Frequently Asked Questions - E3ZM OMRON

What is the type of OMRON E3ZM sensor?

The E3ZM sensor is a photoelectric proximity sensor available in through-beam, retroreflective, diffuse, and BGS (fixed background suppression) versions.

What is the required power supply for the E3ZM sensor?

The power supply must be between 10 and 30 VDC (with 10% peak-to-peak ripple). Never use AC power.

How to clean the E3ZM sensor?

Use approved detergents and disinfectants (see resistance table). Avoid organic solvents such as thinner or alcohol, and do not use high-pressure water jets exceeding the specifications.

What are the available output modes?

The sensors are available with NPN or PNP output, with Light-ON/Dark-ON selection via a switch or wiring. Maximum load current is 100 mA.

What is the maximum sensing distance?

The distance depends on the model: up to 15 m in through-beam, 4 m in retroreflective (with E39-R1S reflector), 1 m in diffuse, and 10 to 200 mm in BGS.

Is the E3ZM sensor suitable for humid or washdown environments?

Yes, it has protection ratings IP67 and IP69K (high-pressure and high-temperature water resistance). Suitable for frequent washdown areas.

How to install the E3ZM sensor?

Mount the sensor on a flat surface or use mounting brackets (sold separately). Use M3 screws with a maximum tightening torque of 0.5 N·m. Do not strike the sensor during mounting.

What accessories are available for the E3ZM?

Reflectors (E39-R1, R1S, etc.), mounting brackets (E39-L153, L98, etc.), M8/M12 connectors, and protective covers. Reflectors are not supplied with retroreflective models.

Is the E3ZM sensor suitable for detecting transparent objects?

The retroreflective models with M.S.R. function can detect transparent objects such as glass or plastic bottles.

What safety precautions should be observed?

Do not use the sensor for personal safety. Do not exceed 30 VDC, avoid explosive or corrosive environments, and do not use solvents for cleaning. Observe the maximum tightening torque for sensitivity adjustment (0.06 N·m).

Safety Precautions

Refer to Warranty and Limitations of Liability on page 20.

Warning

This product is not designed or rated for ensuring safety of persons. Do not use it for such 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 concentrated spray of water to one location. 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 0.3 to 0.4N· m .

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.

Precautions for Safe Use

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 mm^2 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 shortcircuit protection will operate when the current flow reaches 1.8 times the rated load current. When using an L 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

Use a mounting torque of 0.5 N·m max.

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.

Category	Product name	Concen- tration	Temper- ature	Time
Chemical	Sodium hydroxide (NaOH)	1.5 %	70 °C	240 h
	Potassium hydroxide (KOH)	1.5 %	70 °C	240 h
	Phosphoric acid \( \left( {{\mathrm{H}}_{3}{\mathrm{{PO}}}_{4}}\right) \)	2.5 %	70 °C	240 h
	Sodium hypochlorite (Na- CIO)	0.3 %	25 °C	240 h
	Hydrogen peroxide \( \left( {{\mathrm{H}}_{2}{\mathrm{O}}_{2}}\right) \)	6.5 %	25 °C	240 h
Alkaline foam detergent	P3-topax-66s (Manufactured by Ecolab)	3.0 %	70 °C	240 h
Acidic foam detergent	P3-topax-56 (Manufactured by Ecolab)	5.0 %	70 °C	240 h
Disinfectant	P3-oxonia active 90 (Manufactured by Ecolab)	1.0 %	25 °C	240 h
	TEK121 (Manufactured by ABC Compounding)	1.1 %	25 °C	240 h

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 100M min.
