Please download the Instruction Manual from Inxpect Tools (https://tools.inxpect.com/) to have details about the
differences between the sensors.
1.3 Cables
Both Inxpect SRE 100 and 200 Series require the use of cables with specific features.
The following chapters describe the technical details of these cables.

Cables specifications - Inxpect SRE 100 and
200 Series
Page 4/17
2. Technical specifications

2.2 Length of the CAN bus cables
2.2.1 Inxpect SRE 100 Series
The maximum cable length allowed is 30 metres for each bus line (maximum two bus lines allowed), regardless
of the conductor section of the CAN bus cable.
This value can be reached with a cable only or with multiple cables in case of multiple S101A sensors installed
(chain of sensors). In other words the sum of all the cables used in a single bus line does not have to exceed the
maximum length allowed.
Examples:
●Only a sensor installed

Cables specifications - Inxpect SRE 100 and
200 Series
Page 5/17
●Multiple S101A on the same bus line (chain of sensors)
The sum of the length of each cable must be equal or lower than 30 metres. 󰇛
 )
●Multiple sensors in two different bus lines with the control unit inside of the chain (*)
The sum of each cable’s length on the same bus line must be equal or lower than 30 metres, and the overall
length must be at maximum 60 metres. 󰇛

  , where  6 ). Each bus line may
have between 1 and 5 sensors. The maximum number of S101A sensors managed by a single control unit is 6.
(*) When the control unit is inside of the chain, it is necessary to exclude the termination resistance on the control
unit itself using the DIP Switch “A”.

Cables specifications - Inxpect SRE 100 and
200 Series
Page 6/17
2.2.2 Inxpect SRE 200 Series
The maximum length allowed of the whole CAN bus line (from termination to termination) is 100 metres,
regardless of the conductor section of the CAN bus cable.
A maximum number of two bus lines is allowed. Then, the sum of the length of the two lines must be lower (or
equal to) 100 metres.
Please use the Inxpect SRE 200 Series Cable Validator tool to check and validate your desired cable
configuration.
The tools is going to request the following parameters:
- number of BUS lines (one/two)
- number of sensor for each line (up to six)
- length of each cable*
- Power Supply cable section**
* See sections 3.1.2 and 4.1.2 to know the standard lengths provided by Inxpect
** Standard cables provided by Inxpect have a power supply section of 0.50 mm² (AWG21)
2.2.2.1 Examples (Inxpect SRE 200 Series)
●Example 1 - Multiple sensors on the same bus line (chain of sensors), a valid configuration
In the following example we have:
- number of BUS lines: 1
- number of sensor for each line: 3
- length of each cable: 10+5+10 [m]
- Power Supply cable section: 0.50 mm²

- number of sensor for each line: 6
- length of each cable: 15+5+10+3+2+2 [m]
- Power Supply cable section: 0.50 mm²

- number of BUS lines: 2
- number of sensor for each line: 3+3
- length of each cable: 10+5+10 [m] and 5+5+5 [m]
- Power Supply cable section: 0.34 mm²

●Example 4 - Multiple sensors in two different bus lines with the control unit inside of the chain (*), a not
valid configuration
In the following example we have:
- number of BUS lines: 2
- number of sensor for each line: 4+2
- length of each cable: 15+5+7+10 [m] and 10+5 [m]
- Power Supply cable section: 0.34 mm²

Page 11/17
(*) Each bus line may have between 1 and 5 sensors. The maximum number of S201A sensors managed by a
single control unit is 6.
When the control unit is inside of the chain, it is necessary to exclude the termination resistance on the control
unit itself using the DIP Switch “A”.
3. Cable between the control unit and the first
sensor
The cable between the control unit and the first sensor must have an M12 female connector “A-coded” in order to
plug into the first sensor, and free wires to plug in the control unit screw terminal.
The connector may be straight or 90° angled. In case of installation with the sensor anchored to a vertical plane
the 90° angled version is suggested (example: wall installation).
Example picture:
In the case of purchased cable from Inxpect the cable schematics and colour association is the following.

Notes:
●the shield wire must be connected to EARTH in the electrical cabinet
●in Inxpect cable with conductor section of 0.50 mm² (AWG21) for power supply, a light-blue cap is
present at the end of the shield wire to better distinguish it from all the other wires.
