The first connector system to comply with SAE J2839 standard

Molex has introduced its Brad Micro-Change M12 Heavy-Duty Ethernet Connector System – the first M12 system to comply with the SAE J2839 heavy-duty, high-speed datalink standard.

Cat 5e compliant for 10/100Mbps Ethernet speeds, the new connector system meets the needs of commercial vehicle and off-highway machine manufacturers seeking M12 Ethernet solutions for use in extremely harsh environments.

“Molex worked hand in hand with the Society of Automotive Engineering (SAE) committee, which defined the SAE J2839 standard for rugged and robust connectors,” said Ted Szarkowski, product manager, transportation and industrial solutions, industrial business unit, Molex.

“The Brad Micro-Change M12 Heavy-Duty Ethernet Connector System was developed through this collaboration, and delivers proven results.”

The SAE J2839 standard defines the performance requirements, size and mating interfaces for M12-style 4-pole heavy-duty, high-speed data-link connection systems for use in harsh environments with wide temperature variations. Both HDM12 and HDM12EX receptacle and cordset options are available – supporting 444N (HDM12) or 1334N (HDM12EX) of pull force resistance – ten times stronger than industry standard M12 connectors. They also withstand a wide operating temperature range of -55 to +125°C.

Backward-compatible to standard Brad Micro-Change M12 connectors, the new connector system simplifies the upgrade process to the heavy-duty standards and complies fully to IEC 61076-2-101 standards. The unique, stainless steel impregnated overmould material assures 360° shielding effectiveness, optimizing signal performance without system noise interference. The sealed connector system is IP67 and IP69k compliant, sealing against water at depths up to 1m and withstanding high-pressure wash downs.

“The full Brad Ethernet offering – from software to connectors – provides customers a complete connector system for commercial vehicle and off-highway machine manufacturers seeking M12 Ethernet solutions for use in extremely harsh environments,” added Szarkowski.
