Ultra-compact

67% decreased by volume ratio (comparison with SUNX general-purpose photoelectric sensors)

The customized IC and the new structural design pursue a compact size. An amplifier built-in laser sensor is now offered in a compact body that is in the range of SUNX conventional ultra-compact photoelectric sensors.

High precision

■Min. sensing object ø0.3 mm ø0.012 in (typical) [EX-L211]

The ø0.5 mm ø0.020 in light receiving slit cuts out any unnecessary beam. As only the beam which enters into the slit becomes valid, an accurate and precise detection is possible. This is effective for minute object detection or small difference in level detection. Also, the aspheric surface adopts a glass module lens to deliver a high quality spot beam.

■Suitable for positioning and minute object detection [EX-L221]

A repeatability of 0.02 mm 0.0008 in or less at a range of from 100 mm to 200 mm 3.937 to 7.874 in makes this type best suitable for positioning applications. Moreover, it boasts a top-class detection precision in the compact laser sensor category with its min. sensing object being ø0.01 mm ø0.0004 in.
The same aspheric surface glass lens used in the thru-beam type is adopted to minimize aberration and deliver a high quality beam spot.

Easy alignment [EX-L211/EX-L212]

Beam alignment is carried out by looking at the red spot reflected on the beam alignment screen to match with the actual object. The optimum position can be understood at a glance by looking at the beam alignment screen and stability indicator (green).

Easy setting

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

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

High usability

■M3 screw used for secure tightening

The mounting holes have metal sleeves inserted to prevent damage to the sensor due to over tightening of the screws. It is possible to tighten securely with M3 screws.
(Tightening torque: 0.5 N.m)

■Conductor thickness 1.5 times increased to make wiring easier

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.

■Sensitivity adjuster [EX-L211]

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

■Switchable output operation

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.

■Low current consumption

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