German Hetronik plug Hetronik model Hetronik price

Hetronik 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.

Hetronik Plug Introduction

As automation technology evolved from standalone control to factory automation FA, it developed into system automation. The factory automation information network can be divided into the following three-layer structure: factory management level, workshop monitoring level, and field device level, while the fieldbus is the communication network between bottom-layer devices in the factory. Here we first introduce Ethernet, specifically industrial Ethernet. Industrial Ethernet is an industrial network protocol derived from the office automation field. 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 mainly suitable for information management and information processing systems, and it has achieved great success in the IT industry. In the fields of information integration at the factory management level and workshop monitoring level, industrial Ethernet 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 intervene at the lower device layer and widely replace existing fieldbus technologies. Schneider Electric is an active advocate and practitioner of this idea, with a batch of industrial-grade products released and practically applied. However, Ethernet cannot truly solve real-time and determinism issues, so most field layers will still prefer fieldbus technology. Due to technological limitations and conflicts of interest among manufacturers, the current situation of coexistence of multiple industrial bus technologies and continuous penetration of Ethernet technology will persist for some time. Users can choose the required solution based on technical requirements and actual conditions.

Hetronik Plug Material

The selection of materials is based on a comprehensive consideration of processability, product applicability, and strength properties; the cost of electronic connectors varies depending on material prices, ease of processing, and production efficiency; electronic connector materials mainly include insulator materials (plastic raw materials) and conductor materials (phosphor bronze, brass); common engineering plastics used in electronic connectors include: LCP, NYLON, PBT. 1) LCP: It has a small linear expansion coefficient, low injection molding shrinkage rate, very outstanding strength and elastic modulus, and excellent heat resistance, with a high load deformation temperature, some reaching above 340 degrees. LCP also has excellent chemical resistance and air tightness, so it is generally the first choice for 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 fluidity, beneficial for thin-wall molding, but severe shrinkage, 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, severe shrinkage. Due to the lower melting temperature, plastic melting phenomena may occur during wave soldering.

Hetronik 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 for data transmission: After the master module obtains bus control rights, it addresses the slave module, and data transmission occurs after confirmation from the slave module. Bus timing protocol: Timing protocols ensure synchronized operation and correct transmission for both parties involved in data transfer. 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 beginning 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 to each other.
