　　Key Application Scenarios

　　3.1 Wall-Mounted Network Rack Power Distribution

　　The 77210 socket is perfectly matched with 2U-24U wall-mounted network racks, providing centralized and reliable power supply for multiple rack-mounted devices. Its compact rectangular design (dimension: 27.81mm×24.64mm×15mm) allows for easy installation in the limited space of wall-mounted racks without occupying excessive vertical U height. In small office or enterprise branch network setups, it can supply power to switches, routers, patch panels, and intelligent monitoring sensors simultaneously, ensuring stable operation of the entire network system. The standardized pitch design enables easy integration with mainstream rack power distribution units (PDUs).

　　3.2 Industrial Control System Power Supply

　　For industrial control systems (e.g., factory automation lines, industrial park monitoring systems), the 77210 socket’s wide operating temperature range (-55°C ~ 105°C) and robust nylon housing make it suitable for powering industrial control panels, PLCs, and IoT gateways. Its dust-proof (IP40) protection level ensures reliable operation in industrial environments with high dust concentrations, effectively preventing dust from entering the socket and affecting contact performance.

　　3.3 Edge Computing & IoT Node Deployment

　　In distributed edge computing nodes and IoT deployment scenarios (e.g., smart cities, remote environmental monitoring stations), the 77210 socket’s compact size and excellent environmental adaptability enable quick and reliable power configuration. It supports rapid deployment of temporary or fixed edge computing infrastructure, meeting the needs of long-term stable operation of edge servers and IoT sensing devices in harsh outdoor or remote environments.
