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
