Basic Information
Unaffected by color or material,
2 m (6.562 ft) distance adjustable range reflective sensing
CE Approved
Features
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.
EQ-34: Correlation between material (200 x 200 mm 7.874 x 7.874 in) and sensing range (typical)
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.
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
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.
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.

Stability indicator
- Since the EQ-30 series uses a 2-segment photodiode as its receiving element, and sensing is done based on the difference in the incident beam angle of the reflected beam from the sensing object, the output and the operation indicator operate according to the object distance.
Further, the stability indicator shows the margin of the incident light intensity and not that of the object distance.
Hence, the distance at which it lights up/off depends on the object reflectivity and is not at all related to the output operation. Do not use the sensor when the stability indicator is off (unstable light received condition), since the sensing will be unstable.
Others
- Do not use during the initial transient time (50 ms) after the power supply is switched on.
- When connecting the mating cable to the plug-in connector type, the tightening torque should be 0.4 N·m or less.
Mounting
- The tightening torque should be 0.8 N·m or less.
- Care must be taken regarding the sensor mounting direction with respect to the object’s direction of movement.
Do not make the sensor detect an object in this direction because it may cause unstable operation.
- When detecting a specular object (aluminum or copper foil) or an object having a glossy surface or coating, please take care that there are cases when the object may not be detected due to a small change in angle, wrinkles on the object surface, etc.
- When a specular body is present below the sensor, use the sensor by tilting it slightly upwards to avoid wrong operation.
- If a specular body is present in the background, wrong operation may be caused due to a small change in the angle of the background body. In that case, install the sensor at an inclination and confirm the operation with the actual sensing object.
- Take care that some objects may produce a dead zone right (less than 0.1 m 0.328 ft) in front of the sensor.
