E39-P21

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 Ret- roreflective 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 aDigital Fiber Amplifier.Ordering Information■ Sensor HeadsSensing method Focus Model number RemarksDiffuse reflective Spot E3C-LD11 Mounting a Beam Unit (sold separately) allows the use of line and area beams.Line E3C-LD21 This model number is for the set consisting of the E39-P11 mounted to the E3C-LD11.Area E3C-LD31 This model number is for the set consisting of the E39-P21 mounted to the E3C-LD11.Coaxial retroreflective Spot (variable) E3C-LR11 (See note.)
