MODEL
AV6A
ABSOLUTE OPTICAL
SOLID SHAFT ENCODER
DESCRIPTION
The Avtron Model AV6A is a light mill duty absolute encoder. It
expresses the position of rotation as an output message or value.
AV6A can measure a single turn of rotation or multiple rotations. The
AV6A measures the shaft rotation and position without the need for
external power or internal batteries or capacitors through its multi-
turn gear system. The AV6A operates down to zero speed and can be
used for both control and instrumentation applications.
CAUTION
Do not utilize AV6A in hazardous locations which
require ATEX, UL, CUL, CSA, or other explosion protection
certification. AV6A is not certified for hazardous
locations.
The AV6A is designed for mounting on flanges (58mm, 36mm,
1.25”), or on a foot mount bracket for coupling. The AV6A is not
recommended for pulley or chain drive applications.
SAFETY
The AV6A is not considered as a safety device and is not suitable for
connection into a safety system.
WARNING
Installation should be performed only by qualified
personnel. Safety precautions must be taken to ensure
machinery cannot rotate and all sources of power are
removed during installation.
INSTALLATION
Refer to the back page of these instructions for outline and mounting
dimensions.
