German radium plug radium model radium price

radium plug is the public communication backbone for transmitting information between various functional components of a computer. It is a transmission bundle composed of wires. According to the types of information transmitted by the computer, the computer bus can be divided into data bus, address bus, and control bus, which are used to transmit data, data addresses, and control signals, respectively. The bus is an internal structure; it is the common channel for cpu, memory, input, and output devices to transmit information. Various components of the host are connected via the bus, and external devices are connected to the bus through corresponding interface circuits, thereby forming the computer hardware system. In a computer system, the public path for transmitting information between components is called the bus. Microcomputers use a bus structure to connect various functional components.

radium plug principle

The bus is a shared data transmission device. Although multiple devices can be connected to the bus, typically only one pair of devices participates in data transmission at any given time. According to the form of information transmission, buses can be divided into parallel buses and serial buses. A parallel bus transmits n bits of binary information simultaneously using n transmission lines. Its characteristics include high transmission speed, but the system structure is more complex; it is used for connections between components within a computer system. A serial bus shares a single transmission line for multi-bit binary information, with bits transmitted sequentially over time. Its characteristics include a simple structure, but slower transmission speed. The bus must have clear specifications: Bus timing protocols, meaning that certain timing rules must be followed when transmitting information on the bus, such as synchronous bus timing, asynchronous bus timing, and semi-synchronous bus timing. Physical characteristics of the bus, including electrical characteristics of signals, power, and addresses, as well as mechanical characteristics of wiring and connectors. Bus bandwidth, which is the maximum transmission rate achievable by the bus, with the unit being MB/S.

radium plug features

Utilizing existing DIN-rail terminal block frame screw connection technology, and adding circuits composed of electronic components, optoelectronic transmission coupling is achieved. The core of automatic control requires that the control unit be reliably isolated from various sensors and actuators to avoid interference. Sanmenwan WUKG2 opto-isolated terminals can effectively perform this function, ensuring that field signals match the low voltage required by electronic control devices. They can also serve as interface elements between peripheral equipment for process control and control, signal, and regulator devices, and are suitable for different voltage and power ranges. Opto-isolated terminals offer advantages such as low signal loss at the control end, high switching frequency, no mechanical contact bounce, wear-free switching, high insulation voltage, resistance to vibration, independence from position, and long service life, making them widely used in the field of automatic control.

radium plug safety parameters

1) Insulation resistance: Insulation resistance refers to the resistance value presented by leakage current generated on or within the surface of the insulating part when voltage is applied to the insulating part of the connector. It is mainly affected by factors such as insulation material, temperature, humidity, and contamination. The insulation resistance values provided in connector samples are generally indicator values under standard atmospheric conditions; under certain environmental conditions, insulation resistance values may decrease to varying degrees. Additionally, pay attention to the test voltage value for insulation resistance. According to insulation resistance (MΩ) = voltage applied to the insulator (V) / leakage current (μA), applying different voltages yields different results. In connector tests, the applied voltages generally have three levels: 10V, 100V, and 500V. 2) Rated voltage: Dielectric strength is the critical voltage that the mutually insulated parts of contact pairs, or between insulated parts and ground, can withstand for a specified time without breakdown, exceeding the rated voltage. It is mainly affected by contact pair spacing, creepage distance, geometric shape, insulator material, ambient temperature and humidity, and atmospheric pressure. 3) Mechanical life: The mechanical life of a connector refers to its mating/unmating cycle life, typically specified as 500 to 1000 cycles. When this specified mechanical life is reached, indicators such as contact resistance, insulation resistance, and dielectric strength of the connector should not exceed specified values. Strictly speaking, mechanical life is related to time; using 500 cycles over 10 years versus using 500 cycles over 1 years clearly presents different scenarios. First, select the number of contact pairs based on circuit requirements, while considering the connector's volume and total separation force. A larger number of contact pairs naturally results in a larger volume and relatively greater total separation force. In cases with high reliability requirements where volume permits, two contact pairs can be connected in parallel to improve connection reliability. In connector plugs and sockets, pins (male contacts) and sockets (female contacts) are generally interchangeable in assembly. In actual use, selection can be made based on the live status at both ends of the plug and socket. For example, if the socket needs to remain live, choose a socket equipped with female contacts, because the live contacts are embedded in the insulator, making them less accessible to human touch and thus relatively safer. Mainly consider the electrical continuity of contact pairs during vibration, shock, and collision under specified frequency and acceleration conditions. Contact pairs may experience instantaneous open circuits under such dynamic stress. Specified instantaneous interruption times generally include 1μs, 10μs, 100μs, 1ms, and 10ms. Note how to judge instantaneous interruption faults in contact pairs. Currently, it is considered that a fault in a closed contact pair (contact) is determined when the voltage drop across its ends exceeds 50% of the power source electromotive force. That is, there are two conditions for judging instantaneous interruption: duration and voltage drop, both of which are indispensable. Connectors generally consist of plugs and sockets, where the plug is also called a free-end connector, and the socket is also called a fixed connector. Circuit connection and disconnection are achieved through the mating and unmating of plugs and sockets, resulting in various connection methods for plugs and sockets. For circular connectors, the main methods are threaded coupling, bayonet coupling, and push-pull (ball-lock) coupling. Among these, threaded coupling is the most common, offering advantages such as simple processing technology, low manufacturing cost, and wide applicability, but it has a slower connection speed and is not suitable for occasions requiring frequent mating/unmating and rapid connection. Bayonet coupling has a faster connection speed due to the longer lead of its three bayonet slots, but its manufacturing is more complex and the cost is higher. Push-pull (ball-lock) coupling is the fastest among the three connection methods; it does not require rotational motion, achieving connection, separation, and locking through linear motion only. As it belongs to the straight push-pull connection method, it is only suitable for connectors with low total separation force. It is generally more common in small connectors.
