LR300 & PT300

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 field 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 flex-

ible, low-profile 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

modulated amplifiers, and MB Series amplifiers.

RANGE: up to 8 feet in opposed mode (see gain curve)

EFFECTIVE BEAM: 0.14 inch (3,6 mm) diameter

RESPONSE SPEED: a function of the amplifier (see below)

OPERATING TEMPERATURE: -40 to +80° C (-40 to +176° F)

EMITTER CHARACTERISTICS: infrared LED, 880nm

CONSTRUCTION: totally encapsulated, hermetically sealed lenses.

Valox

CABLE: sensors are supplied with 6' of low-profile 2-wire PVC-cov-

ered cable. 30' cables are available by special order.

Hookup to MB Series Amplifiers

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. 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).

OUTPUT CONFIGURATION: open collector NPN transistor; maximum

on-state current 250mA, maximum off-state leakage current 100 micro-

RESPONSE SPEED: 1 millisecond ON and OFF.

OPERATING TEMPERATURE RANGE: 0 to +50°C (+32 to +122° F).

Opposed Mode

Remote Sensor Pair

Wiring rules:

1) Avoid running remote sensor cables in wireways together with

power-carrying conductors.

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.)
