German DEUTSCHMANN plug, DEUTSCHMANN model, DEUTSCHMANN price

DEUTSCHMANN plugs are a standardized method for exchanging data between computer components, providing data transmission and control logic in a universal way. From another perspective, if the Mother Board is a city, then the bus is like a public bus in the city, transporting constantly operating bit back and forth along fixed routes. These lines can only transmit one bit at a time. Therefore, multiple lines must be used simultaneously to send more data. The amount of data the bus can transmit simultaneously is called the width, measured in bits; the greater the width, the better the transmission performance. The bus bandwidth (i.e., the total amount of data that can be transmitted per unit time) is: Bandwidth = Frequency × width (Bytes/sec).

DEUTSCHMANN Plug Introduction

Fieldbus technology is the intersection and integration of control, computer, and communication technologies, covering almost all continuous and discrete industrial fields, such as process automation, manufacturing automation, building automation, home automation, and so on. The development of fieldbus technology is reflected in two aspects: one is the continuous development and improvement in the low-speed fieldbus domain; the other is the development of high-speed fieldbus technology. Fieldbus products are mainly low-speed bus products, applied in domains with lower operating rates, where the performance requirements for the network are not very high. From the perspective of actual application, most fieldbuses can effectively implement process control with lower rate requirements. Therefore, in control domains with lower rate requirements, it is difficult for any single entity to unify the entire market. Since the FF Foundation has concentrated most of the world's major automation instrument manufacturers, its global influence is increasing day by day, but its marketing efforts in the Chinese market seem insufficient, and its market share is not very high. LonWorks has formed a comprehensive system of division of labor and cooperation, achieving some substantive progress domestically. In areas such as building automation, home automation, and smart communication products, LonWorks possesses unique advantages. In the discrete manufacturing and processing sector, due to the characteristics of industry applications and historical reasons, Profibus and CAN have established their own advantages in this field and possess strong competitiveness. Domestic manufacturers are relatively small in scale and have weaker R&D capabilities, relying more on support from technology suppliers. They are easily influenced by the level of support and marketing efforts provided by fieldbus technology suppliers (such as chip manufacturers) in the domestic market. Moreover, one point that cannot be ignored is the degree of support for bus devices by the upper-level computer systems selected when constructing automation management systems, such as configuration software. Some monitoring and configuration software, such as Realinfo monitoring configuration software or InTouch, provides good support for some mainstream bus devices like Lonworks, PROFIBUS, and CAN, communicating and acquiring data through DDE, OPC, or direct connection methods. This facilitates user selection, whereas some configuration software supports fewer types, thereby reducing the range of choices available to users.

DEUTSCHMANN 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, PBT. 1) LCP: Features a low coefficient of linear expansion, low injection molding shrinkage, 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 the first choice for LCP material for general connectors, especially those requiring SMT, 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 required before molding to prevent hydrolysis. General connectors, especially DIP, mostly use NYLON material, 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 occur during wave soldering.

DEUTSCHMANN Plug Selection Factors

PC communication with intelligent devices mostly relies on RS232, RS485, Ethernet, etc., mainly depending on the device interface specifications. However, RS232 and RS485 only represent the physical media layer and link layer of communication. To achieve bidirectional data access, one must write communication applications themselves, but such programs mostly do not comply with ISO/OSI specifications, can only achieve relatively single functions, are suitable for single device types, and the programs lack universality. In a device network connected by RS232 or RS485 devices, if the number of devices exceeds 2, RS485 must be used as the communication medium. For devices in an RS485 network to exchange information, it can only be achieved through relay by a "Master" device. This master device is usually PC, and only one master device is allowed in such a device network, with the rest being Slave devices. Fieldbus technology is based on the ISO/OSI model, has a complete software support system, and can solve problems such as bus control, collision detection, and link maintenance.
