Unaffected by color or material,
2 m (6.562 ft) distance adjustable range reflective sensing
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.
The EQ-30 series can detect an object 2 m 6.562 ft away.
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.
It features a mechanical 2-turn distance adjuster with an indicator that shows the set distance at a glance.
The sensors features an IP67 rating to allow their use in process lines where water is used or splashed.
Note: If water splashes on the sensor during sensing operation, it may sense water as an object.
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.
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, which can be easily disconnected for replacement is available. In case a problem occurs, anyone can replace the sensor in a minute.
