German Stratus plug Stratus model Stratus price

Stratus plugs are conductive devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to another. They are widely used in various electrical circuits to connect or disconnect current or signals. This connection may be temporary and allow for easy plugging and unplugging, or it may be a permanent junction between electrical equipment or wires. Electronic connectors are devices that transmit electronic signals (analog or digital) and provide a separable interface to connect two sub-electronic systems. They are components used to complete electrical connections between circuits or electronic machines. Examples include power plugs/sockets, IC sockets, and telephone line plugs. They are widely used in the electronics industry. An electronic connector is an electromechanical system that provides a separable interface to connect two sub-electronic systems. Simply put, components used to complete electrical connections between circuits or electronic machines are called connectors, acting as a bridge between them. Connectors serve as electrical/electronic transmission links between circuits, components, and systems, ensuring stable and reliable flow of power, signals, and current, while facilitating product assembly, maintenance, and replacement.

Stratus plug structure

Electrical connectors consist of a fixed-end connector, i.e., the female contact (referred to as the socket), and a free-end connector, i.e., the male contact (referred to as the plug). The socket is fixed to the powered component via its square (or round) flange (some also use soldering), while the plug is generally connected to a cable, with the plug and socket connected via a coupling nut. Electrical connectors consist of three basic units: the shell, the insulator, and the contacts. 1) Shell: The electrical connector shell refers to the housing of the plug and socket, the coupling nut, and the rear accessories. The housing protects internal parts such as the insulator and contacts (collectively referred to as pins and sockets) from damage. Positioning key slots on the housing ensure proper alignment of the plug and socket. The coupling nut is used for connecting and separating the plug and socket. Rear accessories protect the wire-to-contact termination from damage and secure the cable. The shell also provides a certain degree of electromagnetic shielding. Shells are generally machined from aluminum alloy (machining, cold extrusion, or die casting). Steel shells are mostly used for glass-sealed and high-temperature electrical connectors. 2) Insulator: Composed of pin insulators, socket insulators, interface seals, and wire seals. It holds the pins and sockets in their designated positions and ensures electrical insulation between individual contacts and between the contacts and the shell. Sealing measures are achieved through the insulator combined with interface and wire seals to improve the environmental resistance of the electrical connector. To withstand high temperatures, low temperatures, and flame retardancy, and to ensure stable and reliable geometric dimensions, insulators are mostly molded from thermosetting plastics. Interface seals and wire seals are formed by molding silicone rubber, etc. 3) Contacts: Contacts include male and female contacts, sometimes referred to as pins and sockets. Connection methods include soldering, crimping, press-fit, and wire wrapping, used to achieve circuit connections. Pins and sockets are key components of electrical connectors, directly affecting reliability. They are mostly machined from elastic copper alloys with good conductivity, with silver or gold plating on the surface to achieve low contact resistance and corrosion resistance. Sockets generally include split-type, wire spring, crown spring, and stamped types. Structural features include: environmental resistance, bayonet (quick) connection, multiple key positions (anti-misinsertion), and crimped connection between contacts and wires (single-wire removal facilitates fault handling). The shell plus a shielding ring ensures 360° electromagnetic interference shielding capability.

Stratus plug classification

Industrial bus networks can be categorized into three types: 485 networks, HART networks, and FieldBus fieldbus networks. 485 network: RS485/MODBUS is a popular industrial networking method, characterized by simple and convenient implementation, and there are many instruments supporting RS485. Instrument manufacturers have also turned to support RS485/MODBUS for the simple reason that RS485 conversion interfaces are not only inexpensive but also diverse. At least in the low-end market, RS485/MODBUS will remain the primary industrial networking method. HART network: HART is a transitional bus standard proposed by Emerson, mainly characterized by superimposing digital signals on a 4-20 mA current signal. However, this protocol is not truly open; one must join its foundation to obtain the protocol, which requires a fee. HART technology is mainly monopolized by a few large foreign companies. In recent years, domestic companies have also engaged in this, but have not yet reached the level of foreign companies. Many smart instruments come with [HART round card] and support HART communication functions. However, from a domestic perspective, this function is not truly used for device networking and monitoring; at most, handheld configurators are used for parameter setting. In the long run, due to low HART communication rates and difficult networking, the application of HART instruments will show a downward trend. FieldBus Fieldbus network: Fieldbus is one of the hot technologies in the automation field today, hailed as the computer LAN of the automation domain. Its emergence marks the beginning of a new era in automation control technology. Fieldbus is a digital, serial, multi-station communication network connecting field instruments with control devices in the control room. Its key hallmark is the support for bidirectional, multi-node, bus-style fully digital communication. Fieldbus technology has become an international hotspot in the development of automation and instrumentation. Its emergence has brought revolutionary changes to traditional control system structures, further advancing automated control systems toward "intelligence, digitization, informatization, networking, and decentralization," forming a new type of networked communication fully distributed control system—the Fieldbus Control System FCS (Fieldbus Control System). However, fieldbus has not yet formed a truly unified standard. Multiple standards such as ProfiBus, CANbus, and CC-Link coexist, each with its own niche. Unification is nowhere in sight. There are relatively few types of instruments supporting fieldbus, limited choices, higher prices, and smaller usage volumes.

Stratus plug assembly

The northbridge chip on the motherboard is responsible for connecting components with the highest data throughput, such as memory and graphics cards, and links to the southbridge chip. The CPU connects to the northbridge chip via the front-side bus (FSB), and thereby exchanges data with memory and graphics cards through the northbridge chip. The front-side bus is the primary channel for the CPU to exchange data with external components; therefore, the data transfer capability of the front-side bus has a significant impact on overall computer performance. Without a sufficiently fast front-side bus, even a powerful CPU cannot significantly improve overall computer speed. The maximum data transfer bandwidth depends on the width of all simultaneously transferred data and the transfer frequency, i.e., data bandwidth = (bus frequency × data bit width) ÷ 8. The front-side bus frequencies achievable on a PC include 266MHz, 333MHz, 400MHz, 533MHz, and 800MHz. A higher front-side bus frequency indicates greater data transfer capability between the CPU and the northbridge chip, allowing the CPU to perform more effectively. CPU technology develops rapidly, with computing speeds increasing quickly. A sufficiently large front-side bus ensures adequate data supply to the CPU, whereas a lower front-side bus cannot provide enough data to the CPU, thus limiting the performance of the CPU and becoming a system bottleneck.
