คุณสมบัติ

Can detect any mark!

Coaxial reflective optics and a sharp 1 x 5 mm 0.039 x 0.197 in spot enable high precision sensing. Stable detection of marks is possible.

Automatic optimal LED selection function

The 3 colors of the R・G・B LEDs are optimally selected according to the color combination. With the LX-100’s Mark mode, the built-in “Automatic optimal LED selection function” automatically selects the LED for the largest contrast (S / N ratio) between the mark and base (non-mark area) to ensure optimal sensing. For more stable detection, the sensor makes selections according to the contrast and not according to the reflected light variation between the mark and base (non-mark area).
[The example on shown below deals with reflected light on packing film. Great figures are indicated for the blue LED’s light amount ratio and, for even more stable sensing, the blue LED effectuates this mark sensing.]

Two detection modes can be selected from to suit the application

Mark mode [Ultra-high-speed response]
This sensing mode automatically selects a single color from the 3 R・G・B LEDs to achieve an ultra-quick 45 μs response time. The automatic optimal LED selection function automatically selects the LED that is most suitable for the sensing. This function is perfect for ultra-quick sensing.

Color mode [High precision discrimination]
All 3 R・G・B LEDs light up and high precision mark color discrimination occurs using the R・G・B reflective light ratio. This function enables effective detection of films with patterns around the area of the mark.

* You can select the Mark mode or Color mode through key operation.

High precision mark color discrimination

The Color mode on the LX-100 series utilizes all 3 R・G・B LEDs to determine the R・G・B ratio of the mark color. The built-in 12-bit A/D converter enables high precision 1/4,000-resolution judgments. The figure below is a graphic description of this process.

Its digital display makes settings easy! Numerical control of the settings is possible

The 4-digit digital display enables easy verification of received light from marks and base (non-mark area). Also, the threshold value can be controlled numerically enabling setting indication easily. Displaying the direct code enables settings verification. This function is handy for remote maintenance.

Even beginners can quickly master MODE NAVI operation

The sensor’s basic operations are represented by 6 indicators (MODE NAVI). The user can check what mode the sensor is presently in with a quick glance making operation simple.

Sensing status digitally controllable

The sensing status, displayed numerically, can be verified at a glance. Also, the sensor settings for each type of packing film can be digitally indicated.

Direct codes enable settings verification at a glance

The settings for the LX-100 series sensors are displayed using a 4-digit direct code. Direct codes enable easy setting verification and maintenance by phone.
Direct code table (D-Code)

The sensor setting modes can be verified by a 4-digit code (D-Code). The table below shows a list of all available codes.

Notes:
1) In Mark mode, L-ON / D-ON is automatically set in the sensor. For example, with 2-level teaching, press the ON key at the targeted mark and press the OFF key at the base (non-mark area). When doing so, the operator does not have to consider L-ON / D-ON.
2) Sensing accuracy can be set to either FINE (standard) or COARSE.
3) The percent display is only enabled in Mark mode.
4) ECO mode is a function that reduces power consumption by turning off the digital display in the event that no button operations are made for a predetermined time (approx. 10 sec. or more) in RUN mode. Press any button to turn the digital display on again.
5) The turn mode is a function that reverses the digital display making it easily to be viewed in the event that the sensor installation renders the display up-side-down.
* Default setting: D-code = “0004”.

Super simple teaching

Press the ON button at the targeted mark.
Here is an example of the most basic setting method “2-level teaching”.

External teaching possible
Teaching is possible through external input using an operation panel or touch panel even on hard-to-reach color mark sensors located inside an equipment.
Also, models can be interchanged easily.

Other teaching methods
-Full-auto teaching: In Mark mode, teaching is effective without stopping the sensing object.
-1-level teaching: In Color mode, the color detected is aligned by the spot and teaching is effective.

Compact design for significant space savings

High precision sensing and multiple functions are all packed in a compact W57 x D24 x H38 mm W2.244 x D0.945 x H1.496 in body.
Cable and plug-in connector types are available depending on the equipment used.
These sensors can be easily introduced to existing facilities.

Key lock function

The key lock function enables input operation control that prevents mistaken changes in the sensor settings.
Other detailed settings include “RUN adjust”, allowing threshold value adjustment only, and “RUN teaching”, allowing teaching operation only.
If the sensor is set to “RUN adjust” or “RUN teaching”, adjustment and teaching are possible having the sensor remained in RUN mode.
