FX-311 SERIES Manually Set Fiber Sensor

Long-range sensing made possible with built-in optical lens
For the first time in the industry, an optical 'double coupling lens' has been
incorporated directly into the fiber sensor itself. This lens maximizes the light
emission efficiency, resulting in a tremendous improvement in the sensing range.
Sensingranges with small diameter fibers and ultra-small diameter fibers, which have
become very popular in recent years due to the miniaturization of chip components,
have been increasedby 50 % over previous values achieved with other amplifiers.

Stable long-term sensing
The newly developed four-chemical emitting element that uses the
FX-311(red LEDtype) suppresses changes over long periods of time as much as
possible, so that a stable light emitting level is maintained. There is very little
element deterioration so that stable and accurate sensing can be maintained over
long periods.
