AEAT-84AD
14/12 Bit Multi-turn Encoder Module
Data Sheet
Description
The AEAT-84AD provides all functions as an optoelec-
tronic-mechanical unit in order to implement, with single
turn absolute encoder, an absolute multiturn encoder
with a combined capacity of up to 30 bits at extended
temperature.
The unit consists of an IR-LED circuit board, a phototrans-
istor (PT) circuit board, and 6 or 7 gear wheels arranged in
between the PCBs.
Specifications
The multi-turn unit is available in the following versions:
 12-bit solid shaft
 14-bit solid shaft
Features
 16384 (14bits) and 4096 (12bits) revolution count
versions
 Optical, absolute multi-turn assembly with max. Ø 55
mm and typical height 12.2 mm.
 Operating temperatures of -40° C to +125° C
 Mechanical coupling by means of 14 teeth gear pinion
with module of 0.3
