April 19, 2017 – Molex has introduced its Brad Micro-Change M12 Heavy-Duty Ethernet Connector System – the first M12 system to comply with the SAE J2839 datalink standard. Cat 5e compliant for 10/100 Mbps Ethernet speeds, the connector system meets the needs of commercial vehicle and off-highway machine manufacturers seeking M12 Ethernet solutions for use in extremely harsh environments.
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 - 10x stronger than industry standard M12 connectors. They also withstand an operating temperature range of -55 to +125°C.
Backward-compatible to standard Brad Micro-Change M12 connectors, the connector system simplifies the upgrade process to the heavy-duty standards and complies fully to IEC 61076-2-101 standards. The stainless steel impregnated overmould material assures 360° shielding effectiveness, optimising 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.
