German MOOG plug MOOG model MOOG price

MOOG plug is an industrial data bus that has developed rapidly in recent years. It mainly addresses digital communication between intelligent instruments, controllers, actuators and other field devices on the industrial site, as well as information transfer between these field control devices and advanced control systems. Due to a series of prominent advantages such as simplicity, reliability, and cost-effectiveness, fieldbus has received high attention from many standards organizations and computer manufacturers. It is an industrial data bus and serves as the underlying data communication network in the field of automation. The emergence of fieldbus plays a very important role in industrial development and has a significant impact on national economic growth. Fieldbus is mainly applied in fields such as petroleum, chemical industry, electric power, pharmaceuticals, metallurgy, processing and manufacturing, transportation, national defense, aerospace, agriculture, and buildings.

MOOG plug introduction

Fieldbus is an open interconnected network that can interconnect with networks at the same layer or different layers, and can also achieve shared access to network databases. Fieldbus embodies the characteristics of distribution, openness, interconnection, and high reliability, which are precisely the shortcomings of DCS systems. DCS typically transmits signals one-to-one; the analog signals used have low precision and are susceptible to interference. Operators in the control room often find it difficult to adjust parameters and predict faults with analog instruments, leaving them in an 'out of control' state. Many instrument manufacturers define their own standards, resulting in poor interchangeability and relatively single-function instruments that are difficult to meet modern requirements. Furthermore, almost all control functions are located in the control station. FCS, on the other hand, adopts one-to-many bidirectional signal transmission. The digital signals used offer high precision and strong reliability, keeping equipment under remote monitoring and controllable status by operators at all times. Users can freely choose devices from different brands and types for interconnection as needed. Intelligent instruments possess rich functions such as communication, control, and computation, and control functions are distributed among various intelligent instruments. Thus, we can see the tremendous progress of FCS compared to DCS. It is precisely due to the above characteristics of FCS that it offers significant advantages from design and installation to commissioning and normal production: Firstly, since distributed front-end intelligent devices can perform more complex tasks, separate controllers and computing units are no longer required, saving on hardware investment and footprint; FCS wiring is relatively simple, and multiple devices can be connected to a single transmission line, greatly reducing installation costs; since field control devices often have self-diagnostic capabilities and can send fault information to the control room, maintenance workload is reduced; meanwhile, users have a high degree of autonomy in system integration and can flexibly select suitable products from manufacturers; the overall system reliability and accuracy are also significantly improved. All this helps users reduce installation, usage, and maintenance costs, ultimately achieving the goal of increasing profits.

MOOG plug material

1) The material for female or male terminals shall be copper alloy, or plated copper alloy, nickel, or nickel alloy. [Exception: If the structure of the electrical appliance or device permits, female or male terminals may be plated sheet metal, 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 sheet metal or corrosion-resistant steel. According to the Rockwell 30T hardness standard, 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 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 terminals made of brass shall be 62 ± 7.

MOOG plug troubleshooting

During electrical assembly, it is often found that individual crimped wires are not fully inserted into the contacts, or cannot be locked after insertion, resulting in unreliable contact. The cause is analyzed to be burrs or dirt jamming at the threads of individual mounting holes. This is particularly problematic for the last few mounting holes of a connector housing already assembled by the user; upon discovering this defect, all previously crimped wires in other holes must be removed one by one, and the connector housing replaced. In addition, improper matching between wire diameter and crimp barrel diameter, or operational errors in the crimping process, can lead to insecure crimp connections. Therefore, before shipment, the manufacturer must perform a go/no-go test on all mounting holes of sample connectors (housings), i.e., using assembly/disassembly tools to simulate inserting wires with pins or sockets to check if they can be locked. According to product technical specifications, pull-out force tests are conducted on each crimped wire. Without reliable terminal blocks, there can be no reliable system engineering. Failure and reliability are two aspects of a contradictory entity that are both opposite and interconnected. By conducting reliability screening of terminal blocks, various failure modes and mechanisms can be identified, yielding valuable lessons and eliminating potential hazards, thereby providing a scientific basis for improving design, manufacturing processes, inspection, and usage. It also serves as an important basis for revising and establishing technical specifications for terminal blocks. The ultimate goal of failure analysis is to find measures to prevent failures and achieve the transformation from failure to reliability.
