Opposed Mode
Remote Sensor Pair
Banner remote sensors will connect to any MB Series amplifier. The
model MRB chassis (shown) has octal sockets for the amplifier and a
BR-2 relay (supplied) and provides power for the sensors and ampli-
fier. Up to four sensor pairs may be connected to one amplifier 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 amplifiers are available. Each provides a different
output logic function. Chassis models with additional octal sockets
are also available. Other types of output devices, including solid state
relays, may be ordered (see Banner catalog).

POWER SUPPLY REQUIREMENT: 12-18V dc at less than 100mA,
exclusive of load.
EXCESS GAIN
BEAM PATTERN
The LR400 emitter and PT400 receiver are compact, totally-encapsulated opposed mode remote sensors whose threaded barrel design
and excellent operating characteristics make them ideal for use on small conveyors and similar applications. Mounting and alignment
are extremely simple, due to these sensors' wide field of view. The LR400 and PT400 mount through 3/8" (9,5mm) clearance holes,
and are secured by two steel jam nuts (included).
The minimum object size needed to break the beam of the sensor beam is 1/8-inch. Optional lenses provide extended sensing range
and/or higher excess gain. Identical optical performance (for unlensed sensors) is available in different housing styles in models LR/
PT200, 250, and 300 (see Banner catalog). LR/PT400 series sensors may be adapted for use with fiberoptics via the accessory FOF-
400 fiber adaptor.
These sensors may be used with Banner MICRO-AMP
®
MA3-4 and MA3-4P modulated amplifiers, MAXI-AMP™ CM Series modu-
lated amplifiers, and MB Series amplifiers. The hookup information below applies to all LR/PT400 series sensors, including: LR400HF,
HFSB, SS, V, VG, VH, and PT400F, SB, and SS.

1) Avoid running remote sensor cables in wireways together with
power-carrying conductors.
Wiring rules:
2) Avoid running remote sensor cables through areas of known ex-
treme electrical interference (electrical "noise").
3) Always use shielded cables and only connect the shield ("drain")
wire at the amplifier.
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 amplifier.)
RANGE: up to 8 feet in opposed mode (see excess gain curve); up
to 110' possible with optional L16 lenses.
EFFECTIVE BEAM: 0.14 inch (3.6 mm) diameter
RESPONSE SPEED: a function of the amplifier (see below)
OPERATING TEMPERATURE: -40 to +100° C (-40 to +212°
F)
EMITTER CHARACTERISTICS (LR400): infrared LED,
880nm
CONSTRUCTION: totally encapsulated, hermetically sealed
lenses. Anodized aluminum housings with two plated steel jam nuts
(supplied). NEMA 1, 3, 4, 12, and 13.
CABLE: sensors are supplied with 6' of PVC-covered cable.
30' cables are available by special order.
