Downsizing
• Ultracompact and Thin Photoelectric Sensor with Built-in
Amplifier
• Easy optical axis adjustment with emitter fluctuation of ±2% max.
for Through-beam Models.
• Product lineup includes Coaxial Retro-reflective Models that
support positioning applications.
• Product lineup includes BGS* Reflective Models unaffected by
background (E3T-FL1@/-FL2@).
• Product lineup of models with a variety of connection
specifications.
(e.g., robot cable and Smartclick pre-wired connectors)
* BGS (Background Suppression) technology prevents detecting background objects.
Be sure to read Safety Precautions on

Features
E3T-SR4@
: Retro-reflective Sensor with Enhanced
Compactness and High Performance
• Perform detection from a small hole.
With a coaxial optical system, the lens diameter is only 2 mm.
Sufficient incident light is obtained even through a small hole.
The Coaxial Retro-reflective Sensor can be used for reliable application with positioning.
• Improved Stability of Short-distance Detection
A detection distance as short as 10 mm can be used with a Tape Reflector.
Detection is stable through a hole whether the distance is 10 mm or 100 mm (except in combination with the
E39-R4).
E3T-FL1@/-FL2@: The Slimmest BGS (Background Suppression) Reflective Photoelectric
Sensors in the World
Ultra slim at 3.5 mm and
black/white error of only
15%.
For example, the E3T-
