　　Key Application Scenarios

　　3.1 Wall-Mounted Network Rack CAN Bus Integration

　　The 77253 socket is perfectly matched with 2U-24U wall-mounted network racks used in industrial CAN bus systems, providing reliable signal transmission between rack-mounted CAN bus controllers and external sensors/actuators. Its compact M12 design and pre-molded cable allow for easy routing through the rack’s cable management system without occupying excessive vertical U height. In industrial control room or small-scale industrial data center setups, its shielded structure effectively prevents EMI interference from other rack-mounted equipment, ensuring stable CAN bus communication. The screw locking mechanism ensures secure connection, avoiding loosening caused by rack vibration or environmental disturbances.

　　3.2 Industrial Automation & CAN Bus Network

　　For industrial automation systems (e.g., factory production lines, automotive assembly lines, robotic arms) and CAN bus networks, the 77253 socket’s IP67 protection level and robust PUR housing make it suitable for connecting industrial sensors, servo drive actuators, and PLC modules. Its gold-plated contacts ensure low contact resistance and stable signal transmission, while the shielded design (with shielding layer connected to pin 1) effectively suppresses electromagnetic interference, critical for high-speed CAN bus communication. The socket complies with DIN EN 61076-2-101 standard, ensuring compatibility with mainstream industrial automation equipment and facilitating system integration.

　　3.3 Harsh-Environment Edge IoT Nodes

　　In distributed edge computing nodes and IoT deployment scenarios in harsh environments (e.g., outdoor industrial monitoring stations, mining equipment, agricultural IoT terminals), the 77253 socket’s IP67 dust-tight and waterproof protection enables reliable power and signal configuration. Its wide operating temperature range (-25°C ~ 85°C) and resistance to vibration (up to 5m/s² acceleration) ensure long-term stable operation in extreme conditions. The pre-molded PUR cable with excellent flexibility (fixed bending radius 5x cable diameter, movable bending radius 10x cable diameter) adapts to complex installation routes, reducing deployment difficulty in harsh environments. It supports rapid deployment of IoT sensing networks, meeting the needs of real-time data collection and transmission.

　　Core Advantages for Global Customers

　　Robust Harsh-Environment Design: IP67 protection level ensures dust-tight and waterproof performance, while PUR halogen-free housing and zinc-nickel plated locking nut provide excellent corrosion resistance. Complies with DIN EN 61076-2-101 standard, suitable for high-vibration, high-humidity, and dusty industrial environments.

　　Enhanced EMI Protection & Signal Stability: Shielded structure with shielding layer connected to pin 1 effectively suppresses electromagnetic interference, ensuring stable signal transmission for CAN bus and industrial control systems. Gold-plated copper contacts minimize contact resistance and improve wear resistance, supporting over 100 mating cycles.

　　Secure & Easy Installation: Screw locking mechanism ensures secure connection, preventing accidental disconnection due to vibration. Pre-molded cable design eliminates on-site wiring errors, improving installation efficiency. Standard M12 interface is compatible with most industrial equipment, facilitating quick replacement and maintenance.

　　CAN Bus Optimization: Tailored for CAN bus network applications, with cable specifications (1x2xAWG 22 + 1x2xAWG 24) optimized for high-speed CAN signal transmission, suitable for automotive, industrial automation, and intelligent manufacturing scenarios.

　　International Certification Compliance: Certified by CE, UL, and RoHS, the socket meets the quality and safety requirements of major global markets (EU, US, Asia-Pacific), facilitating smooth customs clearance and market access for overseas customers.

　　Installation & Usage Precautions

　　Before installation, ensure the power supply is disconnected to avoid electric shock. Confirm that the input voltage and current match the socket’s rated parameters (60V, 4.0A) to prevent equipment damage. Do not mate or unmate the connector under load, as this may cause damage to contacts or equipment.

　　When installing in wall-mounted racks or industrial equipment, ensure the connector is fully mated and the locking nut is tightened by hand (approximately 60 cNm) to achieve IP67 protection. Avoid installation in areas with direct exposure to strong chemicals or severe mechanical impact.

　　For circuits with hazardous voltage, secure the locking nut with appropriate cyanoacrylate adhesive to prevent accidental opening (not required for SELV/PELV circuits complying with IEC 61140). Ensure the shielding layer is properly connected to achieve optimal EMI protection.

　　Route the pre-molded cable according to the specified bending radius (fixed: 5x cable diameter, movable: 10x cable diameter) to avoid damaging the cable or affecting signal transmission. Separate the cable from high-voltage power cables to further reduce EMI interference, and use cable management accessories to secure the cable and avoid excessive tension.

　　Regularly inspect the socket for signs of damage (e.g., cracked housing, worn contacts, damaged cable insulation) and replace it immediately if any abnormalities are found. Clean the mating surface periodically to remove dust and debris that may affect contact performance. For outdoor installations, add additional anti-corrosion protection to the connector.
