Banner Maxi-Beam sensors are highly versatile, self-contained, modularized photoelectric sensing controls that are ideally suited to industrial environments. The basic MAXI-BEAM is an ON/OFF switch consisting of three modules (sensor head, power block, and wiring base) and a unique, patented, rotatable "programming ring" that enables you to program your choice of "light" or "dark" operate modfe, sensing range, and response time.

MAXI-BEAM sensor heads have an easily-accessible multi-turn SENSITIVTITY control for precise adjustment of system gain. Interchangeable sensor heads are rotatable in 90-degree increments and are available in retroreflective, diffuse, opposed, convergent, and fiberoptioc sesning modes. Each sensor head also includes Banners AID circuit (Alignment Indicating Device), which features an LED alignment indicator that lights whenever the sensor "sees" its own modulated light source, and pulses at a rate proportional to the strength of the received light signal.
