DeviceNet connector
DeviceNet Connector Overview A DeviceNet connector is a specialized component designed for use in industrial automation networks, specifically within the DeviceNet protocol—an open, low-level communication system based on the Controller Area Network (CAN) technology. These connectors facilitate reliable data and power transmission between industrial devices such as sensors, actuators, motor starters, and programmable logic controllers (PLCs). Key Features 1. Robust Construction DeviceNet connectors are built to withstand harsh industrial environments, featuring durable materials like high-grade plastics or metal housings. They often include sealing gaskets or IP-rated designs to resist dust, moisture, and vibrations. 2. Power and Data Integration Unlike standard connectors, DeviceNet variants combine power (24V DC) and data communication in a single cable, reducing wiring complexity. They typically have five pins: two for power (V+ and V–), two for CAN signals (CAN_H and CAN_L), and one for shielding. 3. Screw or Push-in Termination Connectors may use screw terminals or quick-connect push-in mechanisms for secure wire attachment, ensuring stable connections even in high-vibration settings. 4. Network Topology Support DeviceNet supports trunk-and-drop topologies, and connectors often include provisions for daisy-chaining devices via T-taps or inline splices, simplifying network expansion. 5. Shielding and Noise Immunity Shielded designs minimize electromagnetic interference (EMI), critical for maintaining signal integrity in electrically noisy industrial settings. Types of DeviceNet Connectors - Open-Style Connectors: Used for device integration, allowing easy attachment to equipment. - Sealed/Molded Connectors: Provide environmental protection for outdoor or washdown applications. - Mini/Micro Connectors: Compact versions for space-constrained installations. Applications DeviceNet connectors are widely used in manufacturing, automotive assembly, material handling, and process control systems where real-time, deterministic communication is essential. Compliance and Standards These connectors adhere to DeviceNet specifications (based on CAN 2.0) and often meet international standards like UL, CE, or IEC for safety and performance. In summary, DeviceNet connectors are critical for industrial networking, offering durability, simplified wiring, and noise-resistant communication—key for efficient automation systems.
