Receptacles and
Cordsets
The Brad® Micro-Change® M12 Heavy-Duty Ethernet
System achieves high-speed data link rates up to 10/100
Mbps, exceeds standard M12 connector pull-force strength
10-fold and is designed based on the J2839 specification
Brad® Micro-Change® Heavy-Duty Ethernet cordsets and receptacles are
designed for use in harsh environments with wide temperature variations.
Molex is first to offer both HDM12 and HDM12EX connectors. The M12-style
cordsets are ideal for high-speed Ethernet networks. The sturdy design
ensures the connectors will withstand high-vibration levels in chassis
applications.

Micro-Change Heavy-Duty High-Speed Ethernet cordsets are heavy-duty
versions of standard Micro-Change connectors and receptacles.
Molex was an integral participant in the Society of Automotive Engineering
(SAE) committee, which defined the J2839 standard for a rugged and robust
connector for heavy-duty and off-highway vehicles.
The standard defines the performance requirements, size and mating
interfaces for M12 style 4- and 5-pole heavy-duty, high-speed data-link
connection systems.
