Nidec-Avtron Makes the Most Reliable Encoders in the World
When mounted to a machine shaft, the HS45 design eliminates the
need for shaft couplings, adapter flanges, or accessory mounting
faces. The high clamping-force collar holds the HS45 in place, even
under severe vibration & shock. A high-performance composite shaft
insert provides electrical isolation from motor shaft currents. The shaft
insert permits models to fit a range of shaft sizes from 5/8" to 1 1/8"
[16mm - 30mm]; additional sizes available upon request. An anti-
rotation arm prevents housing rotation while allowing for shaft end
float.
The HS45 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 HS45
electronics are potted, providing full protection against liquids.
The outputs are protected against short circuits and wiring errors.
DESCRIPTION
The Avtron Model HS45 is a heavy duty incremental encoder (also
known as tachometer or rotary pulse generator). Its output is directly
proportional to shaft position (pulse count) or speed (pulse rate). The
HS45 operates down to zero speed and can be used for both control
and instrumentation applications.
CAUTION
Do not utilize HS45 in hazardous locations which
require ATEX, UL, CUL, CSA, or other explosion protection
certification. HS45 is not certified for hazardous
locations. Use XR models for hazardous applications.

HS45 2
Each HS45 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 HS45 has a diagnostic package that includes Adaptive Electronics
and a Fault-Check output and red/green LED for local indication.
With this package, the HS45 can maintain itself, and provide an
alarm if there is a problem before the problem causes unscheduled
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 HS45 by constantly
monitoring and correcting duty cycle and edge separation over time.
FAULT-CHECK
If the Adaptive Electronics reach their adjustment limit, the LED will
turn red and Fault-Check alarm will notify the drive and operator of
an impending failure. This output can occur before a failure, allowing
steps to be taken to replace the unit before it causes unscheduled
downtime. Fault-Check annunciation is available as an “alarm” output
through the connector.
SAFETY
The HS45 is not considered as a safety device and is not suitable for
connection into a safety system. The mechanical overspeed switch
(option 6xx) is suitable for connection into safety systems.
CAUTION
Do not disassemble mechanical overspeed option.
Doing so may modify the overspeed set point or cause
the switch to malfunction. If the factory seals are not
intact on the overspeed switch, do not use it--return to
the factory for service and calibration.

HS45 6
CAUTION
Be careful not to damage clamping fingers of hollow
shaft during handling. Do not tighten clamping collar
before installation onto motor shaft.
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.
Equipment needed for installation
Supplied:
HS45 Encoder
Shaft Sizing Insert for all clamp style models
For 16mm center-bolt style ONLY: centering (tapered) ring
Optional:
Anti-Rotation Arm Kit
Thread Locker (blue)
Not Supplied:
Open Wrenches
“G”, “P”, “T”, ”U”-Tether: 9mm, 10mm
“D”, “E”,”F”,”H”,”M”,”U”-Tether: 7/16”,1/2”, 9/16”, 3/4”
M5" T-handle hex wrenches or torque wrench with M5 bits
(Torque wrench required for Center Bolt Mounting Style).
Dial Indicator Gauge
Caliper Gauge
The hollow shaft HS45 design eliminates the potential for coupling
failures from misalignment, however, excessive housing movement
(wobble) may cause undesirable vibrations and bearing damage. The
higher the RPM, the more severe the vibration will be from housing
movement. In a typical installation a housing movement of 0.007"
[0.18mm] TIR or less (as measured at the outside diameter of the
main encoder body) will not have an adverse effect. For overspeed
applications, TIR should be < 0.002” [0.05mm].
1) Disconnect power from equipment and encoder cable.
2) Use caliper gauge to verify motor shaft is proper diameter and
within allowable tolerances: +0.000", -0.0005" [+0.00, -0.013mm].
3) Clean machine shaft of any dirt and remove any burrs.
4) Use dial indicator gauge to verify the motor shaft: Total Indicated
Runout (TIR) <0.002" [0.05mm].
5) Install the anti-rotation bracket tether to the face of the encoder
using M6 Hex screws and lock washers, included with the tether.
