AEAT-84AD-LBSF0 [Avago]

The AEAT-84AD is an optical absolute multi-turn encoder module with max. Ø55 mm and typical height 12.2 mm. It features 12-bit or 14-bit revolution count versions without requiring batteries or capacitors for revolution counting during power failure. The unit includes an IR-LED circuit board, phototransistor circuit board, and 6-7 gear wheels between PCBs. It supports mechanical coupling via 14-tooth gear pinion (module 0.3), operates at speeds up to 12,000 rpm, and provides immediate position detection on power-up. The module uses a 2x4-pole pin strip for power and signals.
