Fiber optic sensing is often
the answer when, due to space
or environmental limitations,
the sensor itself cannot be
placed at the actual sensing
position. These sensors' pow-
erful modulated infrared
beam is compatible with all
Banner glass fiber optics in
the opposed, retroreflective,
and diffuse sensing modes
(see Banner product catalog).
Sensor/fiber interface is wa-
terproof to maintain complete
sensing system moisture re-
jection.
Repeatability:
1.3ms (dc models);
2.6ms (ac models)

OPPOSED FIBER OPTIC
MODE (glass fibers)
These opposed mode fiber optic emitter-receiver pairs are used where the
separation between emitting and receiving fibers is greater than a few feet, or
where it is inconvenient to run both fibers from a single VALU-BEAM sensor.
These models have a watertight o-ring sealed sensor/fiber interface, and are
compatible with all Banner glass fiber optic assemblies (see product catalog).
