German Novotechnik plug Novotechnik model Novotechnik price

Novotechnik plugs are accessory products used to achieve electrical connections and are categorized industrially as connectors. As the level of industrial automation increases and industrial control requirements become stricter and more precise, the consumption of terminal blocks is gradually rising. With the development of the electronics industry, the scope of use for terminal blocks is expanding, and their varieties are increasing. Besides PCB board terminals, the most widely used types include hardware terminals, screw-cap terminals, spring terminals, and so on. Terminal blocks are applied to facilitate wire connections; they are essentially a metal strip enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires may sometimes need to be connected and at other times disconnected; in such cases, terminals can be used to connect them and allow for disconnection at any time without the need for welding or twisting them together, which is very convenient and fast. Moreover, they are 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 to guarantee that sufficient current can pass through.

Novotechnik plug classification

Terminal blocks can be divided 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-mounted terminal block series, wall-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 at the bottom, 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 of the contacts. Meanwhile, this socket design ensures that the socket can be correctly inserted into the housing. Sockets can also have assembly clips and locking clips. Assembly clips provide more secure fixation to the PCB board, while locking clips can lock the housing and socket after installation. Various socket designs can accommodate different insertion methods for the housing, 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 widely used in high-current and high-voltage environments. Spring-type terminals are a new type of terminal block utilizing spring devices, widely applied in the global electrical and electronic engineering industries: lighting, elevator control, instruments, power supplies, chemical, and automotive power, among others. 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-mounted types adopt wire clamping and unique self-locking screw designs, making wire connections reliable and safe. This series of terminal blocks features an attractive appearance and can be equipped with various accessories, such as short-circuit links, identification strips, and partitions. Wall-through types adopt screw connection technology, with insulating material made of PA66 (flammability rating: UL94, V-0), and connectors made of high-quality, highly conductive metal materials.

Novotechnik 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 methods; microcomputer designs oriented toward the bus only need to manufacture cpu plugins, memory plugins, and I/O plugins according to these specifications. Connecting them to the bus allows them to operate without considering the detailed operations of the bus. 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 merely requires designing new plugins according to bus standards; the insertion positions for plugins in the machine often have no strict limits. 6) Good system update performance. Because the 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 advances in processor chips and other related chips. Inserting new plugins into the backplane updates the system, and other plugins and backplane wiring generally do not need to be changed. 7) Facilitates fault diagnosis and maintenance. Motherboard test cards can conveniently locate faulty areas and identify bus types.

Novotechnik plug applications

Each bus type largely has its own application fields. For example, 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 areas and penetrate each other's markets. Most fieldbuses are backed by one or several large multinational corporations and have established corresponding international organizations to expand their influence and gain more market share. For example, PROFIBUS is mainly supported by Siemens Company and has established the PROFIBUS International User Organization. WorldFIP is mainly backed by Alstom Company and has established the WorldFIP International User Organization.
