Photoelectric Sensors with Separate Digital Amplifiers (Laser-type Amplifier Units)

E3C-LDA Series

• All three beam types provide ample long-distance

detection of 1,000 mm for Diffuse Reflective Models.

• 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.
