4.2 Brief description
Overview
This actuator is to be used exclusively for installation into a
dynamic centric-compression or tensile-loaded lift.
The linear actuator consists of a motor part (4),agearunit
(7) and a linear unit (3),connectedwitheachother.
The actuator consists of a direct current motor with helical
gearwhichsetsinmotionageartransmissionsystem.Via
thedrivingscrewandnut,therotationofgearistransformed
into a linear motion of the actuator.
The front hinge head (1) and the rear hinge head (6) transmit
the actuator power to both sides of the application.
DependingtheCAHB-2xEversion,theextensiontubecan
rotate and must be fasten on the application to avoid the ro-
tation and provide the linear movement. In option for the
CAHB-2xE,thetubecangetanantirotation.Theanti-rota-
tion of the tube is a standard feature of the CAHB-2xS
Fig. 11
4.3 Special features
Mechanical overload protection
The actuator contains a mechanical overload protection unit
(clutch).This overload protection unit will activate if the linear
unit of the actuator overloads. This activation will avoid to
pushorpulloverthemaximumforcedenedonthedata-
sheet and will protect the motor and gear unit from being
damaged.
CAUTION
Continued operation of the clutch can result in overheating and
damagetothelinearactuator.Ifclutchactivates,switchoffpower
immediately.
Integrated controller (S design only)
The smart version has a built-in electronics controller with
H-bridge and 2 micro controllers . This integrated controller
provides multiple functions described bellow.
Unique true absolute position sensor
(S design only)
A unique absolute positioning system equipped all smart
CAHB-2xS.Basedongearsandnocontactsensors,the
tube position generate an absolute signal in-stead of an in-
cremental signal. The actuator will never lose the position
even if the tube of the actuator is moving when the actuator
is not powered. No need of calibration to keep the full per-
formance during the ac-tuator life.
Electronic overload protection
(S design only)
An electronics over load protection limits the current draw by
acurrentcut-o,sotheforcethattheactuatorcanpushor
pull.Thetemperatureeectontheperformanceiscompen-
sated by the micro controller after a calibration done at the
end of line test of the actuator assembly line.
Soft start / soft stop (S design only)
The soft start and soft stop with a ramp up and ramp down
during 200 ms is set on the controller in order to limit the dy-
namiceectoftheaccelerationanddec-celarationandget
a smooth movement.
16
CAHB-20 series
Adjustable end stop (S design only)
The smart CAHB-xS are delivered with the end stop accord-
ing to the retracted length and the stroke length of the actu-
ator (see the ordering key). If the application on the equip-
ment or the vehicle request an adjustment of the retracted
andextendedlength,asimpleandsafelearningprocedure
by the 2 motion inputs or by CAN bus will memorized the re-
quested lengths.
Monitoring and Diagnostic
(S design only)
Thekeyparameteroftheactuatorlikecurrent,voltageand
environmental data like the temperature are tracked and re-
cordedincaseofoverspecication.Thediagnosticisavail-
ablethroughthebuscommunication,soonboardiftheac-
tuatorisconnectedtoanElectronicControleUnit,ECU,by
theCANbusoro-boardiftheCANbusisconnectedonly
during overhaul and maintenance of the equipment or the
vehicle.
Bus communication (S design only)
A bus communcation CAN bus SAE J1939 equipped all
smart CAHB-2xS actuator. It could be used to have ad-
vanced control of the actuator like go to a position or oper-
ate at a lower speed but also to read the monitoring and get
the diagnostic.
Parallel motion option (S design only)

motion until the stop. A command to any actuator of the
groupwillbeenoughifallactuatorswerepredened.Allac-
tuators will monitor their relative position and will decide to
follow the slowest actuator. No downgrade speed perfor-
mance,themovementwillrunatthefastestspeeddepend-

Position, speed and force control.
The CAHB2-xS can receive a command by CAN bus to con-
trolthelengthsetin0.1mm,aspecicspeedsetin%ofthe
maximum speed and maximum force set in N. The move-
ment will be monitored to follow the command including a
soft start and soft stop to perform a smooth movement.

4.6.3 Absolute analog position output
E design
The absolute analog position sensor is a multitude non-con-
tact magnetic sensor. It provides a signal indicating the posi-
tionofthelinearactuator.theoutputsignalis0~5VDCvolt-
age(currentoutput5mAmax).Theelectricalspecication
andresolutionrefertodatesheet,thewiresconnectingrefer
to 6.4.1 Wiring scheme.
NOTE
WhenactuatorwithPOTortheanalogoutput,don’trotatethepush
tube 45 degree and don’t connect to power before the actuator is
installed into device (see picture below) Otherwise would demage
the potentiometer or the analog sensor components.
WARNING
S design
The absolute analog position output is simulated by smart
PCBA. It provides a signal indicating the position of the lin-
earactuator.Theoutputsignalis0~5or0~10VDC(current
output 15 mA max) depending of ordering key selection. The

4.6.4 Encoder
E design only
Dual hall sensor for incremental position feedback. It out-
puts signals when the actuator is moving outwards and in-
wardsrespectively.Theoutputsignals,channel1and2,are
±90°,seethegurebelow.Theelectricalspecicationason

4.6.5 Termination resistor integrated
S design
The termination resistor can be integrated in the actuator.
Thus there is no need to connect termination resistor at CAN
circuit.
The termination resistor value is 120 ohm.
4.6.6 Manual Override
Manual override option provides a solution to move the push
tube manually and without tool when power failure. The un-
screwed cover can be used as a hand crank. With the
CAHB-2xE,apowertoolcanbeusedtodrivethecoverby
