L-GAGE®LH Series Sensor

1 Introducon
Banner's LH Series Laser Displacement Sensor brings a sophiscated and cost-eecve soluon to precision measurement applicaons.
Featuring a narrow eecve beam, excellent resoluon, and user congurable outputs, the LH Series sensor solves a variety of
measurement applicaons with an all-in-one design. The LH Series Sensor can serve as a displacement measurement sensor or can
perform thickness delta measurements when two sensors are congured to work together. The LH Series Congurator is a soware tool
for seng up a network of sensors, conguring sensors, and acquiring measurements using serial communicaon over RS-485.
Measurements from mulple sensors can be simultaneously acquired using the LH Network protocol.
This instrucon manual provides an overview of the LH Series Laser Displacement
Sensor and describes how to install and prepare for conguring the sensor.
Features
• Provides precise displacement measurements or thickness delta
measurements (thickness delta measurements requires two sensors)
• Self-contained Class 2 modulated visible laser gauging sensor
• Needs no separate controller
• Narrow eecve beam is excellent for precision gauging applicaons
•Automac run mode dynamically adjusts laser power and measurement
rate based on target condions or measurement rate can be locked by user
• 4-20 mA analog output that can be easily scaled over a specied
measurement window
• Digital output provides the measurement value on the RS-485 bus
• Sensor can be easily congured using LH Series Congurator soware
Components
Each LH Series Laser Displacement Sensor Kit includes the following:
• 1 LH Series High-Performance Laser Displacement Sensor
• 1 CD containing Banner LH Series Congurator (p/n 13597) and LH Series Laser Displacement Sensor Congurator Soware
Manual (p/n 150307)
• This Installaon Guide (p/n 152154)
Note: A INTUSB485-LH converter to connect the LH Series Sensor to a PC can be purchased separately.
WARNING: Not To Be Used for Personnel Protecon
Never use this device as a sensing device for personnel protecon. 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
applicaons. A sensor failure or malfuncon can cause either an energized or de-energized sensor output
condion.
WARNING: Class 2 Safety Notes
Low-power lasers are by denion incapable of causing eye injury within
the duraon of the blink, or aversion response of 0.25 seconds. They
must also emit only visible wavelengths (400-700 nm). Therefore, an
ocular hazard can only exist if an individual overcomes their natural
aversion to bright light and stares directly into the laser beam. The device
requirements for these lasers are to have a [hazard] label and to have an
indicator light to indicate laser emission.
The two operaonal safety rules are:
• 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
WARNING: Beam Paths:
The beam emied 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 praccal.

* The shield/drain wire is connected internally to the sensor housing and should be connected as follows:
1. If the sensor housing is mounted so that it is in connuity with both the machine frame and earth ground, connect the shield/
drain wire (also) to earth ground.
2. If the sensor housing is mounted so that it is insulated from the machine frame, connect the shield/drain wire to -V dc (together
with the blue wire).
3. If the sensor is mounted so that it is in connuity with the machine frame, but not with earth ground, do not connect the
shield/drain wire (i.e. cut o the shield/drain wire).
2.2 Installaon
The LH Series Laser Displacement Sensor is an opcal instrument capable of micrometer-level resoluons.
Note: Handle the sensor with care when installing and operang. Applicaons requiring measurement resoluon in the
micrometer range must take vibraon, dust, and thermal expansion eects into consideraon. Windows of all sensors must be
clean for full funconality. Windows that are soiled by dust, water, oil, etc may cause the sensor to not operate correctly. The
windows should be cleaned thoroughly whenever necessary, using a high quality glass cleaner.
2.2.1 Displacement Measurement Installaon
1. Adjust the distance between the sensor head and the target so the target is near the middle of the measurement range.
2. The sensor must be aligned to the target so the laser beam strikes the target surface at a right angle.
3. Secure the sensor with 3 bolts of 4 mm diameter.
4. Aach the M12 cord set and complete wiring of the sensor.

Target moon must be perpendicular to emier/receiver axis.
Some targets (those with a stepped plane facing the sensor, a boundary line, or rounded targets) pose specic problems for sensing

2.2.2 Thickness Delta Measurement Installaon
For thickness delta measurement using two sensors, the "master/slave separaon" is signicant instead of the "middle of range" that is
signicant when measuring displacement. It is frequently necessary to measure materials whose thickness lies in a parcular range. In
such cases you should increase the distance apart by the nominal thickness of the material that is being measured.
The factory defaults for a thickness delta measurement are as follows:
Model Default Nominal Thickness Ideal Master/Slave Separaon
LH30 5 mm 65 mm
LH80 20 mm 180 mm
L-GAGE®LH Series Sensor
www.bannerengineering.com - Tel: [phone]

Model Default Nominal Thickness Ideal Master/Slave Separaon
LH150 50 mm 350 mm
The ideal master/slave separaon can be calculated by the following formula:
Ideal Separaon = 2 * Reference Distance + Nominal Thickness
For example: LH30 with 14mm nominal thickness would be calculated as follows: Ideal Separaon = 2 * 30 + 14 = 74 mm
(see Performance Specicaons for Reference Distance)
If the ideal master/slave separaon cannot be achieved due to applicaon restricons, the thickness delta measurement can sll be
congured to work properly by adjusng the Thickness Delta Oset parameter via the Banner LH Series Congurator soware.
Thickness Delta Measurement Installaon Steps:
1. Adjust the separaon distance between the Master and Slave sensors as required by the applicaon.
2. The Master and Slave sensors must be aligned to the target so the laser beam strikes the target surface at a right angle.
3. Secure both sensors with 3 bolts of 4 mm diameter.
4. Aach the M12 cord set and complete wiring of both sensors.

2.3 Handling and Storage
The LH Series Laser Displacement Sensor is an opcal instrument capable of micometer-level resoluons.
CAUTION: The sensors are delivered in shock-resistant packaging. Always handle/transport the sensors carefully to avoid rough
handling. The sensors must be stored in a dry place and should not be subjected to extreme temperature uctuaons.
