E3C-L
DA Series
A-455
E3C-LDA Series
Photoelectric Sensors with Separate Digital Amplifiers (Laser-type Amplifier Units)
E3C-LDA Series
• All seven laser types provide ample
long distance, for the Diffuse Reflective
Model 1.000 mm and for Retroreflec-
tive Models up to 7.000 mm.
• Coaxial Retroreflective Models provide
detection performance equivalent to
through-beam sensors, simplifying
Sensor installation.
• Industry-first variable focal point and
optical axis alignment mechanisms.
Optimize for workpieces and improve
inspection quality.
• Drive the laser with an Amplifier the
same size as a Digital Fiber Amplifier.
