LS4EL/RL Light Screen Systems offer a simple, economical, but highly

reliable means of sensing objects moving at high speed through an area (or

"window"). Each system consists of two self-contained units: an emitter and

a receiver. Emitters contain four infrared light sources 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

height of the array is 3.5 inches (90 mm). The LS4RL receiver may be placed

18 to 90 inches (45,7 to 228,6 cm) opposed from the LS4EL emitter. This

produces a "curtain" of light 5 to 6 inches high and as wide as the separation

distance between the emitter and receiver.

The smallest object that can be detected depends upon the location of the

object within the curtain. Midway between emitter and receiver, an object 1

inch (25 mm) or larger in cross section can be detected anywhere within a 5

inch (127 mm) high window. Near the emitter or receiver, an object of 1.5

inches (38 mm) or larger in cross section can be detected anywhere within a

6 inch (152 mm) high window.

The light from the emitter is modulated to minimize sensitivity of the system

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. Models are available with either attached cable or integral quick

disconnect (QD) fitting. The receiver output interfaces directly with dc loads

or circuits up to 30V dc, and offers both sinking (NPN) and sourcing (PNP)

output transistors. Outputs are energized continuously while the beam is

broken. A 5 millisecond pulse stretcher (OFF delay) is included to improve

interfacing reliability.

Functional Schematic, LS4 Light Screen Systems

Quick disconnect model emitter and receiver both use Banner mini-type mating

cable model MBCC-412 (p/n 25226, length 12 feet). Model MBCC-430 is also

available (p/n 29951, length 30 feet). Order cable separately.

Pin #1 (Black): sourcing output (receiver only)

Pin #2 (Blue): common (dc neg.) (emitter and receiver)

Pin #3 (Brown): +10 to 30V dc (emitter and receiver)

Pin #4 (White): sinking output (receiver only)

NOTE: Emitters have no connection to pins #1 and #4.
