WORLD-BEAM QS186LE Laser Emitter
Datasheet
Class 1 and 2 lasers for use with Banner modulated photoelectric receivers
• Self-contained Class 1 or Class 2 modulated visible laser diode emitters
permit higher gain than LEDs and extended range in opposed-mode
sensing systems.
• Narrow effective beam provides small-object detection and precise
position control.
• Bright spot and multiple shapes provide great visual marking of objects.
• 10 to 30 V dc operation; third wire extinguishes laser light when
connected to +V correct dc.

Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix "W/30" (QS18LE W/30). To
order the 4-pin Pico-style pigtail QD models, add suffix "Q" (QS18LEQ). To order the 4-pin integral Pico-style QD models,
add suffix "Q7" (QS18LEQ7). To order the 4-pin Euro-style QD pigtail models, add suffix "Q5" (QS18LEQ5). To order the 4-
pin integral Euro-style QD models, add suffix "Q8" (QS18LEQ8).
Models with a QD connector require a mating cable.
WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death.
This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.
1 Not recommended for dusty or dirty environments; the scattered light would greatly reduce excess gain.

WORLD-BEAM QS186LE Laser Emitter
Alignment
Conventional modulated infrared LED photoelectric emitters are designed with beam divergence angles of several degrees.
As a result, most emitters are easily aligned to their receivers by simple line-of-sight methods.
The beam widths listed (see
Figure 1
on page 2) are also the effective beam sizes at the receiver for model QS186LE.
The effective beam size is equal to the minimum opaque object profile required to block the laser beam. The beam size at
the emitter is 2.5 mm (0.1 inches) diameter. Beam sizes at various distances for other models are shown in the tables
below.
The effect of angular misalignment is dramatic (see
Figure 3
on page 3). The wide beam angles offered by conventional
photoelectric emitters allow several degrees of misalignment between the optical axes of the emitter and receiver. This is
not true for laser emitters, which require the beam center to directly strike the receiver lens. The figures show how far the
laser beam will miss the center of the receiver lens for one degree of angular misalignment (in any plane). Note that even
at a 5 foot range, one degree of misalignment will cause the laser beam to miss the lens of most receivers.

WORLD-BEAM QS186LE Laser Emitter
Alignment Tip:
The visible red beam of the laser emitter is easily
seen in subdued lighting. At opposed distances of up to 10 feet,
attach a sheet of white paper directly in front of the receiver lens
and mark the location of the lens center on the paper. Using the
mark as an aiming target, sight along the beam from directly
behind the laser emitter. Adjust the emitter mounting until the dot
of red light is centered exactly on the mark. Remove the paper and
check the response of the receiver.
For longer distances (up to 25 feet), replace the white paper with a
4 x 4 inch square of high-grade retroreflective tape (Banner model
BRT-THG-4X4-5 or equivalent; see
Figure 2
on page 3). For
greater distances, use a larger sheet of retroreflective material
(see
Retroreflective Tape
on page 6).
At long distances, use retroreflective tape to locate the beam at
the desired location. Never use a mirror as an alignment target.

WORLD-BEAM QS186LE Laser Emitter
Description of Laser Classes
Class 1 Lasers.
Lasers that are safe under reasonably foreseeable conditions of
operation, including the use of optical instruments for intrabeam viewing.
Reference IEC 60825-1:2001, section 8.2.
Class 1 Laser Characteristics: see specifications.
Class 2 Lasers.
Low-power lasers are by definition incapable of causing eye injury
within the duration of the blink (aversion response) of 0.25 seconds. This reaction
may be expected to provide adequate protection under reasonably foreseeable
conditions of operation, including the use of optical instruments for intrabeam
viewing. They also must emit only visible wavelengths (400–700 nm). Therefore, an
ocular hazard can exist only if an individual overcomes their natural aversion to
bright light and stares directly into the laser beam.
For safe laser use:
•
•
•
Do not permit a person to stare at the laser from within the beam.
Do not point the laser at a person’s eye at close range.
The beam emitted by a Class 2 laser product should be terminated at the
end of its useful path. Open laser beam paths should be located above or
below eye level where practical.
Pulse Power < 4 mW, 645 - 665 nm, 35 kHz,
5.1 uS Pulse. Complies TO 21 CFR 1040.10 &
EN60825-1:2001 except for deviations pursuant
to laser notice No. 50, dated 7-26-01.

CLASS 2 LASER PRODUCT
Reference IEC 60825-1:2001, section 8.2.
Class 2 Laser Characteristics: see specifications.
CAUTION: Do Not Disassemble for Repair
This device contains no user-serviceable components. Do not attempt to disassemble for repair. Use of
controls or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure. A defective unit must be returned to the manufacturer.
Installation
To mount the QS186LEx into bracket models SMB18A or SMB46A, follow these steps.
1. Insert the laser emitter into the hole in the bracket.
2. Tighten the hex jam nut to the bracket until the emitter is held securely in place.
3. Mount the bracket using user-supplied screws or bolts. The SMB18A bracket uses M4 or #8 screws or bolts and the
SMB46A bracket uses M5 or #10 screws or bolts.
4. Check the sensor alignment, see
Alignment
on page 2. If you are using the adjustable bracket (model SMB46A),
tighten or loosen one or two of the precision alignment screws, using the supplied 2 mm Allen wrench, until the laser is
accurately aligned.
