A 5-meter M12 12-pole cable with a straight male plug at the device end and open ferrules at the cabinet end—purpose-built for SIMATIC RF readers that require all 12 conductors for power, RS422 data, and digital I/O on a single M12 connector. The PUR jacket handles oil, UV, and flexing in industrial machine environments.

When do I need 12 poles instead of 4?

Standard 4-pole M12 cables carry power (2 wires) and one data pair. Twelve-pole cables support RS422 communication (4 data wires), multiple digital I/O channels, and power—all through one connector. SIMATIC RF600 readers with full RS422 + DI/DO functionality require the 12-pole interface. Using a 4-pole cable where 12 poles are needed leaves I/O signals unconnected.

How do I terminate the open end?

The open-end conductors use color-coded ferrules per DIN 47100. Land them directly on cabinet terminal blocks or crimp to a D-sub connector for the controller interface. Keep the shield drain wire connected to functional earth at the cabinet end.
