FX-300 Fiber Optic Sensors
The FX-300 series of digital fiber optic sensors offers a wide range of sensing possibilities in a compact, high-performance
unit. Three types are available for optimal application coverage including the standard type (FX-301), high-function type (FX-
305), and the high-speed type (FX-301-HS).
The core of the FX-300 series revolves around five main concepts for superior sensor performance:
High Stability
SUNX has developed a system that drastically increases the long and short term stability of their FX-300 series fiber
optic sensors.
Superior Performance
The FX-300 series has incorporated several functions that improve on the performance of pervious models.
Easy Operation
The FX-300 series was designed around ease of use. The incorporation of a user-friendly jog-dial simplifies operation
and maintenance. Beginners and advanced users alike will benefit from the intuitive programming and operation, thus,
keeping the learning curve to a minimum.
Easy Maintenance
SUNX has developed several new features/accessories that simplify sensor maintenance so you spend less time
configuring the sensor and more time using it.
Four-Chemical Element LED: Primary to that system is the adoption of a four-chemical element LED light source
that demonstrates unmatched stability in light output over time.
Auto Power Control (APC): To enhance the stability further, SUNX also has integrated an 'Auto Power Control
(APC)' circuit which combats short-term fluctuation in light emission due to ambient conditions.
Double Coupling Lens: These two features are then used to their full advantage by adding a double coupling lens
to focus the emitted light, impressively increasing the overall efficiency and detection distance of the sensor.
Light Output Level Selection: The new light output emission function allows for the user to adjust the light output
intensity without effecting the response time of the sensor. This is great for applications that are inhibited by close
range sensing that result in an over-saturation of the sensor.
Large Four Digit Display: The large 4-digit display also increases the saturation point to 9999 to provide better
sensing at close range.
High Speed: Ultra fast response times are also available with the high-speed type, FX-301-HS. Demonstrating a 35-
microsecond response time, this can handle the most demanding speed requirements.
New Operating Modes: By using the window comparator mode and the differential sensing mode, users can
now perform sensing operations that once needed two sensors and complex threshold settings.
Five Timer Types: In addition to the ON-Delay, OFF-Delay, and ONE-SHOT timers that are found in many
conventional fiber sensors, the SUNX FX-300 series incorporates combination timers: ON+OFF Delay and ON-
Delay+ONE-SHOT
Multi-Purpose Dual Output:Two independent discrete outputs are available (FX-305) so that one sensor can be
used to control tasks that previously required two sensors. In addition, the secondary output can be used for simple
self-diagnosis or an alarm output so that ease on maintenance is improved.
Mode NAVI: Six easy-to-see indicators surround the main display allowing quick and easy confirmation of the
operating mode. Also, the threshold value can be conveniently checked at the touch of a button.
Key Lock Function: The key lock function is a very useful feature in avoiding accidental changes to the sensor
settings. The jog switch as well as the mode button is disabled to prevent any unwanted modifications.
New Communication Unit: The new SC-GU1-485 communication unit allows for complete remote access to
sensor settings. Functions such as teaching and data bank switching can now be performed via a PLC. All sensor
