Quick Start Guide
Laser displacement sensor with dual discrete (switched) outputs
This guide is designed to help you set up and install the L-GAGE®LE Laser Gauging Sensor. For complete information on
programming, performance, troubleshooting, dimensions, and accessories, please refer to the Instruction Manual at
www.bannerengineering.com. Search for p/n 185600 to view the manual. Use of this document assumes familiarity with
pertinent industry standards and practices.
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.

Laser Description and Safety Information
CAUTION: Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure. Do not attempt to disassemble this sensor for
repair. A defective unit must be returned to the manufacturer.
Class 2 Laser Models
CAUTION: Never stare directly into the sensor lens. Laser light can damage your eyes. Avoid
placing any mirror-like object in the beam. Never use a mirror as a retroreflective target.
For Safe Laser Use - Class 2 Lasers
•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.

Class 2 Lasers
Class 2 lasers are lasers that emit visible radiation in the wavelength range from 400
nm to 700 nm, where eye protection is normally afforded by aversion responses,
including the blink reflex. This reaction may be expected to provide adequate
protection under reasonably foreseeable conditions of operation, including the use of
optical instruments for intrabeam viewing.
Figure 2. FDA (CDRH) warning label
(Class 2)
Class 2 Laser Safety Notes
Low-power lasers are, by definition, incapable of causing eye injury within the
duration of a blink (aversion response) of 0.25 seconds. They also must emit only
visible wavelengths (400 to 700 nm). Therefore, an ocular hazard may exist only if
individuals overcome their natural aversion to bright light and stare directly into the
laser beam.
Class 1 Laser Models
Class 1 lasers are lasers that are safe under reasonably foreseeable conditions of
operation, including the use of optical instruments for intrabeam viewing.

Sensor Installation
NOTE: Handle the sensor with care during installation and operation. Sensor windows soiled by
fingerprints, dust, water, oil, etc. may create stray light that may degrade the peak performance of the
sensor. Blow the window clear using filtered, compressed air, then clean as necessary using 70%
isopropyl alcohol and cotton swabs or water and a soft cloth.
Sensor Orientation
Correct sensor-to-object orientation is important to ensure proper sensing. See the following figures for examples of
correct and incorrect sensor-to-object orientation as certain placements may pose problems for sensing distances.

Sensor Mounting
1. If a bracket is needed, mount the sensor onto the bracket.
2. Mount the sensor (or the sensor and the bracket) to the machine or equipment at the desired location. Do not
tighten at this time.
3. Check the sensor alignment.
4. Tighten the screws to secure the sensor (or the sensor and the bracket) in the aligned position.
