Amplifier Built-in Ultra-compact Laser Sensor EX-L200

Introducing ultra-compact amplifier built-in laser sensor

Amplifier Built-in Ultra-compact Laser Sensor  EX-L200
CE Marking FDA

CE , FDA Approved

Features

Ultra-compact

Due to the customized IC and optical design, high precision detection is fulfilled with directivity and visibility achievable only by laser. The laser adopted is Class 1 (IEC / JIS / FDA) laser that is safe to use, so that there is no need to separate the areas of sensor usage.

Ultra-compact

High precision

Highly accurate detection [EX-L211/L221]

Suitable for positioning and minute object detection

A repeatability of 0.02 mm 0.0008 in or less at a range of from 100 to 200 mm 3.937 to 7.874 in makes this type best suitable for positioning applications (typical, EX-L221). Moreover, it boasts a top-class detection precision in the compact laser sensor category with the gold wire of ø0.01 mm ø0.0004 in.

Dependable technology yields high precision

Incorporating a high-precision aspheric glass lens

Light aberrations are reduced and a high definition laser spot is possible by incorporating a molded aspheric glass lens.

Small receiver aperture for precision detection [EX-L211/L212]

Errant beams are eliminated by the ø0.5 mm ø0.020 in receiver aperture. Only beams entering the aperture are used, making for high-precision sensing.

Stable convergent distance sensing

For sensing when background object presents

Due to convergent distance sensing, the background has very little effect, enabling stable sensing. Sensitivity adjuster allows you to adjust sensitivity to avoid sensing background objects when the distance between the workpiece and background objects is small.

For sensing unevenly-colored workpieces

Able to reliably sense unevenly-colored workpieces.

EASY ALIGNMENT

Easy beam-axis alignment [EX-L211/EX-L212]

Visual positioning is easy due to silhouetting a sensing object against a receiver.

Visually confirm the optimal receiver position, adjusting the beam axis by aligning the objects while watching the red spot on the beam alignment screen. The diagram on the right shows an example with the lead of a mechanical pencil being detected through visual adjustment.

EASY SETTING

Same mounting pitch as ultra-compact photoelectric sensor

EX-L200 series has the same mounting pitch as ultra-compact photoelectric sensor EX-20 series so that the time taken in designing is saved.

ENVIRONMENTAL RESISTANCE

Strong against water and dust with protection structure IP67

The sensor can be used even in environment where water or dust present because of its protection structure IP67.

EASY TO USE

M3 screw used for secure tightening (*1)

The mounting holes have metal sleeves inserted to prevent damage to the sensor due to over tightening of the screws.

Sensitivity adjuster (excluding EX-L212□) (*2)

A sensitivity adjuster of small size is incorporated to offer strong performance in minute detection or high precision detection.

Low current consumption (*2)

The laser light source contributes to low current consumption, as it is approx. 5 mA lower than a LED light source.

Conductor thickness 1.5 times increased to make wiring easier (*3)

The lead wire conductor’s thickness is increased to 0.15 mm2 from 0.1 mm2 of the conventional ultra-compact photoelectric sensor. This makes it easier to perform crimpling work on the cables for better workability. In addition, the tensile strength of the crimpling area has become stronger.

Switchable output operation (*4)

The output operation switching input enables the switching of Light-ON or Dark-ON in one unit. This prevents ordering mistake and reduces the maintenance of spare parts.
