MA3

The MA3 is a Modulated Amplifier designed for use with SP100 series miniature remote sensors. Miniature photoelectric sensor has traditionally been used as non-modulated devices with very limited response. MICRO-AMP amplifier has a specially-engineered modulated design which brings about a dramatic improvement in the optical performance of miniature remote sensors. MICRO-AMP module is powered by 10 to 30V DC and feature the patented Banner Alignment Indicator Device (AID™) signal strength LED. Sensor sensitivity is adjustable via a top-mounted GAIN potentiometer. The sensor features two open-collector NPN (current sinking) transistor (solid-state) switches, one normally open(light operate) and one normally close(dark operate) output configuration. Circuitry is epoxy-encapsulated and enclosed in a tough moulded 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 (page 20).
