DESCRIPTION
The Avtron Model M585 SHAFTach™ Pulse Generator is a
zero-speed incremental rotary transducer. When mounted
to a machine shaft, it provides a specific number of electri-
cal pulses per revolution that are proportional to the shaft's
rotation. The photoelectric sensing system and electronics
are protected by an O-ring sealed, cast aluminum housing.
The M585 design eliminates the need for shaft couplings,
adapter flanges, or accessory mounting faces. The unit
employs a keyless shaft mount to lock the M585's rotor to
a 1.125" diameter shaft. The hub is designed to maintain
concentricity of the rotor and shaft, providing an accurate
output signal. An anti-rotation arm prevents rotation while
allowing for shaft end float.
The available options for the M585, and how they are indi-
cated in the M585 part number, are shown below:

INSTALLATION CONSIDERATIONS
In a conventional pulse generator installation, a flexible cou-
pling is used to compensate for small shaft misalignment
and runout of the driving shaft. Often this misalignment
and runout reduce the life of the mechanical parts and may
cause unwanted modulation of the electrical output signal.
While misalignment is not a problem with the SHAFTach™,
circular runout of the driving shaft may cause a once per
revolution frequency modulation of the output signal. De-
pending upon the application, this may or may not be ac-
ceptable. Typically, a runout of 0.001 TIR or less will not
have an adverse effect.

UNPACKING INSTRUCTIONS
The M585 is supplied with four main items: the pulse
generator with integral specific option package, the
anti-rotation arm, the mounting board with attaching hard-
ware, and the V-ring seal. Check and verify all components
received as ordered. Check for external damage or missing
items. This must be handled by the customer through the
shipper.
Check nameplate against your requirement to make sure
proper style, output, PPR, options, and voltage have been
received.
