The Banner Engineering MA3 Series overview:
Banner MICRO-AMP modules MA3 and MA3P are modulated amplifiers 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 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 complementarycurrent 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 .
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.
