SUPPLY VOLTAGE: 10 to 30V dc at less than 20 milliamps (ex-
clusive of load); 10% maximum ripple.
OUTPUT CONFIGURATION: two open-collector NPN (current
sinking) transistor (solid-state) switches; one normally open (light
operate) and one normally closed (dark operate); 150 milliamps maxi-
mum, each output. Saturation voltage less than 0.5V dc at 10 milliamp
load. Off-state leakage current less than 1 microamp.
RESPONSE SPEED: 1 millisecond ON and OFF.
REPEATABILITY: 0.3 millisecond.
SENSOR LEAD LENGTH: 15 feet (4,5 m) maximum.
ADJUSTMENT: GAIN adjustment (single-turn potentiometer;
adjust with small at-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-ashed connection pins.
OPERATING TEMPERATURE:
0 to +70 degrees C (32 to +158 degrees F).

Model MA3 Specications
Model MA3P has the same specications and performance as the MA3 amplier, except that the MA3P has complementary PNP outputs in
place of the MA3's NPN conguration.
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 is less than 1V dc at 10 milliamps. Off-state leakage current is less than 1 microamp.

modules MA3 and MA3P are modulated ampliers designed
for use with the miniature SP100 Series remote sensors. Miniature photoelectric
sensors, such as the SP100s, have traditionally been used as non-modulated devices with
very limited response. These specially-engineered ampliers bring about a dramatic
improvement in the optical performance of miniature remote sensors.
MICRO-AMP modules are powered by 10 to 30 volts dc, and feature the patented
Banner Alignment Indicator Device (AID™) signal strength LED. Sensor sensitivity
is adjustable via a top-mounted GAIN potentiometer. Model MA3 has complemen-
tary current sinking (NPN) outputs; model MA3P has complementary current sourc-
ing (PNP) outputs. Circuitry is epoxy-encapsulated and enclosed in a tough molded
VALOX
®
housing. Connections may be made to the MICRO-AMP via the optional
RS8 socket/wiring base, or the module may be mounted directly to a printed circuit
board (see page 3).
The small size and the slim ribbon-style connecting cable of SP100 Series sensors
make it possible to use photoelectrics in many situations previously thought to be
impractical or even impossible.
