Photoelectric Sensor with Separate Digital Amplifier (Laser-type) E3C-LDA CSM E3C-LDA DS E 4 2 Variable Laser Beam for Spot, Line, or Area Detection Long-distance detection (diffuse reflective: 1 m, retro-reflective: 7 m). Beam shape selectable from spot, line, and area types to match various applications. Adjustable spot diameter. Adjustable optical axis. The E3DC-LDA0, which supports the EtherCAT Sensor Communications Unit and the CompoNet Sensor Communications Unit, is also included in product lineup. Refer to Safety Precautions on page 9. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Features Diffuse Reflective All three beam types provide ample long-distance Sensing Model distance of detection of 1,000 mm. 1 m. Three beam types means a wider variety of applications. Spot, Line, and Area Types At 1,000 mm: Minimum spot diameter of 950 m Suitable for various applications without any additional costs. Variable Focal Point Mechanism Mount Beam Units to a Spot Type Sensor to convert to Line or Area Type. Spot diameter can be adjusted to Optical axis alignment range: enable ultra-high-precision Approximately 2 positioning. Optical Axis Adjustment Mechanism Spot Type The sensor detection point can be easily changed. E3C-LD11 8 mm - 0.2 mm - 3.5 mm (VR minimum) (VR median) (VR maximum) At distance of 150 mm 7 mm - 28.5 mm - 33 mm (VR minimum) (VR median) (VR maximum) Line Type E3C-LD21 5 to 15 mm (VR minimum) (VR maximum) 5 to 33 mm At distance of 150 mm (VR minimum)(VR maximum) Area Type E3C-LD31 Coaxial Retroreflective Sensing Easy Sensor Installation and Sensing Characteristics distance of Model Equivalent to Through-beam Sensors. 7 m. Variable Focal Point Mechanism Optical axis alignment range: Approximately 1 to1.5 Optical Axis Adjustment Mechanism At 1 m: Minimum spot diameter of 0.8 mm E39-R13 Spot, Line, and Area Types Spot Type Coaxial Optical System E3C-LR11 The coaxial optical system and laser beam allow high-precision detection. The built-in MSR Function inhibits the effect of reflected light from the workpiece. 1E3C-LDA Ordering Information Sensor Heads (Dimensions page 12, 13) Sensing method Appearance Beam shape Model Remarks Spot Mounting a Beam Unit (sold separately) allows E3C-LD11 2M (variable) the use of line and area beams.
