1. Introduction
This document is related to Inxpect SRE 100 Series and 200 Series.
For LBK System, please have a look at the respective documentation.
1.1 Control units
Both Inxpect SRE 100 and 200 Series use one of the following control units:
•Type A control units:
oC201A-PNS
oC201A-F
oC202A
oC203A
•Type B control units:
oC201B-P
oC201B-F
oC202B
oC203B
Please download the Instruction Manual from Inxpect Tools (https://tools.inxpect.com/) to have details about the
differences between the control units.
1.2 Sensors
Each 100 Series control unit can handle up to six S101A sensors.
Each 200 Series can handle:
- up to six sensors type “5 meters range” (S201A, S201A-W, S203A-W), or
- up to six sensors type “9 meters range” (S201A-MLR, S201A-WL, S203A-WL)
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.

200 Series
Page 4/17
2. Technical specifications
2.1 Cable technical data
2.1.1 Inxpect SRE 100 Series
The minimum requirements for the cables are the following:
●Number of conductors: 4 wires and 1 drain wire (or shield)
●Conductor cross-sections (nominal): 0.22 mm² (AWG24) for data signal and 0.22 mm² (AWG24) for
power supply
●Impedance: 120 Ω ± 10% (f = 1MHz).
The recommended cable technical data are the following:
●Signal type/category: CAN bus, CANopen®, DeviceNetTM.
●Number of conductors: 4 wires (twisted pair) and 1 drain wire (or shield)
●Conductor cross-sections (nominal): 0.22 mm² (AWG24) for data signal and 0.34 mm² (AWG22) for
power supply
●Cable Material: PVC (depending on final site of application)
●Cable operating temperature: from -20°C to +80°C
●Impedance: 120 Ω ± 10% (f = 1MHz).
●Others specifications: cable and connectors totally shielded with copper braid tin plated
2.1.2 Inxpect SRE 200 Series
The recommended cable technical data are the following:
●Signal type/category: CAN bus, CANopen®, DeviceNetTM.
●Number of conductors: 4 wires (twisted pair) and 1 drain wire (or shield)
●Conductor cross-sections (nominal): 0.22 mm² (AWG24) for data signal and 0.50 mm² (AWG21) for
power supply
●Cable Material: TPU (depending on final site of application)
●Cable operating temperature: from -20°C to +80°C
●Impedance: 120 Ω ± 10% (f = 1MHz).
●Others specifications: cable and connectors totally shielded with copper braid tin plated
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”.

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)
