## Summary description

DELOCK M12 adapter (model 90831) converts an M12 D-coded 4-pin male connector to a standard RJ45 plug. It features gold-plated contacts for reliable signal transmission and corrosion resistance. Designed for industrial Ethernet and sensor interfaces that require D-coded M12 connections, it enables connection of RJ45-equipped devices to M12 ports in factory and automation environments.

## Long description

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.
