Digital Fiber Sensor FX-250

Features

Overwhelmingly easy to understand, Organic EL display

The clear, high-visibility flat panel ensures easy operation to reduce setting time and minimize setting errors. It contributes to improved efficiency on the production site.

Enables intuitive operation without referring to the manual
[Reduces setting time]  [Minimizes setting errors]

Compact body

The compact body can be easily mounted to small equipment and robotic hands with limited installation spaces.

[New function] Smart limit teaching
Simultaneous execution of teaching and circumvention of saturation

Teaching is executed only with two pushes of a button, and this also achieves circumvention of saturation simultaneously.
There is no need for separate adjustment of the light emission amount, thus contributing to reduction of setting man-hours.
* Only when limit teaching is used

Incident light intensity adjustable in 100 increments

The incident light intensity can be varied in 100 steps to allow flexible and precise adjustment of incident light intensity even when the incident light becomes saturated due to installation in a close distance or during detection of a transparent or very small workpiece, thus realizing stable detection.

Detection of metal wire

Detection of transparent sticker on transparent sheet

Alternate frequency interference prevention function

In the case the fibers are arranged side by side, mutual interference can be prevented by setting different light emission frequencies (4 settings).

* Response time varies depending on light emission frequencies.
* When the alternate frequency interference prevention function is used, up to four fiber head units can be mounted in contact with each other.

Zero-set function

When a reflective type fiber is used, offsetting the incident light intensity to "0" with no workpiece present enables confirmation of only the change caused by the detected object.
When multiple amplifiers are mounted side by side, all displayed values can be set to "0."

Equipped with three types of timer function

A variety of timer control operations can be carried out only by fiber sensors.

Timer period setting range: 1 to 9,999 ms, in 1-ms increments (default setting: 1 ms)

Display and indicator can be set to OFF.

Since the digital display and large output indicator can stay turned off during use, the FX-250 series is suitable for use with equipment that can be affected by light or heat.

Stable detection over long periods and short periods
Stabilization of light emission amount

The built-in APC circuit stabilizes the short-time fluctuation of the light emission amount at the time of power on and the four-element light emitting diode ensures stable emission over long periods.

■ APC circuit

When power is turned on or when the temperature changes, the sensor's light emission amount fluctuates and causes instability of output. To solve this problem, the APC circuit controls the light emission amount to ensure short-term emission stability.

■ Four-element light emitting diode

When a conventional LED operates for a long period of time, the LED becomes damaged due to heat or the light intensity decreases due to oxidation. The four-element light emitting diode suppresses degradation of the light emitting element to the maximum extent and ensures long-term emission stability.
