AC Function Automatically Compensates Effects of Soiling and Temperature
AC3: Auto Compensation Control for Contamination
(Refer to page 9 for a technical description.)
Patented
Parameters require resetting when static electricity causes dust to adhere to the surface of the Sensor
or Reflector, or when the light emission power drops due to temperature- or time-related changes.
Original OMRON light emission control technology greatly reduces the resetting work involved.

E3ZM-B
Teaching with No Workpiece Required -- Quick and Easy Setting
There is no need for delicate sensitivity adjustments.
Simply adjust the optical axes of the Sensor and Reflector, then press
the Teaching button twice.
This high-reliability design eliminates worries about variations in the
sensitivity settings of different operators.

IP69K Degree of Protection with an SUS316L Housing
The housing is constructed of corrosion-resistant SUS316L,
and the display cover is PES (polyethersulfone) or PEI (polyetherimid).
Both materials are highly resistant to the effects of detergents and
disinfectants.
IP69K degree of protection also allows the E3ZM-B to withstand
washing with high-temperature, high-pressure water.
This makes the E3ZM-B well suited to use in sites requiring a high
level of hygiene.
A Wide Ambient Temperature Range of −40 to 60°C
This wide temperature range meets the needs of the many and diverse
applications in the beverage industry.
Applications
Detecting Plastic Bottles
Precautions for
Correct Use
The E3ZM-B@1/-B@6 are not applicable for detecting transparent objects that exhibit no birefringence, such as
glass bottles.
Transparent objects made of resin also exhibit little birefringence, and cannot be detected with complete stability.
Check the detection stability of objects such as these prior to actual operation.

Technical Descriptions
New Technology for Detecting Transparent Objects Exhibiting Birefringence Patented
P-opaquing (Polarization-opaquing)
Conventional photoelectric sensors for detecting PET bottles
depend on refraction due to the bottle's shape or on the
attenuation of light intensity caused by surface reflection.
However, it is difficult to attain a sufficient level of excess gain
with these methods.
The E3ZM-B utilizes the birefringent (double refraction)
property of PET bottles to dramatically increase the level of
excess gain. The polarization component that is disturbed by
the PET bottles as they pass along the line is cut by a special
and unique OMRON polarization filter. This greatly lowers the
intensity of the light received to provide stable detection with
simple sensitivity adjustment.
“P-opaquing” is a word that was coined to refer to the process
of applying polarization in order to opaque transparent objects
that exhibit the property of birefringence.

Intensity of light received
Conventional photoelectric sensors with built-in amplifiers
are not equipped with functions to compensate for changes
in the intensity of light received caused by dust and other
lens-soiling matter, ambient temperature, and changes that
occur in the LED over time. This makes it comparatively
difficult to achieve long-term, stable detection of objects that
exhibit little change in the intensity of light received, such as
transparent objects.
The AC3 (AC cube) function provided on the E3ZM-B
periodically feeds the intensity of light received during lightON operation back to the light-emitting circuit, to keep the
intensity equal to the value set by teaching.
This allows the E3ZM-B to attain long-term, stable detection
while helping to cut down on maintenance requirements and
improve the equipment operating ratio.

Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for
directly or indirectly ensuring safety of
persons.
Do not use it for such a purpose.
CAUTION
Do not use the product with voltage in excess
of the rated voltage.
Excess voltage may result in malfunction or
fire.
Never use the product with an AC power
supply.
Otherwise, explosion may result.
When cleaning the product, do not apply a
high-pressure spray of water to one part of the
product. Otherwise, parts may become
damaged and the degree of protection may be
degraded.
Precautions for Safe Use
The following precautions must be observed to ensure safe
operation of the Sensor.
Operating Environment
Do not use the Sensor in an environment where explosive or
flammable gas is present.
Connecting Connectors
Be sure to hold the connector cover when inserting or
removing the connector.
When using an XS3F Connector, be sure to tighten the
connector lock by hand; do not use pliers or other tools.
If the tightening is insufficient, the degree of protection will not
be maintained and the Sensor may become loose due to
vibration. The appropriate tightening torque is 0.3 to 0.4 N·m.
When using another, commercially available connector, follow
the usage and tightening torque instructions provided by the
manufacturer.
Load
Do not use a load that exceeds the rated load.
Low-temperature Environments
Do not touch the metal surface with your bare hands when the
temperature is low. Touching the surface may result in a cold
burn.
Oily Environments
Do not use the Sensor in oily environments. They may
damage parts and reduce the degree of protection.
Modifications
Do not attempt to disassemble, repair, or modify the Sensor.
Outdoor Use
Do not use the Sensor in locations subject to direct sunlight.
Cleaning
Do not use thinner, alcohol, or other organic solvents.
Otherwise, the optical properties and degree of protection
may be degraded.
Cleaning
Do not use highly concentrated cleaning agents. Otherwise,
malfunction may result. Also, do not use high-pressure water
with a level of pressure that exceeds the stipulated level.
Otherwise, the degree of protection may be reduced.
Surface Temperature
Burn injury may occur. The Sensor surface temperature rises
depending on application conditions, such as the ambient
temperature and the power supply voltage. Use caution when
operating or performing maintenance on the Sensor.
Cable Bending
Do not bend the cable in temperatures of −25°C or below.
Otherwise, the cable may be damaged.
10
E3ZM-B
Precautions for Correct Use
Do not use the Sensor in any atmosphere or environment that
exceeds the ratings.
Do not install the Sensor in the following locations.
(1) Locations subject to direct sunlight
(2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas
(4) Locations where the Sensor may receive direct vibration
or shock
Connecting and Mounting
(1) The maximum power supply voltage is 30 VDC. Before
turning the power ON, make sure that the power supply
voltage does not exceed the maximum voltage.
(2) Laying Sensor wiring in the same conduit or duct as highvoltage wires or power lines may result in malfunction or
damage due to induction. As a general rule, wire the
Sensor in a separate conduit or use shielded cable.
(3) Use an extension cable with a minimum thickness of
0.3 mm2 and less than 100 m long.
(4) Do not pull on the cable with excessive force.
(5) Pounding the Photoelectric Sensor with a hammer or other
tool during mounting will impair water resistance. Also, use
M3 screws.
(6) Mount the Sensor either using the bracket (order
separately) or on a flat surface.
(7) Be sure to turn OFF the power supply before inserting or
removing the connector.
Power Supply
If a commercial switching regulator is used, ground the FG
(frame ground) terminal.
Power Supply Reset Time
The Sensor will be able to detect objects 100 ms after the
power supply is tuned ON. Start using the Sensor 100 ms or
more after turning ON the power supply. If the load and the
Sensor are connected to separate power supplies, be sure to
turn ON the Sensor first.
Turning OFF the Power Supply
Output pulses may be generated even when the power supply
is OFF. Therefore, it is recommended to first turn OFF the
power supply for the load or the load line.
Load Short-circuit Protection
This Sensor is equipped with load short-circuit protection, but
be sure to not short circuit the load. Be sure to not use an
output current flow that exceeds the rated current. If a load
short circuit occurs, the output will turn OFF, so check the
wiring before turning ON the power supply again. The shortcircuit protection circuit will be reset. The load short-circuit
protection will operate when the current flow reaches 1.8
times the rated load current. When using a capacitive load,
use an inrush current of 1.8 times the rated load current or
lower.
Water Resistance
Do not use the Sensor in water, rainfall, or outdoors.
When disposing of the Sensor, treat it as industrial waste.
