LS10 System Overview
LS10 Light Screen Systems consist of two self-contained units: an emitter and a
receiver. Multiple infrared LEDs in the emitter are aligned in a row and strobed (turned
ON one at a time) in a specific sequence and at a high frequency. Receivers contain a
matching array of phototransistors. The length (height) of the array is 90 mm (3.5"),
and produces a curtain of light as wide as the distance between the emitter and
receiver. The receiver may be placed 4" to 48" opposed from the emitter
(LS10E/LS10R) or 4" to 8" away (LS10ESR/LS10RSR). The LS10E/LS10R system can
detect objects as small as 7.6 mm (0.30") in diameter; minimum detectable object
profile for the LS10ESR/LS10RSR system is 5.6 mm (0.22").
NOTE: Sensing should not take place within 1/2" of any LS10 system sensor face.
The light from the emitter is modulated to minimize sensitivity to ambient light. An
indicator LED on the emitter lights whenever power is applied. The receiver has an
Alignment LED which lights whenever the beam is broken.
The receiver output interfaces directly with dc loads or circuits up to 30V dc, and
offers both sinking (NPN) and sourcing (PNP) output transistors. The sinking (NPN)
output may be connected directly to any Banner MAXI-AMP or MICRO-AMP logic
module for additional system control. Outputs are energized continuously while the
beam is broken. A 5 millisecond pulse stretcher (OFF delay) is included to improve
interfacing reliability.
