German dehner plug dehner model dehner price

dehner plug is a conductive device that bridges two conductors in a circuit, allowing current or signals to flow from one conductor to another. An electronic connector is an electromechanical system that provides a separable interface for connecting two subsystems. Simply put, components used to complete electrical connections between circuits or electronic devices are called connectors, serving as a bridge between them. In addition to meeting general performance requirements, it is particularly important that electrical connectors achieve good contact, reliable operation, and easy maintenance. Whether they operate reliably directly affects the normal operation of aircraft circuits and involves the safety of the entire host. Therefore, host circuits have very strict requirements for the quality and reliability of electrical connectors. It is precisely because of the high quality and high reliability of electrical connectors that they are also widely used in military systems such as aviation, aerospace, and national defense. Common classification methods for electrical connectors include appearance, structure, and application.

1) Developing towards miniaturization, high density, and high-speed transmission; 2) Developing towards high performance and high-frequency technology; 3) There is also a large market demand for high-voltage and high-current connectors; 4) Connectors are also developing towards anti-interference technology, modular technology, and lead-free technology. As the rate of traditional parallel synchronous digital signals approaches its limit, high-speed serial transmission is a good solution. This makes Low-Voltage Differential Signaling (LVDS) the main electrical level standard for next-generation high-speed signals. The selection of high-speed connectors has also become a major issue to be resolved for high-rate signal interconnection. Several key technologies adopted in the development of high-speed connectors include: 1) Differential signaling, noise-free signaling, and ground plane technologies used to reduce crosstalk; 2) Adjusting connector leads to change delay differences caused by unequal physical distances between connector inputs and outputs; 3) To achieve maximum transmission efficiency, the characteristic impedance of the connector should match the characteristic impedance of the transmission circuit.

Field control equipment has communication functions, facilitating the construction of factory bottom-layer control networks. Open and consistent communication standards give the system openness and interoperability between devices. Standardization of function blocks and structures ensures interchangeability between devices with the same functions. Distributing control functions to the field gives the control system structure a high degree of decentralization. Fieldbus brings automatic control equipment and systems into the realm of information networks, opening up broader fields for their application; multiple control devices can be connected on a pair of twisted pairs, helping to save installation costs; reducing maintenance expenses; improving system reliability; and providing users with more flexibility in system integration.

dehner plug main parameters

1) Rated voltage: Also known as operating voltage, it mainly depends on the insulating materials used in the connector and the spacing between contact pairs. Certain components or devices may fail to perform their intended functions when operated below their rated voltage. The rated voltage of a connector should effectively be understood as the maximum operating voltage recommended by the manufacturer. In principle, connectors can operate normally at voltages below the rated voltage. The author recommends selecting the rated voltage reasonably based on the connector's dielectric strength (withstand voltage) specifications, according to the application environment and safety level requirements. This means that with the same dielectric strength specification, different maximum operating voltages can be applied depending on the specific application environment and safety requirements, which aligns better with actual usage conditions. 2) Rated current: Also known as operating current. Similar to rated voltage, connectors generally operate normally when the current is below the rated current. During the connector design process, thermal design is employed to meet rated current requirements, because when current flows through the contact pair, heat is generated due to conductor resistance and contact resistance. When the temperature rise exceeds a certain limit, it will damage the connector's insulation and cause softening of the contact pair surface plating, leading to failures. Therefore, limiting the rated current effectively means limiting the internal temperature rise of the connector to not exceed the designed specified value. A key consideration during selection is that for multi-core connectors, the rated current must be derated. This is particularly important in high-current applications; for example, for 3.5mm contact pairs, the rated current is generally specified as 50A, but for 5 cores, it must be derated by 33%, meaning the rated current per core is only 38A. The greater the number of cores, the larger the derating magnitude. 3) Contact resistance: Contact resistance refers to the resistance generated at the contact interface between two conductive contacts. Two issues should be noted during selection: First, the contact resistance specification of a connector actually refers to the contact pair resistance, which includes both the contact resistance and the conductor resistance of the contact pair. Since conductor resistance is typically small, the contact pair resistance is often referred to as contact resistance in many technical specifications. Second, in circuits carrying small signals, attention must be paid to the conditions under which the specified contact resistance is tested, because oxide layers, oil stains, or other contaminants on the contact surfaces can create film resistance. As the film thickness increases, the resistance rises rapidly, making the film layer a poor conductor. However, the film layer can undergo mechanical breakdown under high contact pressure, or electrical breakdown under high voltage and high current. For some compact connectors designed with relatively low contact pressure, where the application involves only mA and mV levels, the film resistance is not easily broken down, which may affect signal transmission. One of the contact resistance test methods in GB5095 "Basic Test Procedures and Measurement Methods for Electromechanical Components Used in Electrical Equipment," namely the "Contact Resistance - Millivolt Method," specifies that to prevent breakdown of the insulating film on the contacts, the open-circuit electromotive force (DC or AC peak) of the test circuit shall not exceed 20mV, and the DC or AC test current shall not exceed 100mA. 4) Shielding: In modern electrical and electronic equipment, the increasing density of components and their interrelated functions impose strict limits on electromagnetic interference. Therefore, connectors are often enclosed in metal housings to prevent internal electromagnetic radiation or interference from external electromagnetic fields. At low frequencies, only magnetic materials provide significant shielding against magnetic fields. In such cases, there are specific requirements for the electrical continuity of the metal housing, which relates to the housing contact resistance.
