German SAUER DANFOSS plug, SAUER DANFOSS model, SAUER DANFOSS price

SAUER DANFOSS plugs are accessory products used to achieve electrical connections and are categorized industrially as connectors. As industrial automation levels rise and industrial control requirements become increasingly strict and precise, the consumption of terminal blocks is gradually increasing. With the development of the electronics industry, the scope of use for terminal blocks is expanding, and their varieties are becoming more diverse. Besides PCB board terminals, the most widely used types include hardware terminals, nut terminals, spring terminals, and more. Terminal blocks are applied to facilitate wire connections; they are essentially metal strips enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires may need to be connected at times and disconnected at others; in such cases, terminals can be used to connect them, allowing for disconnection at any time without the need for welding or twisting together, which is very convenient and fast. They are also suitable for interconnecting large numbers of wires. In the power industry, there are dedicated terminal strips and terminal boxes filled with terminal blocks, including single-layer, double-layer, current, voltage, standard, and disconnectable types. A certain crimping area is required to ensure reliable contact and sufficient current carrying capacity.

SAUER DANFOSS plug classification

Terminal blocks can be classified into European-style terminal block series, pluggable terminal block series, transformer terminal blocks, building wiring terminals, barrier-type terminal block series, spring-type terminal block series, DIN rail terminal block series, feed-through terminal block series, and optocoupler terminal blocks. Pluggable types consist of two parts that connect via plug-in: one part clamps the wire and then plugs into the other part, which is soldered onto the PCB board. Based on this mechanical principle, the anti-vibration design ensures long-term airtight connection and product reliability. Assembly ears can be added to both ends of the socket; these ears largely protect the contacts and prevent poor alignment, while the socket design ensures correct insertion into the housing. Sockets can also feature assembly clips and locking clips. Assembly clips provide more secure fixation to the PCB board, and locking clips can lock the housing and socket after installation. Various socket designs accommodate different insertion methods for housings, such as horizontal, vertical, or angled orientation relative to the printed circuit board, allowing selection based on customer requirements. Both metric and standard wire gauges can be selected, making this the best-selling terminal type on the market. Barrier-type terminals enable safe, reliable, and effective connections, especially in high-current and high-voltage environments. Spring-type terminals are a new type utilizing spring mechanisms, widely used in global electrical and electronic engineering industries: lighting, elevator control, instrumentation, power supplies, chemical, and automotive power applications. DIN rail mounting adopts reliable screw connection technology, electronic fuse technology, and the latest electrical connection technology, widely used in power electronics, communications, electrical control, and power supply fields. DIN rail types use wire clamping and unique self-locking screw designs to ensure reliable and safe connections. This series features an aesthetically pleasing appearance and can be equipped with various accessories such as short-circuit links, marking strips, and partitions. Feed-through types use screw connection technology, with insulation material made of PA66 (flammability rating: UL94, V-0), and connectors made of high-quality highly conductive metal materials.

SAUER DANFOSS plug advantages

1) The dual-bus structure oriented toward memory offers higher information transmission efficiency, which is its main advantage. However, conflicts still occur when both the CPU and I/O interfaces access memory. 2) The CPU connects to high-speed local memory and local I/O interfaces via a high-transmission-rate local bus, while slower global memory and global I/O interfaces connect to a slower global bus, thereby balancing high-speed and slow-speed devices so they do not interfere with each other. 3) Simplifies hardware design. It facilitates modular structural design; microcomputer designs oriented toward the bus only require manufacturing cpu plugins, memory plugins, and I/O plugins according to these specifications. Connecting them to the bus allows operation without considering detailed bus operations. 4) Simplifies system structure. The entire system structure is clear. There are fewer connections, and backplane wiring can be printed. 5) Good system expandability. First, scale expansion merely requires inserting more plugins of the same type. Second, functional expansion only requires designing new plugins according to bus standards, and the insertion positions for plugins often have no strict limitations. 6) Good system update performance. Because cpu, memory, I/O interfaces, etc., are connected to the bus according to bus protocols, as long as the bus design is appropriate, new plugins can be designed at any time following advancements in processor chips and other related chips. Inserting new plugins into the backplane updates the system, generally without requiring changes to other plugins or backplane wiring. 7) Facilitates fault diagnosis and maintenance. Motherboard test cards can conveniently locate faulty areas and identify bus types.

SAUER DANFOSS plug applications

Each bus type has its specific application areas. For instance, FF and PROFIBUS-PA are suitable for process control in industries such as petroleum, chemical, pharmaceutical, and metallurgy; LonWorks, PROFIBUS-FMS, and DevieceNet are suitable for buildings, transportation, agriculture, and other fields; DeviceNet and PROFIBUS-DP are suitable for the manufacturing industry. However, these divisions are not absolute, as each fieldbus strives to expand its application domain and penetrate each other's markets. Most fieldbuses are backed by one or several large multinational corporations that have established corresponding international organizations to expand their influence and gain greater market share. For example, PROFIBUS is mainly supported by Siemens Company, which established the PROFIBUS International User Organization. WorldFIP is mainly backed by Alstom Company, which established the WorldFIP International User Organization.
