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.

Values are sensed for white paper. 2. These values apply when a E39-R12 Reflector is used. The MSR function is built-in. The reflected light from the object being measured may affect the sensing accuracy, so adjust the threshold value before use. 3. The beam radius is the value for the middle measurement distance and indicates a typical value for the middle sensing distance. The radius is defined by light 2 intensity of 1/e (13.5%) of the central light intensity. Light will extend beyond the main beam and may be affected by conditions surrounding the object being measured. 4. The E3C-LR12 has a fixed beam size (the focus point cannot be changed). 2 E3C-LDA Series Photoelectric Sensors with Separate Digital Amplifiers (Laser-type Amplifier Units)