Tighten to 65 in-lbs [7.5n-m]
5a) (optional) For non-through-shaft (end of shaft) applications, the
optional rear cover may be installed for optimum performance
against dirt, liquid sprays and impacts.
For Clamp Collar Mounting Style:
6) Loosen clamping collar screws.
NOTE
These screws have factory applied thread locker, no
further thread locker application is required.
7) Test Fitting: carefully slide the encoder onto the shaft to verify
fit. Ensure a minimum of 1/8" [2mm] between encoder and
mounting surface. DO NOT FORCE. Encoder should slide on
easily. If the encoder does not fit easily, remove it, verify shaft
size, and check for burrs and shaft damage.
8a) For end of shaft applications using the clamping collar system,
place the HS45 at least 2” onto the shaft. (For larger bore shafts
1” [25mm] or larger, minimum shaft engagement is 1.75”
[45mm]; for overspeed applications the minimum engagement is
2.65” [67mm]) Ensure the stub shaft does not contact the rear
cover.
8b) For thru-shaft applications using the clamping collar system,
remove the rear shaft cover (screws are retained by the cover)
and position the HS45 as required. Thru-shaft installation is not
available in overspeed applications.
9) Tighten screws on clamping collar evenly until snug, then tighten
each screw as follows:
For bore sizes up to 1” [25mm] 38 in-lb [4.3 Nm]
For bore sizes >1” [25mm] 66 in-lb [7.5 Nm]
DO NOT USE A STANDARD RIGHT ANGLE WRENCH. Use only a
T-handle hex wrench or torque wrench with hex bit.
Or For End of Shaft Center Bolt Mount Style:
6) Remove the rear cover from the HS45.
7a) For 17mm taper shaft mount: Carefully slide the encoder onto
the shaft to verify fit. DO NOT FORCE. Encoder should slide on
easily. If the encoder does not fit easily, remove it, verify shaft
size, and check for burrs and shaft damage.
7b) For 16mm center bolt shaft mount: Slide the centering ring over
the motor shaft. Carefully slide the encoder onto the shaft to
verify fit. DO NOT FORCE. Encoder should slide on easily. If the
encoder does not fit easily, remove it, verify shaft size, and check
for burrs and shaft damage.
8) Insert center mounting screw (M6 provided) through the body of
the encoder into the stub shaft tapped hole and tighten to 66 in-
lbs [7.5n-m]
9a) Replace rear cover onto the HS45. Use a wrench on the external
flats if necessary. Tighten the cover screws.
10a) For threaded rod tethers, adjust to proper length by selecting
combinations of short and long piece as required and thread
together for final length adjustment. Attach free end of the anti-
rotation arm to the bracket tether using the shoulder bolt
provided.
11) Secure free end of the anti-rotation bracket to frame using bolt or
T-bolt provided. The bracket should be parallel to the encoder
face, 90 degrees to the shaft to avoid encoder bearing damage.
Use additional washers as needed to ensure the tether is parallel
to the encoder face.
12) An M8 threaded hole is provided in the encoder shaft to permit a
M8 jack bolt for removal
MODIFICATION
The HS45 can be modified in the field to easily adapt to new
applications.
TO CHANGE ELECTRICAL CONNECTOR STYLE:
1) Remove electrical power and disconnect the mating plug.
2) Unscrew the (4) M5 screws (4mm hex).
3) Pull the connector header away from the encoder gently.
4) Disconnect the ribbon connector to the encoder body.
5) Connect the ribbon connector to the new connector header

HS45 7
6) Attach the new connector header to the encoder using the (4) M5
screws. Tighten to 30 in-lbs [3.4n-m]. Be sure the ribbon
connector fits in the open pocket under the header and is not
crushed or pinched by the connector header.
TO CHANGE BORE SIZE INSERT:
1) Remove electrical power.
2) Remove the encoder from any existing mounting.
3) Remove the rear encoder cover (if present) (4 screws are retained)
4) Remove the retaining snap-ring around the insert.
