German MULTI CONTACT plug, MULTI CONTACT model, MULTI CONTACT price

MULTI CONTACT plug terminal blocks, as a type of connector, are important components in the electrical industry, playing an irreplaceable and significant role. Since engineering technicians start troubleshooting by checking interfaces, i.e., terminals, the design of terminal blocks is particularly important. Terminal blocks can be classified into: European-style terminal block series, plug-in terminal block series, transformer terminal blocks, building wiring terminals, fence-type terminal blocks, spring-type terminal blocks, DIN rail terminal blocks, wall-through terminal blocks, and optocoupler terminal blocks. The plastic insulation materials and conductive parts of terminal blocks directly affect their quality, determining the insulation performance and conductivity of the terminals respectively.

MULTI CONTACT plug features

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 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 compensate for 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.

MULTI CONTACT plug material

1) The material for female or male terminals shall be copper alloy, plated copper alloy, nickel, or nickel alloy. [Exception: If the structure of the appliance or device permits, female or male terminals may be plated steel or non-plated corrosion-resistant alloy.] 2) If formed female terminals or trimmed male terminals appear in the form of terminal strips, when the terminal strip is continuously fed into the processing tool, the terminals are curled and separated from the strip; in this case, the edge where the terminal connects to the strip does not require plating. The standard terminals used in temperature and thermal cycling tests shall be tin-plated steel or corrosion-resistant steel, with a hardness of Rockwell 30T hardness 68 ± 5. Exception: If the female terminal is only suitable for connecting male terminals made of copper alloy, then standard terminals made of C26000 copper alloy shall be used for testing. 2.3 According to the Rockwell 30T hardness standard, the hardness of standard brass terminals is 62 ± 7.

MULTI CONTACT plug usage precautions

Fieldbus is gradually being promoted in industrial sites. Many devices not only have traditional instrument functions but also possess fieldbus capabilities. In DCS, fieldbus is widely used. The following issues should be noted when using fieldbus: 1) Communication distance. Fieldbus communication distance generally has certain requirements. For example, PROFIBUS/DP at a rate of 12Mbps, using standard cable, can reach 200m; if using a rate of 187.5kbps, it can reach 1 000m. Communication distance has two meanings: first, the distance achievable between two nodes without repeaters; generally, distance is inversely proportional to communication rate; second, the distance between the two farthest nodes in the entire network. Manufacturers' descriptions of this are often unclear. In actual use, the scope of the entire network must be considered. Electromagnetic signals take time to propagate through cables. Especially in some high-speed fieldbuses, if the distance is increased, some communication parameters must be modified; 2) Cable selection. The site environment determines the fieldbus communication speed and medium. Generally, fieldbus uses electrical signals to transmit data, inevitably affected by the surrounding electromagnetic environment during transmission. Most fieldbuses use shielded twisted pair cables. It must be noted that different types of fieldbuses may require different shielded twisted pair cables. Fieldbus developers generally specify a special cable, and the specified rate and transmission distance can only be achieved under correct usage of this cable. In extremely harsh electromagnetic conditions, optical fiber is a reasonable choice; otherwise, local interference may affect the operation of the entire fieldbus network; 3) Isolation. Generally, fieldbus electrical signals are electrically isolated from the device internals. Fieldbus cables are distributed throughout the workshop. If high voltage intrudes, it will damage the bus transceivers of all devices on the segment. Without isolation, high voltage signals will continue to damage other internal circuits of the device, leading to serious consequences; 4) Shielding. The outer layer of the shielded cable used in fieldbus must be grounded at one point. If high-frequency interference is severe, multi-point capacitive grounding can be used. Multi-point direct grounding is not allowed to avoid ground loop currents; 5) Connectors. Fieldbus generally does not have strict regulations on connectors, but improper handling can affect system communication. For example, fieldbus generally uses a bus-type daisy chain connection. When connecting each device, attention must be paid to how to insert and remove devices without affecting existing communication, which places certain requirements on connectors; 6) Termination matching. Fieldbus signals, like all electromagnetic wave signals, exhibit reflection phenomena. Resistive matching should be used at both ends of each bus segment. The first function is to absorb reflections, and the second is to achieve correct voltage levels at both ends of the bus to ensure communication. Therefore, fieldbus technology is the intersection and integration of control, computer, and communication technologies. Its emergence and rapid development reflect the control field's requirements for cost reduction, improved reliability, enhanced maintainability, and intelligent data acquisition.
