German Leuze plug Leuze model Leuze price

Leuze 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, pluggable terminal block series, transformer terminal blocks, building wiring terminals, barrier-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 their insulation and conductivity performance respectively.

Leuze plug applications

Mainly used in lighting, communications, security, and other industries. Pluggable terminals have the widest range of applications, such as in variable frequency drives, explosion-proof equipment, CNC panels, access control controllers, sensors, PLC, instruments, power supplies, servo drives. The common requirements for pluggable terminals in these industries are: smooth insertion and extraction force, low contact resistance, and sufficient service life and fatigue resistance, which imposes higher requirements on metal spring clip materials. This requires product designers to have experience in structure and material selection. Barrier-type terminals are mainly used in: power supplies, relays (especially double-deck terminals), inverters, elevator industry (less common), and air conditioners. Requirements for this series include high torque requirements for screws during wire crimping, the distance from the screw's highest position must be greater than the maximum wire clamping range, long-position terminals must not warp or deform, and screws must have high corrosion resistance.

Leuze plug material

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

Leuze plug usage precautions

Fieldbus is gradually being promoted in industrial sites. Many devices not only have traditional instrument functions but also 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 12Mbps rate, using standard cable, can reach 200m; if using 187.5kbps rate, it can reach 1 000m. Communication distance has two meanings: first, the distance 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 entire network range must be considered. Electromagnetic signals take time to transmit through cables, especially in high-speed fieldbuses. If the distance increases, 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. Note that different types of fieldbuses may require different shielded twisted pair cables. Fieldbus developers usually specify a special cable, and the specified rate and transmission distance can only be achieved when this cable is used correctly. In extremely poor 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 interior. Fieldbus cables are distributed throughout the workshop. If high voltage intrudes, it will damage the bus transceivers of all devices in the segment. Without isolation, high voltage signals will continue to damage other internal circuits, 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 imposes 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 reducing costs, improving reliability, enhancing maintainability, and increasing the intelligence of data acquisition.
