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.
Maximum Load Current of 100 mA
Output control of up to 100 mA is supported for either NPN or PNP
outputs.
Models with Connectors Simplify Wiring and
Maintenance
Using models with connectors allows wiring to be used as it is, with
no need to replace anything but sensors.
Mount Using M3 or M2 Screws
The EE-SX91 can be mounted using M3 or M2 screws, so it can
easily replace an existing compact sensor mounted with M2 screws.
