　　Key Application Scenarios

　　3.1 Wall-Mounted Network Rack Power Distribution

　　The 77252 socket is perfectly matched with 2U-24U wall-mounted network racks, especially suitable for PCB-integrated power distribution and signal transmission modules. Its compact low-profile design (dimension: 19.74mm×9.2mm×8.5mm) allows for easy installation in the limited space of wall-mounted racks without occupying excessive vertical U height. In enterprise branch or small data center setups, its 5-position wire-to-board design can efficiently connect rack-mounted sensors, monitoring modules, and PDUs, realizing centralized power supply and signal collection. The standardized 3.96mm centerline spacing enables seamless integration with mainstream PCB boards and rack-mounted electronic components.

　　3.2 Industrial Control System Power Supply

　　For industrial control systems (e.g., factory automation lines, smart production workshops, industrial park monitoring systems), the 77252 socket’s robust ABS housing (halogen-free, UV-resistant) and IP40 dust-proof protection make it suitable for connecting PLC modules, servo drive sensors, and control panels. Its tin-plated brass contacts ensure low contact resistance and stable signal transmission, while the 16A rated current meets the power supply needs of medium-to-high power industrial equipment. The socket complies with EN 50085-2-1 standard, ensuring reliable operation in industrial indoor environments with dust and slight vibration.

　　3.3 Edge Computing & IoT Node Deployment

　　In distributed edge computing nodes and IoT deployment scenarios (e.g., smart cities, remote environmental monitoring stations, smart factory edge terminals), the 77252 socket’s compact size, wire-to-board design, and excellent environmental adaptability enable quick and reliable power and signal configuration. It supports rapid deployment of PCB-integrated edge computing infrastructure, meeting the needs of long-term stable operation of edge servers, IoT sensing devices, and data collection terminals in industrial indoor or semi-outdoor auxiliary environments. The reliable mating stability and standardized design reduce wiring complexity and maintenance costs.

　　Core Advantages for Global Customers

　　Robust Industrial-Grade Design: ABS housing with halogen-free and UV-resistant properties, complying with EN 50085-2-1 standard. The IP40 dust-proof protection level ensures stable performance in industrial indoor environments with dust and slight vibration.

　　Enhanced Transmission Performance: Tin-plated brass contacts minimize contact resistance, ensuring stable power supply (16A rated current) and signal transmission. The 5-position wire-to-board design realizes integrated transmission of power and signal, reducing wiring complexity and improving system integration efficiency.

　　Space-Saving & Easy Installation: Compact low-profile structure and standardized PCB vertical mounting design allow direct installation on rack-mounted PCB boards using through-hole soldering. Compatible with most mainstream rack models and industrial control enclosures, maximizing space utilization.

　　Wide Compatibility: Standard 3.96mm centerline spacing is compatible with most wire-to-board connectors and mainstream industrial PCB boards, facilitating system expansion and component replacement for global customers.

　　International Certification Compliance: Certified by CE, UL, RoHS, and EN 50085-2-1, 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 (250V, 16A) to prevent equipment damage.

　　When installing in wall-mounted racks or industrial control panels, select a position away from heat-generating equipment and ensure adequate ventilation around the socket to prevent overheating. Avoid installation in areas with direct exposure to water or heavy oil.

　　Use dedicated mounting screws to fix the socket, ensuring it is firmly attached to avoid loosening due to equipment vibration or industrial site disturbances.

　　When connecting cables, adopt through-hole soldering for PCB mounting to ensure reliable contact (recommended for wire-to-board connectors). Route power and signal cables through separate channels to avoid EMI interference, and use cable management accessories to secure cables. Avoid excessive force during mating to prevent damage to contacts.

　　Regularly inspect the socket for signs of damage (e.g., cracked housing, loose contacts) and replace it immediately if any abnormalities are found. Clean the socket surface periodically to remove dust and debris that may affect contact performance, especially in dusty industrial environments.
