safety standards, refer to your OMRON website.
Features
A Sensor with Stainless Steel Housing That's Strong, Compact, and Easy to Use!
Resists Oils and Coolants
Industry Top
The E3ZM-C features a simple shape
and structure, and yet provides IP67
protection and oil resistance (oil
resistant to OMRON in-house
standard). This performance exceeds
any previous models from OMRON.
The protective structure eliminates the
need for screws to hold a cover, so
there are no worries about loose
screws leading to liquid penetration.
The compact, easy-to-use E3ZM-C
with built-in amplifier is ideal for oily
environments.
Insulation resistance (MΩ)
Comparison Example for Oil Resistance (Test Oil: Gryton 1700D)
And the model number is laser-marked
on the housing so it's always readable
when the time comes to order
maintenance parts.

Br ight Orange Spot
The [email protected] uses a bright orange LED to generate
a spot that's visible 1 m away. And the sensing distance of
20 m provides more leeway in detection (response time:
2 ms). It all adds up to a more visible, more dependable
worksite.
World's Smallest, and Yet Robust
1m
Patent Pending
The E3ZM-C is the same compact size as the E3Z, making
it the smallest square metal photoelectric sensor in the
world (according to OMRON investigation).
The SUS316L housing makes it robust, and removes all
worries of the coating coming off.
Simple, Yet Dependable M12 Twist-andClick Pre-wired Connectors
These Connectors match the XS5 Connectors released
from August 2006, which reduce wiring work.
They eliminate the troublesome need to control torque
when tightening connectors, and remove worries about
screws loosening due to vibration.

*2. IP69K Degree of Protection Specification
IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050, Part 9.
The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate of 14
to 16 liters/min. The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds
each at 0°, 30°, 60° and 90°while rotating the test piece on a horizontal plane.

*Models numbers for Through-beam Sensors (E3ZM-CT@@(-M1TJ)) are for sets that include both the Emitter and Receiver.
The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3ZM-CT61-L 2M), the model number of the Receiver, by adding "-D"(example:
E3ZM-CT61-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

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.
High-temperature environments may result in
burn injury.
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. 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 0.39 to 0.49 N·m
for M12 metal connectors and 0.3 to 0.4 N·m for M8 metal
connectors.
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.
Rotation Torque for Sensitivity Adjustment and Selector
Switch
Adjust with a torque of 0.06 N·m or less.
Environments with Cleaners and Disinfectants (e.g.,
Food Processing Lines)
Do not use the Sensor in environments subject to cleaners
and disinfectants. They may 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.
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.
11
E3ZM-C
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 (sold
separately) or on a flat surface.
(7) Be sure to turn OFF the power supply before inserting or
removing the connector.
When disposing of the Sensor, treat it as industrial waste.

Oil Resistance
The Sensor has passed oil resistance testing for the oils listed
in the following table. Use this table as a guide when
considering lubricants and cutting oils.

Power Supply
If a commercial switching regulator is used, ground the FG
(frame ground) terminal.
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.
Kinetic
viscosity at
40°C (mm2/s)
Lubricants
Cleaning
Never use thinner or other solvents. Otherwise, the Sensor
surface may be dissolved.
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.
