Broadcom AEDR-9930EL 3-Ch Reflective Optical Encoders
Broadcom AEDR-9930EL 3-Channel Reflective Optical Encoder delivers selectable and programmable options of digitally differential A, B, and I outputs. The AEDR-9930EL digital encoder mode offers two-channel (AB) quadrature digital outputs and a third-channel digital index output.
The Broadcom AEDR-9930EL encoder is TTL compatible with interfaced outputs for most signal processing circuitries. Therefore, the AEDR-9930EL enables easy integration and flexible design-in into existing systems.
The device is developed to operate over a -40°C to +115°C temperature range and is ideal for commercial, industrial, and automotive end applications. The encoder encloses an LED light source and photo-detecting circuitry in a 5.00mm × 5.00mm × 1.05mm (LxWxH) single package. The small size of the AEDR-9930EL permits usage in a wide range of miniature commercial applications, where size and space are primary concerns.
