with High-speed Response (50 µs) and Accuracy in Spite of
Sensing Object Movement

Color Mark Sensors Now Join the E3ZM Series of
Photoelectric Sensors for the Food Industry
■Coaxial Optical System in a Compact Design
Although the E3ZM-V is only 11 × 21 ×
32 mm, it uses a coaxial optical system.
Even if the sensing object is inclined,
reflected light is captured with the
coaxial optical system to provide stable
detection.

■IP69K Degree of Protection with an SUS316L Housing
The housing is constructed of corrosion-resistant
SUS316L, and the display cover is PES
(polyethersulfone). Both materials are highly
resistant to the effects of detergents and
disinfectants. IP69K degree of protection also
allows the E3ZM-V to withstand washing with
high-temperature, high-pressure water. This
makes the E3ZM-V well suited to use in sites
requiring a high level of hygiene.
■Space-saving Design with an SUS316L Housing
The compact design reduces volume by 90%
compared with previous OMRON models.
And the world-standard dimensions
contribute to standardized installation
specifications. Previous OMRON model
(E3M-V)
Only 10%
the volume!

Precautions for Safe Use

E3ZM-V
10
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 high-
voltage 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 mm2and less than 50 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 (sold 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 short-
circuit protection circuit will be reset. The load shortcircuit
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.
Mounting Diagram
Resistance to Detergents, Disinfectants, and Chemicals
•The Sensor will maintain sufficient performance in typical
detergents and disinfectants, but performance may suffer in
some types of detergents, disinfectants, and chemicals.
Refer to the following table prior to use.
•The E3ZM has passed detergent and disinfectant
resistance testing for the substances listed in the following
table. Use this table as a guide when considering
detergents and disinfectants.
Note: The Sensor was immersed in the above chemicals, detergents, and
disinfectants for 240 h at the temperatures given, and then passed an
insulation resistance test at 100 MΩmin.
Restrictions on Sensing Objects
Do not use this Sensor if the color and pattern of the
background are similar to those of the mark.
Detection of Glossy Objects

Automatic teaching (Remote)
1. Send a pulse with a duration of at least 2 s but less than 10 s min. to the remote control input (pink).
2. Teaching will be performed automatically when the mark (the light level with the shorter detection time) passes
through the beam spot.
•Make sure the mark passes through the beam spot for at least 1.5 ms.
•Pass the mark through the beam spot at least seven times to complete the teaching process.
•There must be a difference in light intensity between the mark and the background for teaching to be successful.
3. Detection will begin and the output will turn ON when the mark (the light level with the shorter detection time) is
detected.
Note: Determine when teaching has been completed by confirming that the output turns ON for the mark and OFF for the background. If the output does not turn ON
for the mark and OFF for the background within one minute after the remote control input is applied, teaching has not been successful. Apply the remote control
input again.
Precautions for Using Automatic Teaching (Remote)
•With automatic teaching (remote), the output is always turned ON for the light level with the shorter detection time. Use 2-point
teaching (manual) to turn OFF the output for the light level with the shorter detection time.
•Faulty detection is possible when using automatic teaching (remote) if there is considerable movement in the sensing object or
if the surface of the object is stepped or contains protrusions.
In cases such as these, use 2-point teaching.
•Do not use automatic teaching for backgrounds that are not monochrome.
