Shut-off clutch
proven for industry.
Our shut-off clutch is designed to minimize user influence on the fastening process. Bosch clutches
are among the most repeatable and accurate in the world. Our repeatability rivals that of some DC
smart tools costing thousands more than our EXACT cordless tools.
Precise, accurate shut-off
The EXACT clutch ensures high torque repeatability and
accuracy. Whether in a hard joint application of 30 degrees
or a soft joint of 720 degrees, the clutch guarantees an
extremely low mean value offset and consistent torque.
Clutch quality conforms to ISO 5393 requirements.
User-friendly features
The EXACT clutch provides 15% greater torque in reverse
for loosening fasteners, when needed. Specified torque
is always reached regardless of battery voltage; the
microprocessor prevents the tool from running if the
battery falls below a minimum threshold voltage.
A special tool adjusts the clutch; storing the adjusting
tool away from the end user prevents changing of torque
settings. Various snap-in color rings attach to the nose
of the tool to allow users to quickly identify various
torque range settings at the assembly line.
Precise and stable under load
Bosch quality testing for the EXACT family is extremely
rigorous. Each version of EXACT must survive a 500,000
cycle test under load without failure or excessive
adjustment before being released for production.
Standard operational life must exceed 500,000 cycles
while maintaining a minimum ISO 5393 standard CMK
value greater than 1.67 with a tolerance of ± 10% in a
range of 0.6 to 30 Newton-meters.
A proven performer
The shut-off clutch used in the EXACT cordless family
is the identical clutch used in our line of production
air tools. This clutch has been used in hundreds of
applications over the years and is a proven performer
at many of our customers’ facilities.

Error-proofing for cordless
assembly tools:
Build it better with Bluetooth EXACT.
The Bluetooth EXACT Cordless Screwdriving system thinks for itself. The BT-EXACT tool takes its
commands from the EXAConnecT controller, which stores the work in progress in real time. The
system can talk to and take commands from external devices like a PLC, bar code scanner or host
network if desired. Improve your assembly process and never miss another fastener.
Wireless OK/NOK (joint ok or not ok) signals are sent
from the BT-EXACT Screwdriver to the EXAConnecT
controller, which also sends commands back to the tool.
A class 2 Bluetooth module guarantees data transfer
without compromise using 56-bit encryption and level 3
security in Bluetooth standard 1.2. The tools and controller
communicate only with each other. The software can be
configured to actively block Bosch Bluetooth signals from
disturbing a wireless LAN, preventing data loss in other
wireless networks in an assembly plant. An adjustable
antenna power output function allows the system to limit
electromagnetic “pollution” to virtually nothing. One
EXAConnecT controller can run seven tools simultaneously,
making the system very cost-effective.
Bar code scanners, PLC’s, stack lights and host network
systems can be easily connected to the EXAConnecT
via a combination of built-in I/O ports, RS 422 ports
and Ethernet connections. The system can also run as a
stand-alone without additional hardware. An anti-theft
system prevents the tool from operating out of range of
the EXAConnecT.
The system is unique compared to other products; it does
not require software to communicate with a network or
computer. All information in the EXAConnecT controller
is accessed by using a web browser. All software and
firmware is stored within the EXAConnecT controller. The
system is completely self-diagnostic.
The Bosch Bluetooth system:
Quality control redefined.
The EXAConnecT can control a BT-EXACT tool by workpiece,
fastener and batch count. The OK/NOK signal can be
enhanced (if desired) using run time and other parameters
to accurately determine cross-threading of fasteners or
missing assembly parts; it can detect and limit direction
of rotation to prevent fastener removal. Over 50 different
counting and work/rework strategies can be programmed.
The system can be set to count a batch of fasteners per
job, or report single fastener data. It can control the
assembly line to insure that a worker correctly tightens
the right fastener on the right part at the right time.
Three LED lights on the BT-EXACT tool tell the worker
battery status, if the fastener was properly tightened,
and if the tool is locked, unlocked or out of range of
the EXAConnecT. The system collects and reports all
this data to insure that your assembly process is always
perfect. |

