| Scanner blocks for opposed, retro, diffuse, convergent, and fiber optic sensing modes; 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; SBDL1 - longer range than SBD1, but with less response to objects passing the sensor at close range, and greater sensitivity to background objects; Models SBD1 and SBDL1 are identical except for their upper cover (lens) assembly (SBD1 uses UC-D; SBDL1 uses UC-L); 3 and 4 wire system; Interconnecting pins |
