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.
