Inductive technology
Regasense RCL40 and RCL41 are inductive linear sensors and the sensors are based on the eddy current
principle. The sensor tube is mounted in the piston of the cylinder and the sensor rod contains a coil. The
sensor will detect the change in inductance that is proportional to how much of the sensor rod is in the
sensor tube.
RCL40 and RCL41 sensors require an RCL-controller to operate. The RCL40 and RCL41 sensor probe can
be used with both variants of controller, so a RCL40-sensor can be used with a RCL41-controller and vise
versa. However the controller is calibrated for a specific stroke length according to the product configura-
tion code.
Scope of delivery
RCL40 or RCL41 sensor with installation accessories:
- 1 pcs support ring
- 1 pcs o-ring
- 2 pcs wave spring washer
- 2 pcs retaining ring
RCL43 controller
RCL41 DIN controller
Sensor and control box are sold separate.
Accessories
Additional accessories, not included in the standard scope of delivery are connectors and cables.
Connectors 6140 is a pressure sealed M12 connector suitable when the installation is not
pressure sealed at the sensor header or/and when the hydraulic cylinder is exposed to extremely harsh
environment requiring a hermetically sealed connector. 6140 suits wire sensors (RCL40) and require
soldering
Connector 6160 is an M12 connector with IP67 protection suitable for applications with pressure seal at
the sensor header. 6160 require no soldering and can be used with sensors with wire connection (RCL40).
When RCL40 is used with 6160 connector, the sensor and connector must be ordered together as the
crimp contacts for the connector are mounted from factory.
Shielded PUR sensor cables with overmolded M12-connector are available in different lengths.
More information on the different connectors and cables are availible in the datasheets.

Installation of sensor rod
Pre-installation checklist
Make sure that there is no damage to the sensor.
• The sensor rod and tube shall be straight and intact without dents and scratches.
• The sensor header shall be intact.
• Make sure that the electrical connection is in good condition. Wires shall be firmly attached to the back-
side of the header and the cable jacket shall be intact.
• Installation accessories shall be in good condition.
The drilling dimensions in the cylinder must be within specified tolerances. Otherwise there is risk of
malfunction and/or vibration can cause increased wear.
Inspekt the controller so the casing, electronic connection etc. is in good condition, free from damage and
contamination such as liquids or dirt.
Installation of sensor tube
1. Place the wave spring washer in the mounting
hole in the piston.
2. Mount the sensor tube in the piston.
3. Fix the sensor tube with the retaining ring.

1. Mount the o-ring and and back-up ring on the sensor header according to drawing below.
Do not install the senor rod without o-ring and back-up ring. The sensor is not designed for hydraulic
pressure on the backside of the sensor header.
2. Feed the sensor wires or cable thru the drill hole in the cylinder body to the location where the con-
nector or cable gland shall be mounted. This step may vary depending on the design of the cylinder.
Make sure that the wires are free from mechanical stress. Do not pull in the wires/cable to pull the
sensor in place.
3. Mount the sensor firmly in place.
4. Fix the sensor in position:
a. By a M4 flat pointed set-screw. Recommended tightening torgue < 2 Nm. Seal the set screw with
suitable sealing compound. The force from the hydraulic pressure shall apply on the back side of
the sensor head against the cylinder body, the set-screw shall not hold this force.
b. Or use the retaining ring: Place the wave spring washer on the header and then install the retaining
ring.
5. Install the electric connection:
a. RCL41: It is recommended to install RCL41 sensors with a cable gland through the cylinder.
b. RCL40: Connect the wires to a suitible connector. Recommended options is 6140 or 6160 and follow
the instructions in this manual. When RCL40 is used with 6160 connector, the sensor and connector
must be ordered together as the crimp contacts for the connector are mounted from factory.

o-ring: 14 x 1,78 mm NBR70. Not included in
scope of delivery.
2. Cut the sensor wires to suitable length.
3. Place heat shrink tube on the wires.
4. Strip 10 mm of the wires and twist them in pla-
ce in the pins of the connector. See connection
in table below.
5. Solder the joints.
Soldering shall be done by personnel with pro-
per training.
6. Heat the heat shrink wires in place over the
solder joints.

Installation of connector 6160
6160 connectors can only be used when the
sensor is pressure sealed at the header.
6160 consists of crimp contacts, splice ring, contact
carrier and flange housing. When a RCL40 sensor is
supplied with 6160 connector the crimp contacts is
crimped to the sensor wires from factory.
1. Assemble the crimp contacts with sensor wire
to the splice ring. Connection shown in table
below.
2. Attach the contact carrier.
3. Insert the o-ring into the groove on the hou-
sing.
4. Slide the contact carrier in the housing until
they snap together.
5. Mount the assembled contact to the cylinder.
Recommended tightening torgue 0.3-0.5 Nm.

Installation of control box
General information
Both RCL40 and RCL41 sensors can be used with both RCL41 and RCL43 control boxes. Choose the control
box best suited for your application. RCL41 control box is designed for DIN mounting and RCL43 control box
is designed with a sealed aluminium housing. The controller can be placed up to 50 meters away from the
sensor.
Do not supply power to the controller until all wires or cables are connected properly for selected
output. Connect the wires from the sensor, power supply and 0V as well as choosen output configuration
before the power is switched on. Find the schematic under the instructions for each controller.
Always use shielded cables to connect the sensor probe and keep in mind that the cable shield on
RCL41 and RCL41P sensor is connected to the header of the sensor. That may cause damage if there is a
potential difference between the location of the sensor and the grounding point of the cable shield.
To ensure proper EMC-performance:
- The shield of the sensor should be connected to an EMC-cable gland when entering the cabinet in which
the controller is placed.
- The sensor wires inside the cabinet should be kept as short as possible.
- If the cabinet contains EMC-noisy equipment there may be need to EMC-protect the wires and the con-
trol box.

Output conguration options
Connect the control box and sensor according the
schematic figure and choose preffered output con-
figuration.
Output signal and jumper settings
The controllers have two parallel outputs; current
and voltage. There are various options for output
signals depending on how the controller is installed,
if no jumper setting is used the standard factory
setting is:
- Increasing output when the piston is moving away
from the sensor head.
- Terminal 4: 4-20 mA
- Terminal 5: 0-5 V
The output can be configured by adding jumper wi-
res to special terminals on the controller according
to the table.
0-10 V output
It is possible to achieve a 0-10V output from the
system. This require a 500 Ω temperature stable
resistor.
- Place a jumper to select 0-20mA output, see table
and schemtic for instructions.
- The resistor should be installed between terminal
4 and 0V. For best EMC-performance place the re-
sistor at the receiving end of the signal (for instance
at the PLC). By doing this the signal is transmitted
using a noise resistant 0-20 mA signal. The voltage
over the resistor is 0-10V.
