
Do not drop the product. Otherwise, the product may be damaged, lead to failure and the performance
will be degraded. Injury may also be caused.
2.2 Operating environment
 Make sure that SE2L’s operating environment is within the stated specification (temperature, humidity,
vibration, ambient light, etc.)
 Do not use or mount SE2L near devices that could generate strong electromagnetic waves as it could
affect the operation of SE2L.

Do not use or mount SE2L in dusty, smoky, or misty environments, or where corrosive substances are
present. Operating under such environments may decrease the detection capacity of SE2L.

This product is for indoor use only.
2.3 Installation of SE2L
 Install SE2L on a firm surface or structure to avoid displacement. Also, do not step on or hung on SE2L
after installation.
 SE2L should be firmly mounted using the screws (recommended torque for screws is 3N
･
m). Shock
and vibration should not loosen the mounting. Detection may fail if actual protection zone differs from
the intended zone due to displacement of SE2L.
 Safety distance should be determined before installing SE2L. User must verify the function of SE2L
after installation by placing a test piece at all the positions of protection zone (refer to chapter 4 for the
details on the safety distance calculation for various applications).
 When installing the SE2L, protective materials such as guards or light curtain should be used to prevent
any passage into the hazardous area.
 Reset switch used for interlock, muting and override function should be mounted at a location away
from the protection zone.
 Mutual interference can occur when identical SE2Ls are mounted at the same detection plane. Refer to
chapter 5 for countermeasures to avoid mutual interference.
 SE2L should be mounted at the location which has sufficient space for maintenance.
 Do not add any protective materials such as, glass and transparent cover, in front of the optical window.
This could lead to loss of detection capability of the SE2L.

Minimum detectable width varies with the distance. Refer to chapter 10 for details.
2.4 Wiring
 Switch off all the power supplies during wiring.
 When a converter is used for supplying the power, make sure it fulfills the following requirements.
 A rated output voltage within the range of 24V DC ±10% (SELV circuit, Category II).
 Reinforced insulation or double insulation for the primary and secondary circuit.
 Holding time of the output should be above 20ms.
 The power supply complies with the requirements of electromagnetic compatibility
