Ethernet cable Master to Node

Overview

Attention: Please note that all cables delivered by Synapticon are for development and testing purposes only. Make sure that the cables used in production comply with the requirements of your application in terms of bending or torsion.

The Master to Node cable - displayed below - is used to connect an EtherCAT master PC to a SOMANET Node.

  • RJ45 to 5-pin-Molex-PicoBlade STP cable

Master to Node Cable Assembly Specifications

Attention: For connecting EtherCAT devices only, use Ethernet cables that meet the requirements of at least category 5 (Cat5) according to EN 50173 or ISO/IEC 11801. Additionally, the cable and its wires should meet the minimum EtherCAT standard requirements.

* Any that meet the EtherCAT standards.

** According to EtherCAT standards.

In addition:

  • Shield wires must be protected with a shrink tube or similar.

  • It is recommended that the distance from the connector to the cable jacket be 30 mm.

  • All the wires should be of the same length, or as much as possible of the same length, in order to prevent tensions in different wires.

  • Insulation Voltage: The cable should be able to withstand a maximum voltage of 100 V wire-to-wire and wire-to-shield. If higher voltages are required according to EtherCAT standards, the EtherCAT standards have a higher priority.

  • Each transition of cable to connectorized wires must be secured/protected with a shrink tube that is lined with adhesive. This prevents the shrink tube from sliding off. Refer to Figure 1. below.
