SERIES HS35R
Heavy Duty Hollowshaft Encoder
Document No.: 702761-0001
Revision Level: S
Sept. 16, 2013
DESCRIPTION
The Series HS35R Sealed Hollowshaft encoder is equipped with an
unbreakable disk that handles the most severe shock and vibration. Its
hollow shaft mount and anti-rotation tether reduce bearing wear and
maintenance. Series HS35R has electrical protection from overvolt-
age, reverse voltage, and output short circuits when ordered with
standard operating temperature configuration.
Series HS35R is not only electrically & thermally isolated (for shaft
sizes 1.125" and under) but also environmentally sealed with shaft
seals at both ends.

IMPORTANT INSTALLATION INFORMATION
Mounting the Encoder: Before Installation, ensure power is discon-
nected from encoder and motor or machine.
CAUTION: The loads applied to the encoder shaft must be in
accordance with the specificatios of this device.
Important Wiring Instructions: Use of shielded cable is recom-
mended for all encoder installations. The shield should be connected
to signal-ground at the receiving device only.
Grounding: For applications with high ground potential differ-
ences, DO NOT ground the encoder through both machine and
controls end. Connect the shield at the controls end only. NOTE:
If the shield is connected at both ends, grounding problems that
degrade system performance can result.
CE Grounding Measures – For best EMC immunity the cable
screen must be grounded on both encoder and controls end. For
cable lengths longer than 30m or outdoor applications, additional
measures must be implemented to comply with CE require-
ments. Connection of the encoder to DC power supply network is
prohibited if CE compliance is required. CE-compliant products
are tested to EN61326-1 EMC.
In all cases, system CE compliance is ultimately the responsibil-
ity of the manufacturer integrating the encoder.
Connecting the shield at both ends can cause grounding
problems that degrade system performance.
If possible, run the encoder cable through a dedicated conduit (not
shared with other wiring). Use of conduit will protect the cable from
physical damage and provide a degree of electrical isolation. Do not
run the cable in close proximity to other conductors that carry current
to heavy loads such as motors, motor starters, contactors, solenoids,
etc. This practice can induce electrical transients in the encoder
cable, potentially interfering with reliable data transmission.
Refer to Electrical Connections table for wiring information.
To avoid possible damage, do not connect or disconnect the encoder
connector or wiring while power is applied to the system.
CAUTION: Unused encoder signal wires must be individually
insulated and under no circumstances be in contact with
ground, voltage sources, or other signal lines.
