LX Series Part-Sensing Light Screen

For Sensing Small or Flat Parts at High Speeds

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.

† Sizes not listed available on request; contact factory

* Integral cable models are listed; for 5-pin Euro-style 150 mm (6") QD pigtail, add sufﬁx “Q” to model number (e.g., LX3EQ). QD models require a mating cable; see page 4.

Features

• Emitter and receiver pair produce a strobed web of modulated light

beams, in 8 lengths, 2 sensing ranges

• Simple, economical and highly reliable means of sensing small parts or

flat items which pass anywhere through the light screen

• Fast response, output includes a 5-millisecond pulse stretcher for

interfacing reliability

• Simple wiring configuration; emitter and receiver do not need a

synchronization wire

• Rugged, self-contained and compact construction; rated IEC IP65

• Bipolar design offers both NPN (current sinking) and PNP (current

sourcing) solid-state outputs

LX Series Part-Sensing Light Screens Theory of Operation Sensing is most effective in the center 80% of the sensing range The LX Series light screen sensing system consists of two self-contained units: an emitter and a receiver of equal size and sensing range. The emitter has multiple infrared LEDs spaced at 9.5 mm (0.38") increments, and the receiver has corresponding photodiodes. The emitter sequentially fires each infrared LED.
