Manual

The LR300 emitter and PT300 receiver are compact, totally-encapsulated opposed mode remote sensors whose right-angle design, ex-
tremely small size, and excellent operating characteristics make them ideal for many sensing applications. Mounting and alignment are
very simple, due to these sensors' wide eld of view. The LR300 and PT300 easily mount in place by means of their through-mounting
holes and two #4 screws.
"300" series sensors are fully encapsulated with hermetically sealed lenses to eliminate internal condensation, and have extremely ex-
ible, low-prole 2-wire cable. Units may be washed down without damage. Identical optical performance in different housing styles
is available in models LR/PT 200, 250, and 400 (see Banner product catalog).
The minimum object size required to break the beam of the LR300/PT300 opposed mode sensor pair is 1/8-inch. These sensors are
designed for use with Banner MICRO-AMP
®
system MA3-4 and MA3-4P modulated ampliers, MAXI-AMP™ system CM Series
modulated ampliers, and MB Series ampliers.

Hookup to MB Series Ampliers
Banner remote sensors will connect to any MB Series amplier. The
model MRB chassis (shown) has octal sockets for the amplier and a
BR-2 relay (supplied) and provides power for the sensors and ampli-
er. Up to four sensor pairs may be connected to one amplier for
light-operated OR or dark operated AND operation. In multiple-sensor
hookups, receivers are wired in parallel and emitters are connected in
series (see example for CM Series modules, next page).
Several MB Series ampliers are available. Each provides a different
output logic function. Refer to the Banner catalog for more informa-
tion.
Chassis models with additional octal sockets are also available. Other
types of output devices, including solid state relays, may be ordered
(see Banner catalog).
4) When splicing, never combine emitter and receiver wires into a
common cable. (The result will be electrical "crosstalk" within the
cable, which causes a "lock-on" condition of the amplier.)
3) Always use shielded cables and only connect the shield ("drain")
wire at the amplier.
2) Avoid running remote sensor cables through areas of known ex-
treme electrical interference (electrical "noise").
1) Avoid running remote sensor cables in wireways together with
power-carrying conductors.
