Incident light intensity and threshold value are displayed simultaneously

The incident light intensity and threshold value can be checked at the same time with no operations needed. In addition, no complex mode settings are needed when the values are adjusted.

Easy-to-understand operating panel layout

The threshold value adjuster and operation mode switch are large and easy to see, and they can be operated with the same sensitivity as general-purpose photoelectric sensors. Functions which are not commonly used can be operated using a non-obtrusive setting switch.

Adjustment variations according to the individual have been eliminated

Accurate control of the adjuster threshold values by using numerical values is possible due to the digital display. This allows anybody to perform the same settings.

Threshold values can be changed smoothly

This sensor uses the R.S.S.* adjuster with a compact encoder inside. The sensitivity amount changes depending on the rotation speed of the adjuster, so that adjustment can be carried out speedily.

Large endless adjuster

Standard screwdrivers can be used to turn the adjuster as well as precision screwdrivers. In addition, an “endless” mechanism is used which eliminates the possibility of any damage being caused by turning the adjuster too far.

FX-412 can be turned by finger!

The adjuster can be turned directly by finger, without the need for a screwdriver

Beam power greatly increased to give strong performance under adverse environments [Red LED type]

The beam power has been greatly increased. This means a longer sensing distance and less trouble from problems such as dust. These sensors have ample performance for workplace needs.

Three types are available, with red, blue and green light

Different sensors can be selected to suit the application.

Color combinations that can be discerned during mark sensing

Improved stability over both long and short terms [Red LED type]

The red LED type sensors have a “four-chemical emitting element” which maintains stability of light emissions for long-term operation. Furthermore, all models have an “APC (Auto Power Control) circuit” which improves stability at times such as when the power is turned on. These features improve overall stability compared to previous models.

Excellent workability and ease of maintenance [Connector type]

The same quick-connection cable that is used for sensors such as the FX-300 series of digital fiber sensors is used. This means that they can be used together with other types of sensors such as laser sensors, and the number of power supply cables can be reduced.

The sensors can be connected together with other sensors such as the FX-300 series of digital fiber sensors and the GA-311 of inductive proximity sensors. In addition, the SC series of sensor PLC connection units with MIL connector compatibility can also be used to further reduce the amount of wiring.

Contributing to device miniaturization

This fiber sensor is the smallest among the dual digital display types, contributing to device miniaturization.

Ideal for dealing with saturation / Light-emitting amount selection function [Red LED type]

In cases where the incoming light level can become saturated, such as during close-range sensing or when sensing transparent or minute objects, the sensor’s lightemitting amount can be adjusted to provide more stable sensing without changing the response time.

Equipped with 3 types timers

Equipped with OFF-delay / ON-delay / ONE SHOT timer.
(Timer period: 1 to 3 sec. approx.)

Digital display upside-down / off function

The digital display can be turned upside-down if required to suit the setup location. In addition, a stability indicator is also provided, so that the amount of light-receiving excess can be checked even when the display is turned off.

Interference prevention for up to 8 sets fiber heads (for U-LG)

The optical communication function allows up to a maximum of eight sets of fiber heads (four sets for FAST and STD settings) to be installed in contact with each other without mutual interference occurring. (Set automatically when power is turned on.)

Hold function

Peak and bottom hold values for the incident light intensity can be displayed. This is useful for checking the incident light intensity during tasks such as drop detection.
In addition, the peak and bottom values can be checked while looking at the threshold value, which makes adjustment much easier.

Key lock function prevents wrong operation

This prevents the operator from changing the threshold value by mistake.
