Intelligent devices with networking functions are the basis of the Internet of things. Machines communicate with each other to achieve status monitoring, use tracking, replenishment of consumables, automatic maintenance, and new entertainment. The ultimate goal is to achieve unattended, self-detection and self optimization. With the progress of technology and the popularization of wired and wireless, the number of intelligent devices can eventually reach tens of billions, as well as the physical I/O interfaces and interconnection products that are tens of times as many as nodes. The connection system widely used in industrial network is 8-pin RJ45 connector. For this type of continuity, the transmission quality of the module socket connector system is excellent, gradual and economical, and its termination mode is welding or surface mount termination. In addition to single port, combined port and stacked port, many product combinations also include filter module socket. Typical module sockets are 4, 6 or 8-pin type, providing unshielded or various shielded options. The dimension drawing of the filter module socket and the printed circuit board layout are similar to the standard type signals, which can be transmitted to the front board through the panel socket or panel coupler. The filter module socket product portfolio also includes the power over Ethernet (POE) type. For applications that need to meet the IEEE802.3af conditions, the filter module socket provides the corresponding power through the data dual line or the idle dual line. In this way, the standard CAT-5 cable can be used for data transmission and power supply up to 100m away. As for the receiver, the 48V power supply can be converted to, for example, 5V or 3.3V. The flexible field bus connector based on D-Sub interface technology is used for general bus systems, such as CAN Bus, Profibus and SafetyBUS in the IP-20 range. This type of product portfolio includes switches (connectable terminal resistors), pure nodes and pure terminals. Different installation conditions lead to different requirements for various cable routes. The fieldbus connectors and cables are often very strong, requiring stable and reliable mechanical stress relief. In the past, the controller in the switch cabinet used I / O cards to drive field devices. Nowadays, industrial automation tends to decentralized systems. Field brakes and sensors are often connected to a passive or fieldbus capable I/O box. In order to provide solutions for a variety of applications at low cost, specific field devices need high-level modular flexible connector solutions. M2M has reached a turning point and is currently growing at an annual growth rate of 25%. In a few years, the number of intelligent connected devices will exceed the population by several orders of magnitude. Therefore, it is difficult to specifically list the application of connectors in the Internet of Things, because industrial connectors are actually a "hodgepodge", and M2M is the catalyst of this industry. An unquestionable trend is that intelligent networked machines will become the next application market of connectors.
