Model MA3-4P: PNP (current sourcing) output
Banner MICRO-AMP
®
module
models MA3-4
and MA3-4P are modulated ampli-
fiers designed for use with the popular family of Banner high-performance remote
sensors. When these modulated remote sensors are used with the MA3-4 or MA3-4P,
their optical response is the same as when they are used with the larger MAXI-AMP
CM Series modules.
These modules are powered by 10 to 30 volts dc. They feature the patented Banner
Alignment Indicator Device (AID™) signal strength LED. Sensor sensitivity is ad
-
justable via a top-mounted GAIN potentiometer. Circuitry is epoxy-encapsulated and
protected by a tough molded VALOX
®
housing. Connections may be made to these
modules via the optional RS8 socket/wiring base, or the module may be mounted
directly to a printed circuit board.
The sensors which are used with these modules are totally encapsulated for durability
and infinite life. Wide beam angles eliminate alignment problems, and high optical gain permits reliable sensing under severe condi
-
tions.
OUTPUT:
two PNP transistors, complementary outputs; one normally open (light operate) and one normally closed (dark operate). 150 mil
-
liamps maximum, each output. Saturation voltage less than 1V dc at 10 milliamps. Off-state leakage current less than 1 microamp.
Model MA3-4P has the same specifications and performance as the MA3-4 amplifier, except that the MA3-4P has complementary PNP outputs
in place of the MA3-4's NPN configuration.

Printed in USA
ADJUSTMENT:
GAIN adjustment (single-turn potentiometer; adjust
with small flat-blade screwdriver).
INDICATOR:
exclusive Banner Alignment Indicator Device (AID™)
system lights a red LED indicator whenever the sensor "sees" its own
modulated light source, and pulses at a rate proportional to the strength
of the received light signal.
CONSTRUCTION:
totally encapsulated plug-in package with
molded VALOX
®
housing. Gold-flashed connection pins.
OPERATING TEMPERATURE:
-40 to +70 degrees C (-40 to +158 degrees F).
