Laser Photoelectric Sensor with Built-in Amplifier
BGS Models
Long-distance Sensing at 300 mm (White Paper)
A Low Black/White Error for Applications with Mixed Colors
• A black/white error as low as 5% makes detection and op-
eration more stable.
Easy Detection of Small Workpieces and Minor Differences in
Levels with the Small Spot
• Stable detection is possible with no influence from a glossy
background frame.
• The spot diameter for BGS models is 0.5 mm (typical exam-
ple at 300 mm). Combined with an hysteresis of only 5%,
even minute differences can be detected.
• Models with a response time of 0.5 ms (E3Z-LL
@
3/
@
8) are
available as standard models for fast-moving objects.
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.
(Patent pending.)
Laser Diagram Conceptual Diagram
By precisely adjusting the emitter lens in the vertical, horizon-
tal, and depth directions, alignment can be achieved with min-
imal directional deviation (to ±1 degree).
