glass ber optics
The threaded barrel design of the
LR400 and PT400 permit the con-
nection of any Banner glass ber
optic assembly by using two model
FOF-400 ttings. The sensors are
typically mounted through a 3/8
inch (10mm) diameter clearance
hole, with the FOF-400 fittings
threaded onto them after mount-
ing. Setscrews in the ttings lock
the bers in place, but allow rapid
replacement without disturbing any
electrical wiring.
As the excess gain curves show, the
LR/PT400 combination produces a
high-performance ber optic sens-
ing system. With the amplier's
1 millisecond response time, this
system can be used for almost any
ber optic requirement.
Range: see excess gain curves

The following hookup diagrams include all of the
remote sensors for use with the model MA3-4
modulated amplier module. It is important to
note how the shield wire of a remote sensor is
wired. The shield wire is the uninsulated wire
in each sensor cable. Failure to connect the
shield as shown may result in false operation of
the amplier. When wiring emitters, it is good
practice to connect the positive wire rst. LEDs
are sensitive to application of the wrong voltage,
and can easily be destroyed.
NOTE: only one sensor may be connected to
each MA3-4 amplier.
Sensor Hookup Diagrams for MA3-4 MICRO-AMP Modules (continued on
page 6)
NOTE: Shield wires must be connected as shown to avoid cable crosstalk.
