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.

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 M

Ω min.
