Overview

The TE Connectivity 4-Position M12 Circular Connector (SKU: 394339-E) is a board-mount solution designed for cable-to-board and printed circuit board applications requiring power, signal, and high-speed data transmission. This M12 series connector features a 4-position configuration with A-code keying, ensuring compatibility with standard M12 systems while providing secure, reliable connections in industrial environments. Engineered for harsh conditions, the connector supports power delivery up to 4A per contact, signal integrity for low-voltage applications, and high-speed data transmission up to 100 Mbps, making it suitable for industrial automation, robotics, and machinery control systems. The board-mount design allows for direct soldering to PCBs, eliminating the need for additional mounting hardware and reducing installation complexity. Constructed with durable thermoplastic housing and gold-plated contacts, the 394339-E resists corrosion, vibration, and environmental contaminants such as dust, moisture, and chemicals. The IP67-rated sealing ensures reliable operation in wet or dusty conditions, while the compact M12 form factor optimizes space in densely packed electronic assemblies. Key applications include factory automation, motor control systems, sensor networks, and industrial communication interfaces where compact, high-reliability connectors are essential. The A-code configuration prevents mismating with other M12 codes (e.g., B, C, or X), ensuring system integrity. Compliance with IEC 61076-2-101 standards guarantees interoperability with other M12-compatible devices. With a temperature range of -40°C to +85°C, this connector meets the demands of outdoor and industrial environments. The 394339-E is manufactured in the US, providing traceability and quality assurance for mission-critical applications.
