Digital Fiber Sensor FX-500 Ver.2

Operation keys (setting switch and MODE key) have been renewed to be easy to operate. Also, the color of the keys has been changed from black to light gray to achieve good visibility in dim light.

[Upgraded (Ver. 2)]

When the FX-500 series is used together with our super quality fiber, the incident light intensity variation among units is decreased to only 1/4 of that of conventional models.
By being close to absolute values instead of modified digital values, changes in detection that could not be found in the past can now be monitored.

New fibers developed using a new manufacturing method adopted by our own factory along with a persistent quality control system.
The basic performance of a standard fiber is greatly enhanced!

FX-500 with its high response time contributes to improve productivity.

Performing minute object detection when using a small diameter fiber is now possible with a high response time and longer sensing range.

FX-500 in combination with small diameter fibers which can handle challenging detections, allows long sensing range.

Note: When using FD-NFM2.

FX-500 with its accurate detection catches fractional differences in light intensity, achieving high precision and solving low-hysteresis applications.

The large and high-contrast 7-segment display of high luminance provides clear visibility from a wide angle of view.

The variation in display can be adjusted to random values. This helps to define proper instruction in a work order.

The “four-chemical emitting element”, which we are the first to incorporate to maintain a stable level of light emission, has now become an industry standard.
FX-500 series continues to adopt the same emitting element as well as the “APC (Auto Power Control) circuit” which improves stability in short periods such as when the power is turned on.

This function performs automatic setting to threshold value by checking the incident light intensity at desired intervals in order to follow the changes in the light amount resulting from changes in the environment over long periods (such as dust). This contributes to reduction in maintenance hours.

■Detect deterioration in light intensity (e.g. Useful in dusty environment) Self-diagnosis can be used with the threshold tracking function for added effectiveness.

FX-502(P) / 505(P)-C2 can set Output 2 as a selfdiagnosis output. When the teaching of Output 1’s threshold value is carried out, Output 2 is set concurrently with the setting randomly shifted by the amount of surplus of threshold value. Light intensity deterioration due to fiber breakage or dust accumulation can be notified as an alarm output.

In cases when the incident light intensity is saturated, the light emitting amount can be adjusted to the optimal level by AUTO without changing the response time. This allows stable detection with an optimal S/N ratio and saves energy by controlling the emitting electric current.

Truth table

■Equipped with 5 timer types
A wide variety of timer control operations can be carried out by
fiber sensors only.

Timer period: 0.05 ms to 32 s Output 1 has ON / OFF-delay and ON-delay / One-shot timers are available.

To monitor the sensing of objects, a 4 to 20 mA analog current is output in respond to the digital value of the incident light intensity.

■Edge tracking of film or sheet The meandering path can be monitored as the light intensity changes.

The number of data banks used for saving the setup conditions of the amplifirer is increased to eight. Setup conditions can be saved and loaded to make setup changes easy at a worksite where multiple models are manufactured.

Work efficiency can be improved by operating via PLC output or other external signal.^*
*FX-502(P) can operate via external signal when switching from Output 2 to external input.

■Functions operable by external input

The data that is currently set can be copied and saved all at once for all amplifiers connected together from the right side thanks to the optical communication function.
This greatly reduces troublesome setup tasks and makes setup much smoother.

All FX-500 amplifiers can be used as either a main unit or a sub unit. Just use a main cable or a sub cable to distinguish the two. This reduces the costs of inventory management.

The quick-connection cables enable reduction in wiring. The connections and man-hours required for the relay terminal block setup can be reduced and valuable space is saved.

* Connection of up to 16 units with FX-400 / DPS-400 / LS-400 is possible. * Up to 12 sensors in optical communication.
