – Wide operating temperature range of -40°C to 115°C High encoding resolution
The Broadcom【AEDR-9920】 is a 3-channel reflective optical encoder. The available options and programmable features include 3-channel digital differential A, B, and I outputs. The AEDR-9920 digital encoder mode provides 2-channel (AB) quadrature digital output and a third channel digital index output. Being TTL compatible, the output of the AEDR-9920 encoder can connect to most signal processing circuits, allowing for easy integration into existing systems and flexible design. The AEDR-9920 encoder is designed to operate in a temperature range of -40°C to 115°C, making it suitable for commercial, industrial, and automotive applications. The encoder houses an LED light source and optical detection circuit in a single package. Its compact size of 4.00 mm (length) × 4.00 mm (width) × 1.05 mm (height) makes it suitable for a wide range of small commercial applications where size and space are primary concerns.
