SAE J2839:2020 pdf free.Heavy Duty High Speed Datalink Connector
High Speed Datalink connection systems, typically those operating at speeds that are greater than 10M bps, have been developed for commercial applications without regard to their potential application on heavy-duty vehicles or off-highway machines. This recommended practice is intended to be the standard for the heavy-duty connector mating interface and environmental performance requirements for High Speed Datalink connection systems. This standardization will assure mating compatibility of data link connectors from multiple connector suppliers while meeting industry performance requirements for heavy-duty applications.
The test requirements apply to the connector-to-connector interface including the connector to cable interface(s), and if applicable, the connector to housing interface for bulkhead mounted connectors.
Cable connectors shall be assembled using 100 ohm土10 ohm impedance 0.8 mm2 and 0.5 mm2 two twisted pair jacketed cable. A braided shield or foil shield with drain wire may be used. The shield shall be terminated to the connector housing per the connector manufacturer’s assembly procedure.
Cables may be constructed from ISO 6722 conductors or SAE J1 128 conductors. The test requirements for 0.75 mm2 conductors shall be the same as those for 0.8 mm2.
Bulkhead connectors shall be mounted per the manufacturer’s assembly procedure. Ensure that the inside elements of a device mounted bulkhead connector are not subjected to the effects of water, salt, chemicals, etc. Environmental performance is applicable only to the mating connector side of a device mounted bulkhead surface. For a cable connector, the measuring point shall be 900 to 1000 mm beyond the point of connection. The cable jacket shall remain for a minimum of 850 mm beyond the point of connection.
For a device mounted bulkhead connector, the terminals are exposed in the interior of the device. The measuring point shall be 0 to 25 mm from the back surface of the bulkhead connector.
Per SAE J2030 Paragraph 6.20. This tests the mated connector interface, the connector to multiconductor cable interface and the bulkhead interface of bulkhead mounted connectors. Use a force of 444N in the axis of the connection. Repeat this test with the cable pull 90 degrees off the axis of the connector. The pull force requirement of HDM12EX connector is 1332.SAE J2839 pdf free download.
