 Designed for general industrial use, not for safety equipment.
 Do not connect this device to AC power. Doing so might cause rupture or burnout.
Warning
•
If a cable extension is necessary, use wire at least 0.3 mm
2
in
cross-sectional area and at most 100 m long.
•
If the cable of photoelectric switch are laid in the same conduit as
high-voltage or power lines, inductance may cause malfunction or
damage. Isolate the photoelectric switch's cable or lay it in a
separate conduit.
•
When using a commercially available switching regulator, ground
the frame ground and ground terminals. If used without grounding,
switching noise may cause faulty operation.
•
When using a load which generates an inrush current above the
switching capacity, such as a capacitive load or incandescent
lamp, connect a current-limiting resistor between the load and the
output terminals.
Otherwise, the output short-circuit protection function may be
activated.
Thru-scan model and polarized retroreflective model
1.
Move the emitter and receiver (Main body and reflector in case of a
retroreflective model) up, down, right, and left, and then align them in
the center of the area where the green stable-operation indicator
lights up.
2. Check switch operation using a target object then use the Auto
Adjust button to adjust the sensitivity setting.
Diffuse-scan model
1. Mount the photoelectric switch pointing toward the desired
detection position.
2. Check switch operation using a target object then use the Auto
Adjust button to adjust the sensitivity setting.
•
Tighten the mounting screws to a maximum torque of 0.8 N·m.
•
After the power is turned on, the switch starts to operate in 60 ms
at most (80 ms for HP7-C).
•
For outdoor use, put inside a case, etc., To prevent direct exposure
to sunlight and rain water.
•
Avoid locations with strong vibration or impact. They may cause
optical axis misalignment.
•
Shield the lens from water and oil. Water or oil on the lens can
cause faulty operation.
•
Do not expose to chemicals (Organic solvents, acids, alkalis).
•
Use a cover or change the mounting direction to ensure correct
switch operation if there is heavy interference from ambient light.
•
When used in a very dusty environment, be sure to take
countermeasures to keep dust away from the lens surface by using
a sealed case or air purging.
•
Even when oil-resistant cable is used, do not use in a location
subject to continuous splashing by water or oil, or where the unit is
immersed in liquid. Ensure that the end of the cable is not subject
to splashing by water or oil.
•
A bend in the cable immediately after it exits the device should
have a radius of a least 30 mm. Also, avoid use in which the cable
receives repeated bending stress. Do not apply a force of 50 N or
higher (30 N or higher for low-temperature cable types).
•
Do not pull the cable with excessive force (> 50 N). cable
disconnection can cause burnout. Do not apply a force of 50 N or
higher (30 N or higher for low-temperature cable types).
•
Photoelectric switches are assembled with precision. Never strike
with another object. Especially if the lens surface is scratched or
cracked, switch performance may decline.
Handle with care.
•
To clean the lens or reflector, wipe lightly with a soft, clean cloth or
cloth moistened with water. Do not use an organic solvent such as
alcohol, benzene, acetone, or thinner.
•
When multiple photoelectric switches are used close together,
mutual interference may occur. After installation, check the
operation carefully before use.
•
Standard cable might get hardened under 0°C. Do not bend or
apply shock / vibration under 0°C. Low temperature cable is
available.
•
Switch might not reliably detect highly reflective objects or objects
that disrupt polarization (ex.: Object covered with transparent film).
In such a case try the following countermeasures:
1.
Handling precautions
2.
Wiring precautions
3.
Adjustment method
Sample countermeasures
Mount the switch at an angle to the target object.
Increase the distance between the switch and
the target object.
Tune the switch without a workpiece.
