Photoelectric Sensor with Separate Digital Amplifier (Laser-type)E3C-LDA - 1

Photoelectric Sensor with Separate Digital Amplifier (Laser-type) 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 Model ■ All three beam types provide ample long-distance detection of 1,000 mm. Three beam types means a wider variety of applications. ■Spot, Line, and Area Types At 1,000 mm: Minimum spot diameter of 950 µm 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. Optical axis alignment range: Approximately ±2° Spot Type Spot diameter can be adjusted to enable ultra-high-precision positioning. ■Optical Axis Adjustment Mechanism The sensor detection point can be easily changed. 8 mm - 0.2 mm - 3.5 mm (VR minimum) (VR median) (VR maximum) (VR minimum) (VR median) (VR maximum) Line Type Area Type Coaxial Retroreflective Model ■ Easy Sensor Installation and Sensing Characteristics Equivalent to Through-beam Sensors. ■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 ■Spot, Line, and Area Types Spot Type ■Coaxial Optical System The coaxial optical system and laser beam allow high-precision detection. The built-in MSR Function inhibits the effect of reflecte
