Omron E3Z-LT Manual

Laser Photoelectric Sensor with Built-in Amplifier
E3Z-LT/LR/LL
The Most Compact Laser Sensor
The Most Reliable E3Z
■ Excellent quality of E3Z such as the maximum ambient operating
temperate of 55°C, IP67 degree of protection is inherited.
■ Safe and reliable class 1 (JIS/IEC) laser used
■ Excellent detection performance supporting long distance and
low hysteresis
■ Complete Compliance with RoHS
■ Spot diameters can be customized.
Increasing the spot diameter makes optical axis adjustment easier.
Be sure to read Safety Precautions on
page 9.
Applications
Detect the sides of large tiles.
Greatly Enhanced Beam Visibility
for Easier Optical Axis Adjustment of Sensors
Detect chip components on tape.
Optical Customization for E3Z Lasers
That Fit the Application!
The E3Z laser system has an original modular structure. Spot diameters can be customized, as shown in the examples below.
For example, when a through-beam model is used at far range, the optical axis can be easily adjusted by widening the spot, and minute objects
can be easily detected by minimizing the spot at close range. These applications improve product value.
Advanced Optical Technology of the E3Z Laser
Laser beam directional deviation can be suppressed and
spot diameters can be freely customized.
This is achieved through high-precision alignment technology based on LD
and emitter lens modularization.
The lens position can be adjusted inline.

By precisely adjusting the emitter lens in the vertical, horizontal, and depth directions,
alignment can be achieved with minimal directional deviation (to ±1 degree).
