MODEL
AV6A
SOLID SHAFT
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.

DESCRIPTION
The Avtron Model XR4F, SMARTSafe™ is a
heavy duty
incremental
encoder for hazardous atmosphere applications (also known
as tachometer or rotary pulse generator). Its output is directly
proportional to shaft position (pulse count) or speed (pulse rate). The
XR4F operates down to zero speed and can be used for both control
and instrumentation applications.
CAUTION
The XR4F is designed for use in hazardous applications
which require protection from gas or dust ignition for
safe operation. Proper selection, wiring and installation
procedures are essential to ensuring safe conditions.
The XR4F is designed for mounting on European B10 style flanges
(85mm flange, 100mm bolt circle), or on a foot mount bracket for
coupling. The XR4F is not recommended for pulley or chain drive
applications.
The XR4F utilizes magnetoresistive sensors. This proven technology
is ideal for rugged environments since it is immune to many
contaminants that cause optical encoders to fail. All of the XR4F
electronics are potted, providing full protection against liquids.
The outputs are protected against short circuits and wiring errors.
Each XR4F has a two-phase output (A, B) 90° out of phase, with
complements (A–, B–), (A Quad B Output). A marker pulse with
complement (Z, Z–) is also present.
The XR4F has a diagnostic package that includes Adaptive Electronics
and a Fault-Check output and red/green LED for local indication. With
this package, the XR4F can maintain itself, and provide an alarm if
there is a problem before the problem causes un scheduled downtime.
ADAPTIVE ELECTRONICS
A perfect duty cycle consists of a waveform whose “high” and
“low” conditions are of the same duration (50%/50%). It is possible
over time for the duty cycle and edge separation to change due
to component drift, temperature changes, or mechanical wear.
The Adaptive Electronics extend the life of the XR4F by constantly
monitoring and correcting duty cycle and edge separation over time.
INSTALLATION
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.