5) Remove the insert from the encoder bore. The insert should slide
out easily. DO NOT hammer on the insert to remove it.
6) Slide new insert inside encoder shaft.
7) Reinstall the retaining snap ring over the insert.
8) Reinstall the rear encoder cover as required.
WIRING
CAUTION
Be sure to remove power before wiring the encoder.
Be sure to ground the cable shield: At the drive end. See
note below for Danaher/Northstar wiring.
Refer to the wiring diagrams for specific information on each option.
The AV45 can be wired for single phase or two phase, either with
or without complements, with or without markers. For bidirectional
operation, Phase A channel leads phase B channel for clockwise shaft
rotation as viewed from the anti-drive or accessory end of the motor
(AV45 mounting end).
CAUTION
Be sure to observe maximum current limits for
mechanical overspeed switch option. Exceeding these
limits can cause arcing and cause switch failure; this
may result in property damage, injury or even death.
NOTE
Wiring option “G” provides a pinout compatible with
NorthstarTM encoders, with a cable shield connection
on pin 10. Note that this option does not ground the
shield; Avtron still recommends grounding the shield at
the drive end of the cable for all wiring options.
CORRECTIVE ACTION FOR PHASE REVERSAL
1) Remove Power.
2) Exchange wires on cable, either at encoder cable end,
or at speed controller end (but not both).
a) Single Ended 2 Phase Wiring (see wiring diagram)
Exchange A and B at the use end of the wires.
b) Differential 2 Phase Wiring (see wiring diagram)
Exchange either A with A– in the phase A pair OR
B with B– in the phase B pair but NOT both.
3) Apply Power.
4) Verify encoder feedback is correct, using hand rotation
of shaft, or jog mode of the speed controller.
Interconnecting cables specified in the wire selection chart are based
on typical applications. Physical properties of cable such as abrasion,
FIGURE 5
VARIATION > ± 15%
PHASE A
PHASE B
temperature, tensile strength, solvents, etc., are dictated by the
specific application. General electrical requirements are: stranded
copper, 22 through 16 AWG (Industrial EPIC connector type options
can use 14 AWG), each wire pair individually shielded with braid or foil
with drain wire, .05 uf of maximum total mutual or direct capacitance,
outer sheath insulator. See specifications for maximum cable length.
Stranded 22 AWG wire should not be used for cable runs greater then
61 meters. If 22 AWG is used with EPIC type connector options the
wire ends should be tinned.
FAULT-CHECK
After power-up and the rotor position is checked by the sensor, the
Fault-Check LED will turn green.
If the adaptive electronics reach their adjustment limit for any reason,
the Fault-Check alarm and LED will notify the drive and operator of
an impending failure. The LED will turn red if the Adaptive Electronics
reach their adjustment limit. This output occurs before an actual
failure, allowing steps to be taken to replace the unit before it causes
unscheduled downtime. Fault-Check annunciation is available as an
“alarm” output through the connector and as an integral LED.
TROUBLESHOOTING
If the drive indicates a loss of encoder/tach fault and the HS45
fault-check LED is not illuminated, check the encoder power supply.
If power is present, check polarity; one indicator of reversed power
supply is that all outputs will be high at the same time. If the drive
indicates encoder fault, but the LED shows GREEN, then check the
wiring between the drive and the encoder. If the wiring appears
correct and in good shape, test the wiring by replacing the HS45. If the
new unit shows GREEN, and the drive still shows encoder loss/tach
fault, then the wiring is faulty and should be repaired or replaced.
If the alarm output and/or LED indicate a fault (RED) on a properly
mounted HS45 and the rotor is properly located, replace the HS45.
An oscilloscope can also be used to verify proper output of the HS45
encoder at the encoder connector itself and at the drive/controller
cabinet. If the outputs show large variations in the signals at steady
speed (jitter or “accordion effect”, see figure 5 above), replace any
magnetized material nearby with non-magnetic material (aluminum,
stainless) (shafts, etc). If variations persist, consider replacing with
super-shielded models, option -004.
