PRECAUTIONS FOR PROPER USE
Refer to p.1458~ for general precautions.
Mounting
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 reected 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.

• 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.
• 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 conrm 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.
• Never use this product as a sensing device
for personnel protection.
• In case of using sensing devices for
personnel protection, use products which
meet laws and standards, such as OSHA,
ANSI or IEC etc., for personnel protection
applicable in each region or country.
