Banner MICRO-AMP Series - Manual (Page 18)

Amplifier model MPC3A is a modified version of standard model
MPC3 (pages 15-16). The MPC3A is configured for use with sensor
model SP100FF.
Model MPC3A is a miniature "component" amplifier 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.
Specifications 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 page 15 for complete information.
MICRO-AMP modulated amplifier model MA3A is designed for
use with the SP100FF sensor. Model MA3A has the same specifica-
tions as standard MICRO-AMP model MA3 (page 3), with the excep-
tions of response speed and sensor hookup.
Model MA3A offers complementary current sinking outputs. Each
output has sufficient capacity to switch small electromechanical de-
vices, 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 (see page 19).
Model MA3A features the patented Banner Alignment Indicator De-
vice (AID™) signal strength LED. The SP100FF's sensitivity is
adjustable via a gain potentiometer on top of the amplifier 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 amplifier model MA3 on page 3 of this catalog.
