... not connected Fig. 3: Internal connection of the CAN-T-Connector In the CAN-T-Connector the metal shells of the DSUB connectors are not connected. Thus, the metal shells are not connected through the CAN-T-Connector, see Figure 3. 2.1.2 Usage in Light Industrial Environment (Single Twisted Pair Cable) -

2.1.3 Usage in Heavy Industrial Environment (Double Twisted Pair Cable) When using the esd’s CAN-T-Connector type C.1311.03 with single shielded double twisted pair cables in heavy industrial environment applications, please note that the shield potential of the conductive DSUB housing is not looped through this CAN-T-connector type (see also chapter “Device Cabling”... -

Therefore the practical maximum number of nodes, bus length and stub length are typically much lower. esd has concentrated her recommendations concerning CAN wiring on the specifications of the ISO 11898-2. Thus this wiring hints forgoes to describe the special features of the derived standards CANopen, ARINC825, DeviceNet and NMEA2000. -

3.2.1 General Rules NOTICE esd grants the EU Conformity of the product, if the CAN wiring is carried out with at least single shielded single twisted pair cables that match the requirements of ISO 11898-2. Single shielded double twisted pair cable wiring as described in chapter 3.3. ensures the EU Conformity as well. -

Page 17: Examples For Can Cables
Correct Wiring of Electrically Isolated CAN Networks 3.6 Examples for CAN Cables esd recommends the following two-wire and four-wire cable types for CAN network design. These cable types are used by esd for ready-made CAN cables, too. 3.6.1 Cable for light industrial Environment Applications (Two-Wire) -
