AEAT-86AD
14/12 Bit Multi-turn Encoder Module with Built-in Controller
Data Sheet
Description
Features
The AEAT-86AD provides all functions as an optoelec-
tronic mechanical unit in order to implement, with single
turn absolute encoder, an absolute multi-turn encoder
with a combined capacity of up to 30 bits at extended
temperature.
The unit consists of an LED circuit board, a phototransis-
tor (PT) circuit board, and gear train arranged in between
the PCBs.
The built-in controller combined positional information
from single turn absolute encoder and multiturn absolute
encoder. It provides control inputs and signal outputs to
application end. The integrated RS-422 differential line
driver output and line receiver are for noise immunity in
transmission line.
Specifications
The multi-turn unit is available in the following versions:
• 12-bit solid shaft with Binary output code
• 14-bit solid shaft with Binary output code
• 12-bit solid shaft with Gray output code
• 14-bit solid shaft with Gray output code
• 16384 (14bits) and 4096 (12bits) revolution count ver-
sions
• Optical, absolute multi-turn assembly with max. Ø55
mm and typical height 13.3 mm.
• Operating temperatures of -40°C to +125°C
• Mechanical coupling by means of gear wheels with
module of 0.3
• Operating speeds up to 12,000 rpm
• A 2x4-pole pin strip for power supply and signal
• Integrated RS422 line driver and receiver
Applications
• Major component of Multi-turn housed encoder
• Cost effective solution for direct integration into OEM
systems
• Revolution detection
Benefits
• No battery or capacitor required for number of revo-
lution counting during power failure
• Immediate position detection on power up
