for Greater Hygiene
We used SUS316L for the case and
the best material for all parts to
achieve 200 times the durability of
the E3Z (in 1.5% solution of sodium
hydroxide at 70˚C) to make the
E3ZM suitable for the cleaning
conditions of food-processing
machinery.
The first IP69K* (DIN 40050-9)
protective structure in the world
for a square metal photoelectric
sensor. Suitable for high-
temperature, high-pressure jet
water spray cleaning applications.

Few indentations in the shape
means less dust and water can
collect, making the E3ZM more
hygienic. No labels have been used
in order to prevent foreign matter
contaminating food products. The
E3ZM model and lot numbers are
imprinted using a laser marker.

Structural Design That Provides Excellent Environment-resistance*
Unique Members of the E3ZM Family
BGS Reflective Models
E3ZM-LS6@H/-LS8@H
Three models with different fixed sensitivity (rated sensing distances)
have been created. These models cover the sensing ranges of the E3Z-
LS61.
Through-beam Inner Aperture Models
E3ZM-T63
Fine beam without attaching an external aperture. This eliminates
malfunctions from residual water drops, even immediately after
washing.
A Better Fit for the Application
The E3ZM can be used in those harsh cleaning
environments in which the E3Z was difficult to use.
E3ZM passed the material resistance tests and is certified
by Ecolab.
Waterproofing ring: Fluorine rubber
Excellent resistance to detergents and
disinfectants.
Optical plate:
Polymethylmethacrylate (PMMA)
Excellent resistance to detergents
and disinfectants. High
transparency and other qualities
give PMMA excellent optical
characteristics.
Seal
The seal provides the durability to
high-temperature and high-pressure
water that complies with IP69K.
*Do not use the E3ZM in an oily environment.
Indicator cover: Polyethersulfone (PES)
Excellent resistance to detergents and disinfectants.
Excellent resistance to detergents and
disinfectants. Also has excellent abrasion
resistance.

Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons. Do not use it for such a purpose.
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
concentrated 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.
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.
If the XS3F is used, always tighten the connector cover by hand. Do
not use pliers.
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.
If other commercially available connectors are used, follow the
recommended connector application conditions and recommended
tightening torque specifications.
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.
Oily Environments
Do not use the Sensor in oily environments.
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.
Washing
Do not use highly concentrated detergents. They may cause
malfunction. Do not use high-pressure water spray in excess of the
specifications.
Surface Temperature
Burn injury may occur. The Sensor surface temperature rises
depending on application conditions, such as the surrounding
temperature and the power supply voltage. Use caution when
operating or washing the Sensor.
WARNING
CAUTION
Precautions for Safe Use
E3ZM
14
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 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.
Cleaning
Never use thinner or other solvents. Otherwise, the Sensor surface
may be dissolved.
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 short-
circuit protection will operate when the current flow reaches 1.8 times
the rated load current. When using a C load, use an inrush current of
1.8 times the rated load current or higher.
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
Performance is assured for typical detergents and disinfectants, but
performance may not be maintained for some detergents and
disinfectants. Refer to the following table when using these agents.
The E3ZM passed testing for resistance to detergents and
disinfectants performed using the items in the following table. Refer
to this table when considering use of detergents and disinfectants.
Note: The Sensor was immersed in the chemicals, detergents, and
disinfectants listed above at the temperatures in the table for 240 hours
and then passed an insulation resistance of 100 MΩ min.