Seven screwdrivers at a single glance:
Powerful tool management software.
Quality control should be easy, not complicated. Our
software combines powerful control, great flexibility and
easy-to-use programming to give you the capability to
control the BT-EXACT tools, the EXAConnecT controller
and your assembly line from anywhere.
The system runs in a web browser without the need for
expensive user interface software. It can be password protected
to insure process security. Take control of
data going to and from the screwdrivers, the controller
and your network in a whole new way.
Clicking on the overview tab lets you view &
control up to seven BT-EXACT drivers running
on one EXAConnecT controller. Each tool
displays antenna signal strength, battery
status, screw count, batch status and joint
condition (OK/NOK shown in green or red).
The serial number and name of each tool is
also displayed. The name of each tool can be
customized for specific applications or
locations within the assembly process. |
|
 |
 |
Clicking on the EXAConnecT tab shows the
detailed data for up to seven tools in real
time. The system can display data such as
driver name, date, time of event, screw run
time, direction of rotation, error messages,
screw count, batch count and additional
input data (like bar code scans or sequence
numbers).
The system also displays the status of the
EXAConnecT controller and lists the devices
that are connected. System error messages
are displayed here, along with detailed
information about the configuration. |
|
 |
|
The system has separate setup screens
for the EXAConnecT controller and the
BT-EXACT tool. The setup screen shows
part of the EXAConnecT setup menu. The
system can be password protected to
prevent unauthorized use.
Each BT-EXACT tool must be “found” and
connected by the controller only one
time; it will remain “connected” until
removed by reprogramming.
Our unique system software can be
configured to effectively stop the system
from interfering with specific Wi-Fi
channels to insure that it does not create interference in an assembly plant. |
|
 |
|
The screwdriver setup menu on the left
controls everything from screw count to
rework strategy to data output choices.
The tool and controller can be setup to
send and receive data from a variety of
systems, including a host ethernet system,
PLC systems, bar code scanners or our
digital I/O module.
The system can also monitor screw run time
to accurately determine crossthreading of
screws or missing parts.
Rework strategies to evaluate the assembly
process can be defined in detail, including
customer-specific programming that is
created by Bosch. |

EXAConnecT wireless controller
The core of the quality control system
The EXAConnecT Bluetooth controller packs a lot of
firepower in a small, easy to install package. The
enclosure is IP 54 (NEMA 12) rated for dust and
moisture resistance.
The controller has its own processor, flash memory
and operating system, so it can run as a stand-alone
unit or connect to a variety of controls.
Various status LED’s and a 2-digit display that can be
seen through the clear cover alert you of connection
status or system errors.
The EXAConnecT controller forms the link between
your process control network and the Bluetooth
equipped BT-EXACT cordless tool. Information
about the screwdriving process can be exchanged
bidirectionally in real time to insure that each
BT-EXACT cordless tool knows exactly what it has to
do and when to do it. One EXAConnecT controller
can run seven tools simultaneously, making it very
cost-effective compared to other error proofing
systems.
The EXAConnecT controller can easily output data
from up to 7 tools via the Ethernet connection, and
up to 4 tools to a PLC via the 24 volt I/O switches.
When controlling 7 tools via a PLC, an accessory digital
I/O module is required.
A wide-range power supply insures the system works
anywhere in the world without the need for additional
power transformers. An internal backup memory and
real-time clock insure that critical data is always saved,
even in the event of a power loss.

The digital I/O box is used with the EXAConnecT
controller. It allows 24 volt I/O signals from up to
seven tools to be sent to a PLC.
The box is IP 54
(NEMA 12) rated for dust and moisture resistance.
The digital I/O module takes its power from the
EXAConnecT controller and receives its tool data from
the controller RS 422 port. The box has 16 switched
input/output connections for communicating with
a PLC. Configuration is done via the EXAConnecT
software (in a web browser).
The EXAConnect controller is capable of supporting up
to 4 tools (via a PLC) with limited I/O data transmission.
The digital I/O module is needed when 2 to 7 tools must
communicate detailed information with a PLC.
The I/O module is not required when using an Ethernet
connection to a host network. There are different
possible PLC configurations for any given situation;
contact your distributor for details.
