Allen-Bradley 889D-F4AC-2 889 DC Micro Cable

Configured for sensor-to-controller signal and power connectivity in industrial automation systems, the Allen-Bradley 889D-F4AC-2 (889D-F4AC DC Micro Cable) provides direct electrical connection between M12-equipped field devices and control system termination points. The assembly incorporates a straight female DC Micro connector on one end and flying leads on the opposite end for custom field wiring.

Hardware Specifications

Deterministic Field Device Connectivity

The 889D-F4AC-2 is designed for point-to-point connection of sensors, proximity switches, photoelectric devices, and other field instruments utilizing M12 DC Micro interfaces. The four-conductor arrangement supports power distribution and discrete signal transmission between field devices and PLC input modules.

The unshielded cable construction is suitable for general-purpose industrial wiring applications where additional shielding is not required by the installation environment. IEC conductor color coding simplifies field termination and device replacement activities.

The flying-lead configuration allows direct termination into terminal blocks, distributed I/O modules, control cabinets, and field junction points without requiring a secondary connector assembly.

Firmware Compatibility and Network Integration

As a passive interconnection component, the 889D-F4AC-2 does not depend upon firmware revisions or protocol-specific software compatibility. The cable functions as a physical-layer connection medium and may be used with Allen-Bradley and third-party industrial devices employing compatible M12 electrical interfaces.

The M12 connector architecture supports rapid installation, maintenance replacement, and standardized field wiring practices throughout distributed automation systems.

Field Installation Guidelines

• Verify pin assignment compatibility before connecting field devices.

• Maintain conductor separation from high-power motor and drive cabling where practical.

• Tighten the M12 coupling nut fully to ensure proper mechanical retention.

• Protect flying-lead terminations using appropriate terminal blocks or enclosure-mounted wiring accessories.

• Avoid excessive cable bending near the connector body.

• Confirm conductor identification using the IEC color code before energizing field circuits.

• Inspect cable jackets periodically for abrasion, cuts, or environmental damage.
