German ZoeLLNER plug, ZoeLLNER model, ZoeLLNER price

ZoeLLNER plug is a connector used to connect serial and parallel cables to a data bus. The naming format for data bus connectors is DB-x, where x represents the number of wires inside the connector. Each wire is connected to a pin in the connector, but in many cases, not all pins are assigned a function. Data bus connectors are defined by various EIA/TIA standards. It is a type of connector used to connect serial and parallel cables to a data bus. DB connectors are named in the DB-x format, where x represents the number of (wires) inside the connector. Each wire is connected to a pin in the connector, but in many cases, not all pins are assigned a function. DB connectors have 9, 15, 25, 37, and 50 pin sizes. DB connectors define the physical structure of the connector, not the purpose of each wire. For example, DB-9 has 9 pins and is used to connect a mouse. DB-25 has 25 pins and is used to connect a printer.

ZoeLLNER Plug Introduction

As automation technology has evolved from standalone machine control to Factory Automation FA and further to system automation, the factory automation information network can be divided into the following three-layer structure: factory management level, workshop monitoring level, and field device level. Fieldbus is the communication network between devices at the factory floor level. Here we first introduce Ethernet, specifically Industrial Ethernet. Industrial Ethernet is an industrial network protocol derived from the office automation domain; by convention, it mainly refers to the IEEE 802.3 protocol. If the TCP/IP protocol suite is further adopted, it is denoted as "Ethernet + TCP/IP". Its technical characteristics are primarily suitable for information management and information processing systems, and it has achieved significant success in the IT industry. In the field of information integration at the factory management level and workshop monitoring level, Industrial Ethernet already has many successful cases, and there are also many applications at the device layer where real-time performance is not strictly required. Due to the wide variety of fieldbuses and inconsistent standards, many people hope that Ethernet technology can penetrate the lower device layers and widely replace existing fieldbus technologies. Schneider Electric is an active advocate and practitioner of this idea, with a range of industrial-grade products already available and in practical application. However, since Ethernet cannot truly resolve real-time and determinism issues, most field layers will still prefer fieldbus technology. Due to technological limitations and conflicts of interest among various manufacturers, the current situation, characterized by the coexistence of multiple industrial bus technologies and the continuous penetration of Ethernet technology, will persist for some time. Users can select the required solution based on technical requirements and actual conditions.

ZoeLLNER Plug Classification

Industrial bus networks can be categorized into three types: 485 network, HART network, and FieldBus fieldbus network. 485 Network: RS485/MODBUS is a popular industrial networking method, characterized by simple and convenient implementation, and there are particularly many instruments supporting RS485. Instrument manufacturers have also turned to support RS485/MODBUS for a simple reason: RS485 conversion interfaces are not only inexpensive but also come in a wide variety. At least in the low-end market, RS485/MODBUS will remain the primary industrial networking method. HART Network: HART is a transitional bus standard proposed by Emerson, mainly characterized by superimposing digital signals on a 4-20 mA current signal. However, this protocol is not truly open; one must join its foundation to obtain the protocol, which requires a certain fee. HART technology is mainly monopolized by several large foreign companies. In recent years, domestic companies have also been working on it, but they have not yet reached the level of foreign companies. Many smart instruments come with [HART round card] and support HART communication functions. However, from a domestic perspective, this part of the functionality has not been truly used for device networking and monitoring; at most, handheld configurators are used to set parameters. In the long run, due to reasons such as low HART communication speed and difficult networking, the application of HART instruments will show a downward trend. FieldBus Fieldbus Network: Fieldbus is one of the hot technologies in the automation field today, hailed as the computer LAN of the automation field. Its emergence marks the beginning of a new era in automation control technology. Fieldbus is a digital, serial, multi-station communication network connecting field instruments with control devices in the control room. Its key hallmark is the ability to support bidirectional, multi-node, bus-style fully digital communication. Fieldbus technology has become a hotspot in the international development of automation and instrumentation. Its emergence has brought revolutionary changes to traditional control system structures, further advancing automatic control systems towards "intelligence, digitization, informatization, networking, and decentralization," forming a new type of network-communication-based fully distributed control system—the Fieldbus Control System FCS (Fieldbus Control System). However, fieldbus has not yet formed a truly unified standard. Multiple standards such as ProfiBus, CANbus, and CC-Link coexist, each with its own niche. When unification will occur is uncertain. There are relatively few types of instruments supporting fieldbus, limited choices, higher prices, and smaller usage volumes.

ZoeLLNER 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, the insulation resistance value will 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 mutual insulation parts between contact pairs or between insulation parts and ground can withstand within a specified time without breakdown, which is higher than 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 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 is obviously different from using 500 cycles over 1 years. First, select the number of contact pairs based on circuit needs, 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 and permissible volume, 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 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 be constantly 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 under vibration, shock, and collision at specified frequencies and accelerations. Contact pairs may experience instantaneous disconnection under such dynamic stress conditions. 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 the closed contact pair (contact) can be determined when the voltage drop across its two ends exceeds 50% of the power source electromotive force. That is, there are two conditions for judging whether an instantaneous interruption has occurred: 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 separation 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 them, threaded coupling is the most common, offering advantages such as simple processing technology, low manufacturing cost, and wide applicability, but the connection speed is slow, making it unsuitable for occasions requiring frequent mating and quick connections. 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 coupling is the fastest among the three connection methods; it does not require rotational motion, only linear motion to achieve connection, separation, and locking. Since it belongs to the straight push-pull connection method, it is only suitable for connectors with small total separation force. It is generally more common in small connectors.
