EQ-34W
Automatic interference prevention Mechanical 2-turn adjuster with indicator Waterproof
The EQ-30 series is the first fixed-
focus sensing reflective type sensor to
incorporate an automatic interference
prevention function so that two sets of
sensors can be installed close together
or facing each other.
It features a mechanical 2-turn dis-
tance adjuster with an indicator that
shows the set distance at a glance.
It has IP67 protection. It can be used in
places splashed with water.

Note: However, take care that if it is exposed
to water splashes during operation, it
may detect a water drop itself.
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)
Principle of fixed-focus sensing with 2-segment photodiode
Normal reflective type sensors
operate by sensing the variation in
the amount of incident beam.
However, the fixed-focus 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.
