MICRO-AMP® System
MA3 and MA3P Modulated Amplifiers
BannerMICRO-AMP®modulesMA3andMA3Paremodulatedamplifiers designed
for use with the miniature SP100 Series remote sensors. Miniature photoelectric
sensors,suchastheSP100s,havetraditionallybeenusedasnon-modulateddeviceswith
very limited response. These specially-engineered amplifiers 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.

Model MA3P: PNP (current sourcing) output
Model MA3P has the same specifications and performance as the MA3 amplifier, except that the MA3P has complementary PNP outputs in
place of the MA3's NPN configuration.
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.

MICRO-AMP® System Accessories
RS8 Socket
The RS8 socket is the most fre-
quently used means of mount-
ing and wiring a MICRO-AMP
module. It consists of a socket
with two four-terminal connec-
tion strips, all wired together
onto a PC board. The PC board
assembly slides into a 1 inch
(25mm) long PVC track which
is used to mount the entire as-
sembly. A hold-down screw
keys the correct polarity of the
module.

Wiring Socket
RS8K Socket
The RS8K is a kit of parts that
comprise the socket portion of
the RS8 assembly. It is used to
provide a socket for MICRO-
AMP modules that are installed
onto printed circuit boards. The
RS8K consists of a molded
socket block and 8 individual
socket pins. A nylon screw is
includedtoaffixthesocketblock

PVC mounting track for MICRO-AMP components is available in 6 and 12 inch
lengths for systems which use multiple components. For example, a 6-inch length
will accomodate one MPS-15 power supply plus two additional RS8 sockets with
modules.
Longer lengths of mounting track may be supplied on a quote basis.

MPS-15 and MPS-15-230 Power Supplies
The MPS-15 Series power supplies are designed specifically to supply power for the
Banner MICRO-AMP series amplifiers and logic modules. They are constructed on small
PC boards that are track-mountable for compatibility with other track-mounted MICRO-
AMP components. The MPS-15 includes a socket for a MICRO-AMP amplifier or logic
module having current sinking (NPN) output*. The combination of an MPS-15 series
power supply and a MICRO-AMP module makes a complete and compact sensing and/or
control system.
A built-in 5-amp rated SPDT output relay is supplied for easy interfacing to an external
load or circuit. Its action is controlled by the outputs of a MICRO-AMP module which is
plugged into the on-board module socket*. Aswitch on the PC board selects which module
output (normally open or normally closed) will activate the relay.
Two models are available. Model MPS-15 is for 120V ac operation. Model MPS-15-230
is for 220/240V ac power. Up to three MICRO-AMP modules may be powered by one
MPS -15 or MPS-15-230 power supply. A 4-inch (10cm) long mounting track is included
with each supply. Optional 6-inch (15cm) track model TR100-6 neatly accomodates the
MPS-15 Series PC board plus the PC boards of two additional RS8 sockets to form a
complete three-module MICRO-AMP sensing/logic system. (See Mounting Track infor-
mation, page 3.)
*Do not plug MICRO-AMP modules with PNP (current sourcing) outputs ("P" suffix) into the socket on the MPS-15 or MPS 15-230 power supply.
