Bulletin 1585 Ethernet

Bulletin 1585 is Allen-Bradley's family of industrial Ethernet media — bulk cable spools, RJ45 patchcords, M12 cordsets, and bulkhead adapters engineered for factory-floor EtherNet/IP and other industrial Ethernet deployments. The catalog-number structure encodes every key attribute: the letter immediately after the dash identifies product form (C = bulk spool, J = RJ45 cordset, D = M12 cordset, A = M12-to-RJ45 adapter), the following digit indicates conductor count (4 = 2-pair 100 Mb/s, 8 = 4-pair Gigabit), the jacket code reveals shield type and material (e.g., T = teal TPE unshielded robotic, U = teal PUR foil+braid shielded, H = teal 600V PVC foil shield), and the terminal suffix specifies assembly style — JM for RJ45 male-to-male, DM for M12-to-M12, BJM for M12-to-RJ45 — followed by length (1–75 m for assemblies; 100, 300, or 600 m spools). Popular in-stock items include the 1585J-M8CC-H RJ45 IDC connector, the 1585D-E4GBDE series of 4-conductor M12 D-code cordsets available in 20, 50, and 60 m lengths, and the 1585D-M8TGD4M 8-conductor X-code-to-D-code patchcords in 3, 5, and 10 m versions. Full connector-coding and jacket-specification details are available in the Bulletin 1585 Ethernet Media Technical Data (1585-TD001).
