Basic Information
Introducing ultra-compact amplifier built-in laser sensor
CE,FDA,GB,UKCA Approved
GB : Conforming to 7247.1
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/EN/JIS/GB/KS/FDA) laser that is safe to use, so that there is no need to separate the areas of sensor usage.
Highly accurate detection [EX-L211/L221]
Suitable for positioning and minute object detection
| Model No. (Minute object detection type) | Minimum sensing object (Typical) | Repeatability (Typical) |
|---|---|---|
| EX-L211 (Thru-beam type) | ø0.3 mm ø0.012 in | 0.01 mm 0.0004 in or less |
| EX-L221 (Spot reflective type) | ø0.01 mm ø0.0004 in | 0.02 mm 0.0008 in or less |
*Typical values when the sensitivity adjuster is optimally adjusted.
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 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
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.
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.

Correlation between sensing object size and sensing range
As the sensing object size becomes smaller than the standard size (white non-glossy paper 100 × 100 mm 3.937 × 3.937 in), the sensing range shortens, as shown in the left graph.
(For plotting the left graph, the sensitivity has been set such that a 100 × 100 mm 3.937 × 3.937 in white non-glossy paper is just detectable at a distance of 300 mm 11.811 in.)
Correlation between lightness and sensing range
The sensing region (typical) is represented by oblique lines in the left figure. However, the sensitivity should be set with an enough margin because of slight variation in products.
(The graph is drawn for the maximum sensitirity setting.)
(Lightness shown on the left may differ slightly from the actual object condition.)

Correlation between lightness and sensing range
The sensing region (typical) is represented by oblique lines in the left figure. However, the sensitivity should be set with enough margin because of slight variation in products.
Lightness shown on the left may differ slightly from the actual object condition.
Correlation between material and sensing range (face-to-face)
The bars in the graph indicate the sensing range (typical) for the respective material. However, there is a slight variation in the sensing range depending on the product.
Further, if there is a reflective object (conveyor, etc.) in the background of the sensing object, since it affects the sensing, separate it by more than twice the sensing range shown in the left graph, or adjust the sensitivity adjuster.
Make sure to confirm detection with an actual sensor.

Mounting
Note:The mounting direction of the mounting plate is fixed. Install in a way so that the bending shape is facing the sensor side.
- When mounting this sensor, use a mounting plate (MS-EXL2-2, MS-EXL2-3). Without using the mounting plate, beam misalignment may occur. Also, install the mounting plate in between the sensor and the mounting surface.
- The tightening torque should be 0.5 N·m or less.
Automatic interference prevention function
- Spot reflective type sensor incorporate this function.
Up to two sets of sensor can be mounted closely.
(Thru-beam type sensor does not have this function.)
2 sensor heads can be mounted adjacently.
Note:If two spot reflective type sensor are mounted facing each other, they should be angled so as not to receive the beam from the opposing sensor or to detect its front face.
Others
- Do not use during the initial transient time (approx. 50ms) after the power supply is switched ON.
- In case the load and this sensor are connected to different power supplies, be sure to turn ON the power from the sensor.
- The cable may break by applying excess stress in low temperature.
- Do not allow any water, oil fingerprints, etc., which may refract light, or dust, dirt, etc., which may block light, to stick to the emitting / receiving surfaces of the sensor head. In case they are present, wipe them with a clean, soft cloth or lens paper. Do not use this sensor in places having excessive vapor, dust, etc., or where it may come in contact with corrosive gas.
- Take care that the sensor does not come in direct contact with oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.
- Make sure that the power is OFF while cleaning the emitting / receiving windows of the sensor head.
- This device is using a laser which has high directional quality. Therefore the beam possibly be out of alignment by the mounting condition of this device or distortion of housing etc. Make sure to adjust the beam axe alignment before use.
