German AWAIBA plug AWAIBA model AWAIBA price

AWAIBA plug is a connector used to connect serial and parallel cables to a data bus. The naming format for data bus connectors is DB-x, where x represents the number of wires inside the connector. Each wire is connected to a pin in the connector, but in many cases, not all pins are assigned a function. Data bus connectors are defined by various EIA/TIA standards. It is a type of connector used to connect serial and parallel cables to a data bus. DB connectors are named in the DB-x format, where x represents the number of wires inside the connector. Each wire is connected to a pin in the connector, but in many cases, not all pins are assigned a function. DB connectors have 9, 15, 25, 37, and 50 pin sizes. DB connectors define the physical structure of the connector, not the purpose of each wire. For example, DB-9 has 9 pins and is used to connect a mouse. DB-25 has 25 pins and is used to connect a printer.

AWAIBA Plug Introduction

As automation technology has evolved from standalone machine control to Factory Automation FA and then to system automation, the factory automation information network can be divided into the following three-tier structure: factory management level, workshop monitoring level, and field device level. Fieldbus is the communication network between devices at the bottom layer of the factory. Here we first introduce Ethernet, specifically Industrial Ethernet. Industrial Ethernet is an industrial network protocol derived from the office automation domain; by convention, it mainly refers to the IEEE 802.3 protocol. If the TCP/IP protocol suite is further adopted, it is expressed as "Ethernet + TCP/IP". Its technical characteristics are primarily suitable for information management and information processing systems, and it has achieved tremendous success in the IT industry. In the field of information integration at the factory management level and workshop monitoring level, Industrial Ethernet already has many successful cases, and there are also many applications at the device layer where real-time performance is not strictly required. Due to the wide variety of fieldbuses and inconsistent standards, many people hope that Ethernet technology can penetrate the lower layers of devices and widely replace existing fieldbus technologies. Schneider Electric is an active advocate and practitioner of this idea, with a range of industrial-grade products already available and put into practical application. However, since Ethernet cannot truly solve real-time and determinism issues, most field layers will still prefer fieldbus technology. Due to technological limitations and conflicts of interest among various manufacturers, the current situation of coexistence of multiple industrial bus technologies and continuous penetration of Ethernet technology will persist for some time. Users can select the required solution based on technical requirements and actual conditions.

AWAIBA Plug Material

Material selection is based on a comprehensive consideration of processability, product applicability, and strength properties. The cost of electronic connectors varies depending on material prices, processing difficulty, and production efficiency. Electronic connector materials mainly include insulator materials (plastic raw materials) and conductor materials (phosphor bronze, brass). Common engineering plastics for electronic connectors include: LCP, NYLON, and PBT. 1) LCP: Features a low coefficient of linear expansion, low injection molding shrinkage, outstanding strength and elastic modulus, and excellent heat resistance. It has a high heat deflection temperature, with some grades exceeding 340 degrees. LCP also offers excellent chemical resistance and air tightness. Therefore, LCP is the preferred material for general connectors, especially those requiring SMT, such as eg:MINI PCI EXPRESS; DDR. 2) NYLON: Lower cost, very high tensile strength, outstanding wear resistance and self-lubricity, good flowability beneficial for thin-wall molding. However, it shrinks significantly and is prone to burrs. Strict baking is required before molding to prevent hydrolysis. General connectors, especially DIP, mostly use NYLON material, such as eg:PCI 120P; PCI EXPRESS. 3) PBT: Plug-in electronic connectors. Low cost, high strength, wear-resistant, but poor moldability and significant shrinkage. Due to the lower melting temperature, plastic melting may occur during wave soldering.

AWAIBA Plug Operation

A bus operation process completes the transmission of information between two modules. The master module initiates the operation process, and the other is the slave module. At any given moment, only one master module can occupy the bus. Bus operation steps: The master module requests bus control rights, and the bus controller makes the arbitration. Error checking during data transmission: After obtaining bus control rights, the master module addresses the slave module, and data transmission proceeds after confirmation from the slave module. Bus timing protocol: Timing protocols ensure synchronized operation and correct transmission between both parties. There are three types of timing protocols: Synchronous bus timing: All modules on the bus share the same clock pulse to control the operation process. All actions of each module occur at the start of the clock cycle, and most actions are completed within one clock cycle. Asynchronous bus timing: The occurrence of an operation is determined by specific signals from the source or destination module. The occurrence of an event on the bus depends on the occurrence of the previous event, with both parties providing handshake signals.
