This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use this product under ambient conditions that exceed the
ratings.
● Design
Influence of Surrounding Metal
When mounting the Sensor within a metal panel, ensure that the
clearances given in the following table are maintained. Failure to
maintain these distances may cause deterioration in the performance
of the Sensor.
Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
● Mounting
Handling
• Do not use the Sensor outdoors.
• Do not wire the Sensor alongside a high-tension or power line.
• Do not use portable telephones or transceivers near the Sensor. Be
sure to ground the Mounting Brackets.
• Do not use the Sensor in an environment where it will be exposed
to chemicals, particularly chemical solutions or oxidizing acids.
Influence of Static Electricity
Be sure to discharge static electricity before detecting objects that are
greatly affected by static electricity.
Mounting the Sensor
The maximum tightening torque that should be applied is 0.54 N·m.
Cable between Sensor and Amplifier Unit
• Be sure that the bending radius of the cable is more than 5 mm.
• Use the XS3W-M421-40@-R cable with connectors (M8-screw
mounting) as the extension cable.
The maximum cable length is 3 m (extension section: 2 m).
Sensitivity Adjustment
For information on the sensitivity adjustment, refer to Technical Guide
for Operation for information for Proximity Sensor.
