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.

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.
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.
LASER LIGHT - DO NOT STARE INTO BEAM
CLASS 2 LASER PRODUCT
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.
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 3. 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.

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 3) 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 4). 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.
Receiver
Target
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 BRTTHG-4X4-5 or equivalent; see Figure 2 on page 4). For greater
distances, use a larger sheet of retroreflective material (see
Retroreflective Tape on page 6).
Laser Emitter
At long distances, use retroreflective tape to locate the beam at the
desired location. Never use a mirror as an alignment target.
