Ordering Information

Sensors

* The Dark-ON/Light-ON (selectable) models are normally used as dark-ON models. To use them as light-ON models, short-circuit the L terminal and positive (+)

terminal.

An EE-1001-1 Connector with the terminals already short-circuited is also available.

Accessories (Order Separately)

Note: For details, refer to the Photomicro Sensors Accessories on EE-@ which can be accessed from your OMRON website.

* EE-1009- or EE-1010-series Connectors have a builtin locking mechanism to prevent cable disconnection when only the cable is pulled. To remove the Connector

from the Sensor, grip the top and bottom of the Connector firmly and push into the Sensor once before pulling out. The locking mechanism prevents the Connector

from being removed by pulling on the cable only and enables removal only when the Connector (housing) is pulled.

Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

Make sure that this product is used within the rated ambient

environment conditions.

● Wiring

Soldering

•When direct soldering to the terminal, use the following guidelines.

Soldering Conditions

•The terminal base uses a polycarbonate resin, which could be

deformed by excessive soldering heat, resulting in damage to the

product’s functionality.

Cable Extension

•When extending the cable, use an extension cable with conductors

having a total cross-section area of 0.3 mm2. The total cable length

must be less than 10 m.

● Installation

The photomicrosensor is built into the device being used and so is not

equipped to deal with interference from an external light source.

When using the sensor in an area exposed to an incandescent lamp,

install so as to minimize the effects of external light sources.

● Sensitivity Adjustment

Use the special screwdriver (sold together) for sensitivity

adjustment.

•When an excessive force is applied to sensitivity adjuster, it may be

damaged.

•The shaft of the sensitivity adjuster is charged. Connect a DC

power supply incorporating an insulated transformer to the

photomicrosensor. Do not connect a DC power supply

incorporating an autotransformer or the user may receive an

electric shock when adjusting the sensitivity.

Adjustment

Procedure

1.Set the sensitivity of the

photomicrosensor to

minimum, place the sensing

object in the sensing

position, turn the sensitivity

adjuster clockwise slowly

until the light indicator is lit

(point A).

2.Remove the sensing object,

at which time the light

indicator will be OFF.

Further turn the sensitivity

adjuster clockwise slowly

until the light indicator is lit

again (point B). The

operation indicator will not

light again if the background

object does not reflect light,

in which case refer to

‘Sensitivity Adjustment with

No Background Object”.

3.Set the sensitivity adjuster

at the center (point C)

between point A and B.

Points A and B will be very

close if the sensor is

influenced by excessive

light reflected by the

background object, in which

case take the following

preventive measures.

(1)Separate the sensor and

the background object

by a distance of 20 mm

min.

(2) Cover the surface of the

background object with

a material with a small

reflection factor, such as

black sponge.

4.After setting the sensitivity

adjuster to point C, check if

the light indicator is lit on

placing the sensing object at

the sensing position and not

lit on removing the sensing

object.
