Features
A Compact Size and Choice of Five Models
for a Wide Range of Applications
Select any of five models to minimize the space required.
Flexible Robot Cables: Standard on All Models
Robot Cables are effective for moving parts, and are provided as
standard equipment with all models.
Both Light-ON and Dark-ON Outputs
Both light-ON and dark-ON outputs are provided on all models,
allowing outputs to be switched by simply changing the wiring
according to the application.
Indicator Visible from Many Directions for
Installation in Any Location
Compact NPN and PNP Output Models
Both NPN and PNP output models are available for use according to
system requirements.
The light indicator can be checked from up to four directions.
Safer Operation with Built-in Power Supply
Reverse Polarity Protection
The built-in power supply reverse polarity protection protects against
reverse connection of the power supply or outputs for safer operation
at the assembly site.
