Instruction Manual

MICRO-AMP modulated amplier model MA3A is designed for use
with the SP100FF sensor. Model MA3A has the same specications as
standard MICRO-AMP model MA3, with the exceptions of response
speed and sensor hookup.
Model MA3A offers complementary current sinking outputs. Each
output has sufcient capacity to switch small electromechanical devices,
such as relays, and will directly interface logic inputs.
Connections are made using the optional RS8 socket and wiring base,
or the MA3A may be mounted directly to a PC board. The sensing
system is powered by +10 to 30V dc. Power supply model MPS-15 is
available, and includes its own board-mounted socket for the MA3A
and a built-in SPDT output relay.
Model MA3A features the patented Banner Alignment Indicator Device
(AID™) signal strength indicator system*. The SP100FF's sensitivity
is adjustable via a gain potentiometer on top of the amplier module.
Circuitry is epoxy-encapsulated and protected by a tough molded
VALOX
®
housing.
Additional information for model MA3A may be obtained from the
description of standard amplier model MA3 in Banner product data
sheet P/N 03340.

Specications, model SP100FF
Amplier model MPC3A is a modied version of standard model
MPC3 (product data sheet P/N 03336). The MPC3A is congured for
use with sensor model SP100FF.
Model MPC3A is a miniature "component" amplier that is designed
for mounting directly to a PC board. The MPC3A is powered by +5V
dc, and outputs are conventional buffered (complementary) CMOS
gates.
Specications for model MPC3A (except for response time and hookup
information) are identical to standard model MPC3. MPC3A response
time is less than 1.5 milliseconds, and may be adjusted for faster response.
See Banner product data sheet P/N 03336 for complete information.
Power Supply Requirements: +10 to 30V dc at less than 20mA;
10% maximum ripple. Power may be obtained from Banner power
supply model MPS-15, CP12C, CP12RC, or PS120-15.
Output Conguration: two open-collector NPN (current sinking)
transistor solid-state switches, one normally open, one normally closed.
150mA maximum, each output.
Response speed: 2 milliseconds (typical)
Maximum Sensor Lead Length: 15 feet (4,5 m)
Operating Temperature: 0 to 70°C (+32 to 158°F)
