over 5,000 sensor configurations possible
Scanner blocks for opposed, retro, diffuse, convergent, and
fiber optic sensing modes (including high-gain models)
Power blocks for ac or dc operation, including 2-wire ac
operation
Logic modules to support a wide variety of delay, pulse, limit,
and rate sensing logic functions
Most scanner blocks include Banner's exclusive, patented
AID™ (Alignment Indicating Device) system, which lights a
top-mounted indicator LED whenever the sensor sees its
own modulated light source, and pulses the LED at a rate
proportional to the strength of the received light signal.
