E3Z Laser Models

Laser Photoelectric Sensor with Built-in Amplifier

E3Z-Laser

Compact 
photoelectric sensor 
with LASER light

The E3Z LASER sensor in compact

plastic housing features visible LASER

light for precision positioning and detec-

tion applications.

• Visible LASER light for precision posi-

tioning and small object detection 

• High power LED for high functional 

reserve

Features

Through-beam and Retroreflective Sensors

Greatly Enhanced Beam Visibility for Easier Optical Axis Ad-
justment of Sensors

• The optical design maximizes the linear propagation of la-

ser beams. Red laser beams (class 1) can be precisely 
aligned on the targeted position.

• The functional reserve of the rated through-beam sensing 

distance of 60 m provides sufficient allowance, enabling 
Through-beam Models to be used reliability even in dusty 
environments.

Reliable Detection of Small Objects and Narrow Gaps with the
Small Spot

• The spot diameter for Through-beam and Retro-reflective 

Models is 5 mm (a typical example at 3 m), making it possi-
ble to detect small workpieces at long distances.

• The sensing distance for Retro-reflective Models is 15 m 

(when an E39-R1S Reflector is used). This is the longest 
leeway in the industry.
