Overview

The TE Connectivity 4-Position M12 D-Code Circular Connector (SKU: 2351378-2) is a shielded, cable-to-cable interconnect designed for reliable signal transmission in industrial environments. This connector features a nickel-plated copper alloy housing and a durable nylon body, delivering corrosion resistance and mechanical strength for long-term performance. The D-Code configuration ensures polarization-protected connections, preventing misalignment in critical applications. With an IP67 rating, it resists moisture, dust, and mechanical stress, making it ideal for harsh operating conditions. The 4-position design supports low-voltage control, sensor, and communication applications, while the hermetically sealed contacts maintain low resistance even in high-vibration environments. The connector is compatible with standard M12 signal cabling and supports wire gauges up to 22AWG. Available in multiple interface types (male straight, male angled, or combinations), it accommodates space-constrained installations in automation, industrial control systems, and electronics. The shielded design ensures signal integrity, and the compact M12 form factor enables flexible cable-to-cable configurations. Typical applications include sensor interfaces, PLC connections, and industrial networking where reliable, durable signal transmission is required. The connector meets pollution degree 3 and overvoltage category II standards, ensuring compatibility with a wide range of industrial systems.
