Hardly affected by object color or background

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 adjusted sensing range.
However, when the background is specular, it may be necessary to change the angle of the sensor.

Long sensing range 2 m 6.562 ft

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.

Two distances (far and near) can be set [EQ-34W]

With EQ-34W, two sensing distances, Far (Main) and Near (Sub), can be set. Hence, one sensor can suffice where, earlier, two were required.

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.

Mechanical 2-turn adjuster with indicator

It features a mechanical 2-turn distance adjuster with an indicator that shows the set distance at a glance.

Waterproof

It has IP67 protection. It can be used in places splashed with water.

Compact

It saves space, since a miniaturized housing of W20 x H68 x D40 mm W0.787 x H2.677 x D1.575 in has been designed for the adjustable range reflective sensing sensor even though the adjustable sensing range is 2 m 6.562 ft long.

Principle of adjustable range reflective sensing with 2-segment photodiode

Normal reflective type sensors operate by sensing the variation in the amount of incident beam.
However, the adjustable range reflective sensing type sensor incorporating the 2-segment photodiode operates by sensing the variation in the incident beam angle. Thus, the output is activated according to the distance of the object from the sensor.
This system helps the EQ-30 series in being unaffected by object color or a background, enabling stable sensing.

Sensing is based on the difference in the incident beam angle of the dotted line and the solid line in the above figure.

Plug-in connector type is available

Plug-in connector type, which can be easily disconnected for replacement is available. In case a problem occurs, anyone can replace the sensor in a minute. (Excluding EQ-34W)
