Introducing ultra-compact amplifier built-in laser sensor


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 / GB) laser that is safe to use, so that there is no need to separate the areas of sensor usage.del.

* Typical values when the sensitivity adjuster is optimally adjusted.

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 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.


Same mounting pitch as ultra-compact photoelectric sensor
Visual positioning is easy due to silhouetting a sensing object against a receiver.
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.


Strong against water and dust with protection structure IP67
Visual positioning is easy due to silhouetting a sensing object against a receiver.
The sensor can be used even in environment where water or dust present because of its protection structure IP67.


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.
(Tightening torque: 0.5 N.m)
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.

Note 1: The model No. with “E” shown on the label affixed to the thru-beam type sensor is the emitter, “D” shown on the label is the receiver.
Note 2: The sensing range is the value for RF-330 reflector. The sensing range represents the actual sensing range of the sensor. The sensing ranges itemized in “A” of the table below may vary depending on the shape of sensing object. Be sure to check the operation with the actual sensing object.

Note 3: Refer to OPTIONS for the polarizing filter PF-EXL2-1 and the refl ector RF-210.
