SERIES

Amplifier Built-in

Conforming to

EMC Directive

Not affected by object color or background

Long sensing range 2 m 6.562 ft

As the EQ-30 series is incorporated

with a 2-segment photodiode as the

receiving element with a unique

circuitry, it detects an object at the

same distance regardless of its color

or the background beyond the ad-

justed sensing range.

However, when the background is specular, it may

be necessary to change the angle of the sensor.

EQ-34:

Correlation between material (200200 mm

7.874

7.874 in) and sensing range (typical)

The EQ-30 series can detect an object

2 m 6.562 ft away.

It is suitable for various applications,

such as, sensing objects or positioning

objects traveling on a wide assembly

line, etc.

Insusceptible to contamination on lens

The fixed-focus sensing keeps the

detectability better than diffuse

reflective type sensors even if the lens

is contaminated by dirt, dust, mist, or

smoke under an unclean environment.

Two distances (far and near) can be set

Compact

With EQ-34W, two sensing distances,

Far (Main) and Near (Sub), can be set.

Hence, one sensor can suffice where,

earlier, two were required.

It saves space, since a miniaturized

housing of W20

 H68 D40 mm

W0.787

 H2.677 D1.575 in has

been designed for the fixed-focus

sensing sensor even though the

adjustable sensing range is 2 m 6.562 ft

long.

EQ-30 PRECAUTIONS FOR PROPER USE Distance adjustment Notes: 1) Turn the distance adjuster gradually and lightly with the attached screwdriver. If the distance adjuster is over turned or pressed heavily, it may be damaged. Notes: 2) The Far (Main) distance adjustment should be done before the Near (Sub) distance adjustment. Take care that the Near (Sub) setting distance changes with change in the Far (Main) setting distance. EQ-34W - .
