ATTENTION, LASER RADIATION – CLASS 2 LASER PRODUCT
Do not stare into beam!
The device satisfies the requirements of IEC 60825-1:2014 safety regulations for a product of
laser class 2 as well as the U.S. 21 CFR 1040.10 regulations with deviations corresponding to
"Laser Notice No. 56" from May 8, 2019.
Never look directly into the laser beam or in the direction of reflected laser beams!
If you look into the beam path over a longer time period, there is a risk of injury to the retina.
Caution: Opening the device can lead to dangerous exposure to radiation
Do not point the laser beam of the device at persons!
Interrupt the laser beam using a non-transparent, non-reflective object if the laser beam is
accidentally directed towards a person.
When mounting and aligning the device, avoid reflections of the laser beam off reflective
surfaces!

For information on technical data and characteristics, refer to Chapter 4.
3.1 Device construction of the BPS 37
Figure 3.1: Device construction of the BPS 37
3.2 Application
Wherever systems are moved automatically, it is necessary to uniquely determine their respective posi-
tions. This is achieved using various measurement procedures. In addition to mechanical measurement
sensors, optical methods are particularly well suited for determining positions as they operate without
mechanical wear and slippage.
Unlike other optical measurement methods, the bar code positioning system is not restricted to linear
movements. It can also be used flexibly in curved systems. Anywhere the long-wearing bar code tape can
be attached, it is possible to use the BPS to determine the position to within a millimeter.
Guide tolerances of the system play no roll as the permitted distance range between tape and BPS allows
for large deviations in distance.
3.3 Function
The BPS uses visible red laser light to determine its position relative to the bar code tape. This essentially
takes place in three steps:
1. Reading a code on the bar code tape
2. Determining the position of the read code in the scanning area of the laser beam
3. Calculating the position to within a millimeter using the code information and code position
The position value is then passed on via the standardized SSI interface (synchronous serial interface) to
the drive system of the vehicle for which the position is to be determined.
3.4 Advantages
• Easy mounting and commissioning
• Teach function for the "zero point", i.e. it is not necessary to exactly affix the bar code tape.
• Data output via SSI interface; BPS can be connected instead of a conventional rotary encoder.
• The function of the BPS makes it possible to attach the bar code tape only at those locations where
it is necessary that the position be known exactly.
• Positioning of non-linear movements as well
• No referencing necessary following a voltage drop
• Thanks to the large scanning depth, it is possible to compensate for mechanical tolerances.
• It is possible to exactly determine positions from distances of 10000 meters

3.5 Stand-alone operation
The bar code positioning system BPS 37 is operated as individual "stand alone" device. The BPS features
a 15-pin sub-D connector for the electrical connection of the supply voltage, the interface and the switching
inputs.
With connection units
The connection units simplify the electrical installation of the bar code positioning systems in stand-alone
operation.
Moreover, they store the operating parameters so that the configuration data are retained even if the BPS
is replaced and can show parameters and operating data on a display (MA 4D.7).
A listing of the available connection units and associated short descriptions can be found in Chapter 5.
Separate data sheets are available that contain further details about the connection units.
With MS 37 103 connector hood
The modular connector hood MS 37 103 is intended for the easy connection of the BPS 37 with M12
connection technology.

5.1.1 Connection units / connector hood
MA 4.7/MA 4D.7 connection unit
The connection units MA 4.7/MA 4D.7 are used to simplify the electrical installation of the BPS 37. They
have the following advantages compared to the installation of the BPS 37 as a stand-alone device:
• Terminals for switching inputs and outputs, including voltage supply
• 9-pin sub-D plug for service interface
• Operating mode switch: service operation/normal operation
• Code types - changeover switches binary/gray
• Rotary switch for setting the resolution
• Parameter memory for the BPS - the BPS can be exchanged without the need for reconfiguration.
• Display (MA 4D.7 only)
NOTE
Products from Leuze electronic GmbH & Co KG can be ordered from any of the sales and
service offices listed on the back page of this operating manual.

6.2 Mounting
Accessories
The mounting system BT 56 is available for installation. It may be ordered separately from Leuze elec-
tronic. For order numbers, see Table 5.1 "Accessories/order codes" on page 14.
Mounting the BPS 37
There are two basic types of mounting arrangements for the BPS 37:
• Using the dovetail groove and the corresponding mounting accessories see figure 6.1
• Using the mounting threads on the rear and bottom of the device (Chapter 4.3)
ATTENTION!
Package the device for transport and storage in such a way that is protected against shock and
humidity. Optimum protection is achieved when using the original packaging. Ensure
compliance with the approved environmental conditions listed in the specifications.
ATTENTION!
Do not use aggressive cleaning agents such as thinner or acetone for cleaning the device and
bar code tape.

Mounting of MA
You can mount all connection units individually through the holes located on the mounting plate (see
Figure 5.1).
Subsequently, connect the BPS 37 with the connection unit via the respective cable (see Chapter 5.1.3).
6.2.1 Device arrangement
Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• The scanning range determined from the scanning curve must be adhered to at all areas at which a
position determination is to be made
• The BPS should be mounted inclined by 10° in the vertical axis towards the bar code tape to ensure
that the read results are reliably obtained even if the bar code tape is soiled.
BT 56 mounting
device
NOTE
The best functionality is obtained when:
• The BPS is guided parallel to the tape
• The permitted working range is not exited
NOTE
On the BPS 37, the beam is not emitted perpendicular to the housing cover, but with an angle
of 10° towards the top. This angle is intended to prevent total reflection on the bar code tape.
