| Scanner blocks for opposed, retro, diffuse, convergent, and fiber optic sensing modes; Most scanner blocks include Banner's exclusive, patented 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; 0.6 IN diameter visible red spot, for precise positioning, edge-guiding, and small parts detection; Sensor-to-product distance must be consistent; Some products may be sensed against immediate background like parts on a conveyor; Excellent for high-contrast registration-sensing applications; 3 and 4 wire system |
