Adapter M12 D-coded 4-pin (male) to RJ45 plug, DELOCK 90831, gold-plated contacts, black

DELOCK M12 adapter converts an M12 D‑coded 4‑pin male connector into a standard RJ45 plug, allowing RJ45‑equipped devices to connect to M12 D‑coded ports common in industrial Ethernet, sensors and automation systems. The adapter has gold‑plated contacts and a PVC housing in black, designed for reliable signal transmission and resistance to corrosion in industrial environments.

Advantages

The adapter offers a compact solution to bridge devices with M12 D‑coded interfaces and standard RJ45 Ethernet equipment without rewiring. Gold‑plated contacts improve conductivity and corrosion resistance, while the PVC housing provides basic mechanical protection and electrical insulation in typical industrial settings.

Suitable for

• Industrial Ethernet connections requiring D‑coded M12 4‑pin interfaces
• Connecting industrial cameras, sensors or fieldbus devices to RJ45 ports
• Temporary test setups and machine maintenance where quick adapter use is needed

When it may not be suitable

This adapter is intended for signal and data connections using the D‑coded M12 4‑pin standard and RJ45 interfaces; it is not designed for power delivery beyond typical Ethernet power levels. It may not be appropriate where IP‑rated, ruggedized, or vibration‑resistant sealed connectors are required for harsh outdoor or washdown environments.

Key specifications

• Connector A: M12 D‑coded 4‑pin (male)
• Connector B: RJ45 plug (male)
• Contact plating: gold
• Housing material: polyvinyl chloride (PVC)
• Color: black
• Quantity: 1 piece

How to use

Insert the M12 male side into the corresponding D‑coded M12 female port and plug the RJ45 end into the Ethernet device or cable. Ensure correct alignment of the D‑coding to avoid improper mating, and secure connections on both sides. Use the adapter for data transmission in accordance with the connected equipment's specifications.

What to consider before purchase

• Confirm your device uses M12 D‑coded 4‑pin ports (not other M12 codings)
• Check that RJ45 compatibility meets your network speed and wiring requirements
• Assess whether a sealed or higher‑grade rugged connector is needed for your environment

Usage recommendations

For stable connections, ensure contacts are clean and connectors are properly seated; avoid using the adapter as a permanent substitute for purpose‑built cabling in environments requiring high ingress protection or mechanical strain relief.
