Product Overview

The MA3-4 is a MICRO-AMP® Modulated Amplifier designed for use with the popular family of Banner high-performance remote sensors. When this modulated remote sensor is used with the MA3-4, their optical response is the same as when they are used with the larger MAXI-AMP CM series modules. This module is powered by 10 to 30VDC. It features the patented Banner Alignment Indicator Device (AID™) signal strength LED. Sensor sensitivity is adjustable via a top-mounted GAIN potentiometer. Circuitry is epoxy-encapsulated and protected by a tough moulded VALOX® housing. Connections may be made to these modules via the optional RS8 socket/wiring base or the module may be mounted directly to a printed circuit board. The sensors which are used with these modules are totally encapsulated for durability and infinite life. Wide beam angles eliminate alignment problems and high optical gain permits reliable sensing under severe conditions.

  • 10 to 30VDC at <20mA Supply voltage
  • 1ms ON and OFF Response speed
  • 0.3ms Repeatability
  • 30ft (9m) Maximum sensor lead length
