M12 connector to RJ45 adapter

M12 connector to RJ45 adapter is a high-reliability network connection solution designed for industrial environments, supporting quick adaptation of M12 and RJ45 interfaces. It uses brass nickel-plated contacts and plastic shells, has IP68 waterproof and dustproof performance, and is equipped with a screw locking mechanism to ensure a stable connection, which is suitable for harsh industrial scenarios. The product provides a variety of sizes and male and female interface options, compatible with 4-pin/8-pin configurations, and can be flexibly adapted to sensors, industrial cameras, automation equipment, etc., to help achieve efficient and stable data transmission

1. Product Features
High protection level and durability
The adapter shell is made of high-strength plastic, and the internal contacts are made of brass nickel-plated material, which can effectively prevent corrosion and oxidation; the waterproof level reaches IP68, adapting to harsh environments such as moisture and dust, and ensuring long-term stable operation.
Flexible interface and customized design
Supports multiple interface types such as M12 male/female, straight/elbow, and the male and female interfaces can be freely combined to meet the docking needs of different devices. At the same time, it provides two pin core configurations of 4 pins (10BASE-T) and 8 pins (100BASE-TX), which are suitable for industrial Ethernet, fieldbus and other scenarios.

2. Product size and number of pins


Dimensions and specifications: Provide M12 * 1.0, M12 * 1.1, M16 * 1.5 and other thread specifications, suitable for different installation apertures; the main body length covers 45-65mm (refer to the dimension diagram), the interface outer diameter is 34.5-48.5mm, and is compatible with mainstream cables and equipment interface spacing.
Number of pins configuration: Supports two pinhole arrangements: Type A (8 pins) and Type D (4 pins): Type A 8-pin male/female pins are symmetrically distributed in a ring (such as male pins 1-8 are arranged clockwise, and female pins are arranged in the opposite direction), suitable for high-speed network transmission; Type D 4-pin core adopts a compact layout (such as male pins 1-4 are arranged linearly), which meets the basic signal connection requirements, has strong compatibility, and can flexibly match the electrical performance requirements of different devices.
