MULTI-BEAM®LS10 Light Screen System

For Sensing Small Parts at High Speeds

Printed in USA 05/08 P/N 03557 rev. F

*Emitters come with a 3-pin Mini-style connector; receivers come with a 4-pin connector. All require a mating cable; see page 5.

LS10 Light Screen System

• Emitter and receiver pair produce a strobed array of modulated light
beams to produce a light screen

• Simple, economical and highly reliable means of sensing small parts
which pass anywhere through the light screen

• Light screen area measures 90 mm (3.5") high, and as wide as the
distance between the emitter and receiver

• Fast, 1 millisecond response; output includes a 5-millisecond pulse
stretcher for interfacing reliability

• Tight beam spacing for sensing small parts as small as 5.6 mm (0.22")
diameter

• Totally self-contained; very rugged with totally encapsulated circuitry

• Bipolar design offers the choice of NPN (current sinking) or PNP
(current sourcing) outputs from the same receiver; both outputs may
be used simultaneously

WARNING . . .

Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety
applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current
Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

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.
