5、 J2839 FEB2010 Heavy Duty High Speed Datalink Connector RATIONALE J2839 has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE This SAE Recommended Practice defines the performance requirements, size and mating interfaces for M12 style 4 and 5 pole Heavy Duty High Speed Datalin
6、k connection systems, and applies to both cable-to-cable and cable-to-device connectors. 1.1 Purpose 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 applicatio
7、n 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 dat
8、a link connectors from multiple connector suppliers while meeting industry performance requirements for heavy-duty applications. 2.
