Overview

The TE Connectivity 4-Position M12 Circular Connector (SKU: 2351378-2) is a hermetically sealed, cable-to-cable interconnect designed for reliable signal transmission in harsh industrial environments. Constructed with a nickel-plated copper alloy housing and a durable nylon body, this connector delivers exceptional corrosion resistance and mechanical strength, ensuring long-term performance in demanding applications. The D Code configuration provides secure, polarization-protected connections, while the sealable design resists moisture, dust, and mechanical stress. With a compact M12 form factor, this connector is ideal for space-constrained installations in automation, industrial control systems, and electronics operating in extreme conditions. The reverse gender design allows for flexible cable-to-cable configurations, and the hermetic sealing meets stringent environmental protection requirements. Compatible with standard M12 signal cabling, this connector supports up to 4 signal positions, making it suitable for low-voltage control, sensor, and communication applications. The nickel-plated contacts ensure low contact resistance and long-term reliability, even in high-vibration environments. Trusted by engineers worldwide, this TE Connectivity solution adheres to industrial standards for durability and electrical performance.
