Remote Sensor Pair

Specications, 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 sen-

sor 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. Chassis models with additional octal sockets are also avail-

able. Other types of output devices, including solid state relays, may be

ordered (see Banner catalog).

Hookup to MB Series Ampliers

The LR250 emitter and PT250 receiver are compact, totally-encapsulated opposed mode remote sensors whose 1/4" diameter smooth

barrel design and excellent operating characteristics make them ideal for many sensing applications. Mounting and alignment are

extremely simple, due to these sensors' wide eld of view. The LR250 and PT250 may be mounted through a 1/4" (6,4mm) clearance

hole and held in place by a setscrew, or in a model SMB250 mounting block.

LR/PT250 series sensors are fully encapsulated, and have hermetically sealed lenses to eliminate internal condensation. Units may

be washed down without damage. Identical optical performance in different housing styles is available in models LR/PT200, 300, and

400 (see Banner product catalog).

The minimum object size required to break the beam of the LR250/PT250 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.

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 amplier.

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.)

sees "light") or dark-operated AND logic (input to module occurs when

all receivers simultaneously see "dark") is possible.

CM Series modules combine power supply, modulated photoelectric

amplier, 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. See

the Banner product catalog for further in formation.

Up to three sensor pairs may be connected to each amplier. Light- op-

erated OR logic (input to module occurs whenever at least one receiver

NOTE: to power the MAXI-AMP from a DC power supply, connect

+12 to 18V dc at ≥70mA to terminal #3 and DC common to terminal

#1. Make no connections to terminal #7 or #8.

Hookup to MAXI-AMP™ CM Series Modules

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 sensors with extended cable length.

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

Specications, MAXI-AMP CM Series Modules

WARNING These photoelectric presence sensors and ampliers do NOT include the self-checking redundant circuitry neces-

sary to allow their use in personnel safety applications. A sensor or amplier 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.

Specications, MICRO-AMP MA3-4 and MA3-4P

POWER SUPPLY REQUIREMENT: 10-30V dc at less than 20mA; 10% maximum

ripple (obtainable from MPS-15 power supply--see above).

OUTPUT CONFIGURATION: model MA3-4 has two open-collector NPN (cur-

rent sinking) transistor solid state switches, one normally open, one normally closed.

150mA max. each output. Model MA3-4P has two PNP (sourcing) outputs, 150mA

max. each.

RESPONSE SPEED: 1 millisecond ON and OFF.

MAXIMUM SENSOR LEAD LENGTH: 30' (9m).

OPERATING TEMPERATURE RANGE:

-40 to +70 degrees C (-40 to +158 degrees F).

Hookup to MICRO-AMP® Modules

MICRO-AMP amplier 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 the 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/PT250s may be connected to each ampli-

er.

When wiring two sensors to one

MAXI-AMP, multiply excess gain

data (from excess gain curve) for

each sensor by 1/2; when wiring

three sensors to one MAXI-AMP,

multiply excess gain by 1/3.
