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-prole 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 ampliers, MAXI-AMP™ system CM Series
modulated ampliers, and MB Series ampliers.

Specications, MB Series Ampliers
Hookup to MB Series Ampliers
Banner remote sensors will connect to any MB Series amplier. The
model MRB chassis (shown) has octal sockets for the amplier 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 amplier 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 ampliers 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 amplier.)
3) Always use shielded cables and only connect the shield ("drain")
wire at the amplier.
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.

when all receivers simultaneously see "dark") is possible.
CM Series modules combine power supply, modulated photoelectric
amplier, timing logic (CM5 models), and output relay in a single
compact module. Only an 11-pin relay socket (Banner model RS-11)
is needed to complete the system.
The CM Series contains models with or without programmable timing
logic and with either electromechanical or solid-state relay outputs
(models are listed in the tables, below).
Up to three sensor pairs may be connected to each amplier. Light- op-

WARRANTY: Banner Engineering Corporation warrants its products to be free from defects for a period of one year. Banner Engineering Corporation will
repair or replace, free of charge, any product of its manufacture found to be defective at the time it is returned to the factory during the warranty period. This
warranty does not cover damage or liability for the improper application of Banner products. This warranty is in lieu of any other warranty either expressed
or implied.

WARNING These photoelectric presence sensors and ampliers do NOT include the self-checking redundant circuitry neces-
sary to allow their use in personnel safety applications. A sensor or amplier failure or malfunction can result in either an energized
or a de-energized sensor output condition.
Never use these products as sensing devices for personnel protection. Their use as safety devices may create an unsafe condition
which could lead to serious injury or death.
Only MACHINE-GUARD and PERIMETER-GUARD Systems, and other systems so designated, are designed to meet OSHA and
ANSI machine safety standards for point-of-operation guarding devices. No other Banner sensors or controls are designed to meet these standards, and
they must NOT be used as sensing devices for personnel protection.

RESPONSE SPEED: programmable for 10, 2, or 0.3 milliseconds (10 millisecond setting enhances noise rejection).
MAXIMUM SENSOR LEAD LENGTH: 50' (15m) maximum. To avoid "cable crosstalk", use separate shielded cable for emitter and receiver, or order sen-
sors with extended cable length.
OPERATING TEMPERATURE RANGE: 0 to +50 degrees C (+32 to +122 degrees F).
MICRO-AMP amplier module models MA3-4 and MA3-4P may be
used with this sensor pair. Model MA3-4 has complementary current
sinking outputs. Model MA3-4P has complementary current sourc-
ing outputs.
Model MA3-4 (but not model MA3-4P) may be powered by the model
MPS-15 power supply, as shown in the hookup diagram (right). The
MPS-15 includes a socket for the MA3-4 and has a built-in SPDT
output relay (switchable by the MA3-4 module).
MICRO-AMP modules may also be mounted in a model RS8 wiring
socket and powered from a "remote" power supply. PVC mounting
track is available in 6" and 12" lengths to accommodate multiple MI-
CRO-AMP system components.
NOTE: only one pair of LR/PT300s may be connected to each ampli-
er.
