Broadcom AEDR-9930EL Three-Channel Reflective Incremental Linear Encoder
The Broadcom AEDR-9930EL is a versatile three-channel reflective optical encoder offering selectable and programmable digital differential outputs (A, B, and I). It provides two-channel (AB) quadrature digital outputs for direction sensing and a third channel digital index output. With TTL compatibility, it integrates seamlessly into most signal processing circuitries. Designed for a wide operating temperature range of 40C to +115C, it is suitable for commercial, industrial, and automotive applications. Its compact 5.00 mm (L) 5.00 mm (W) 1.05 mm (H) surface-mount leadless package makes it ideal for miniature applications where space is a constraint. The encoder features a built-in LED light source and photo-detecting circuitry.
