MICRO-AMP® System

MA3 and MA3P Modulated Ampliers

Banner MICRO-AMP® 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 complemen­tary current sinking (NPN) outputs; model MA3P has complementary current sourc­ing (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.

MICRO-AMP® Model MA3 Specications

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 maxi­mum, 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 MA3P: PNP (current sourcing) output

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 mil­liamps maximum, each output. Saturation voltage is less than 1V dc at 10 milliamps. Off-state leakage current is less than 1 microamp.

SP100DB

OPPOSED Mode Sensors

SP100E and SP100R miniature opposed sensors have a slim right-angle design

which allows them to be mounted in very tight locations. The thin, exible rib­bon cable which exits from one corner may be run in any direction away from
the sensing point. The SP100E and R have a wide beam angle for forgiving

line-of-sight alignment. Alignment is easily made exact (and monitored) using
the AID™ LED on the MICRO-AMP module.

DIFFUSE Mode Sensors

Models SP100D and SP100DB are general-purpose miniature diffuse sensors

which detect the reection of their own light from the surface of an object. The

SP100D is a right-angle design which is generally held in place using a #4 (3mm)

screw. The SP100DB ("B" = Barrel) is an in-line threaded barrel which typically

mounts through a 3/8" (10mm) diameter hole using the lock nuts which are sup­plied. The optical response characteristics of these two sensors are identical.

CONVERGENT Mode Sensors

SP100C SP100CCF

Models SP100C and CCF are ideally suited to applications where depth of eld
is critical. The emitter and receiver are both directed at a point 0.1 inch (2,5mm)

ahead of the front surface. An aperture is included which, when attached, nar-

rows the depth of eld (see curves, below). This is particularly useful when it
is necessary to detect an object while ignoring another object or a surface just a

fraction of an inch farther away. The high excess gain at the focus allows detec-

tion of objects of low reectivity. The SP100C and CCF differ only in housing

style. Model SP100C is for general application. Model SP100CCF is used where

a narrow prole is important for mounting.

MICRO-AMP® System Accessories

RS8 Socket

The RS8 socket is the most fre­quently used means of mount­ing and wiring a MICRO-AMP
module. It consists of a socket
with two four-terminal connec­tion 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.

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 MICRO­AMP 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

included to afx the socket block
to the PC board. The drill size for

the pins is #50 (.070"; 1,8mm).
Drill pattern dimensions are
included.

MPS-15 and MPS-15-230 Power Supplies

The MPS-15 Series power supplies are designed specically to supply power for the

Banner MICRO-AMP series ampliers and logic modules. They are constructed on small
PC boards that are track-mountable for compatibility with other track-mounted MICRO­AMP components. The MPS-15 includes a socket for a MICRO-AMP amplier 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*. A switch 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 infor­mation, page 3.)

*Do not plug MICRO-AMP modules with PNP (current sourcing) outputs ("P" sufx) into the socket on the MPS-15 or MPS 15-230 power supply.
