Cut Sheet

MODEL QS30LLPC(Q) is configured using the Low-Contrast SET procedure. It is useful for small object detection and
other applications with small variations in contrast, such as yarn- or thread-break applications. See Low-Contrast SET -
Model QS30LLPC on page 5 for more information.

Description of Laser Classes
Class 1 Lasers
Class 1 lasers are 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.
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.
For Safe Laser Use (Class 1 or Class 2):
• Do not stare at the laser.
• Do not point the laser at a person’s eye.
• Mount open laser beam paths either above or below eye level, where practical.
• Terminate the beam emitted by the laser product at the end of its useful path.
Device Setup
Installation Notes
Conventional retroreflective photoelectric sensors are extremely easy to align. Beam angles are wide, and retro targets are
forgiving to the light beam’s angle of incidence. The beam of this laser sensor is very narrow, compared with the beam of
most retro sensors. As Figure 6 indicates, the effect of angular misalignment can be dramatic. Alignment is critical because
the beam may miss the retroreflective target unless the target is large.
