German telegaertner plug telegaertner model telegaertner price

telegaertner plugs are accessory products used to achieve electrical connections and are classified industrially as connectors. As industrial automation levels rise and industrial control requirements become stricter and more precise, the consumption of terminal blocks is gradually increasing. With the development of the electronics industry, the scope of use for terminal blocks is expanding, and their varieties are becoming more numerous. Besides PCB board terminals, the most widely used types include hardware terminals, screw cap terminals, spring terminals, and more. Terminal blocks are applied to facilitate wire connections; they are essentially metal strips enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires may sometimes need to be connected and sometimes disconnected; in such cases, terminals can be used to connect them and allow for disconnection at any time without the need for welding or twisting them together, which is very convenient and quick. They are also suitable for interconnecting large numbers of wires. In the power industry, there are dedicated terminal strips and terminal boxes filled with terminal blocks, including single-layer, double-layer, current, voltage, standard, and disconnectable types. A certain crimping area is required to ensure reliable contact and sufficient current carrying capacity.

telegaertner plug classification

Terminal blocks can be divided into European-style terminal block series, pluggable terminal block series, transformer terminal blocks, building wiring terminals, fence-style terminal block series, spring-style terminal block series, DIN rail terminal block series, wall-through terminal block series, and optocoupler terminal blocks. Pluggable types consist of two parts connected by plugging: one part clamps the wire and then plugs into the other part, which is soldered onto the PCB board. Based on this underlying mechanical principle, the vibration-proof design ensures long-term airtight connection and product reliability. Assembly ears can be added to both ends of the socket; these ears largely protect the contacts and prevent poor alignment, while the socket design ensures correct insertion into the housing. Sockets can also feature assembly clips and locking clips. Assembly clips provide more secure fixation to the PCB board, and locking clips can lock the housing and socket after installation. Various socket designs accommodate different insertion methods into housings, such as horizontal, vertical, or angled orientation relative to the printed circuit board, allowing selection based on customer requirements. Both metric and standard wire gauges can be selected, making this the best-selling terminal type on the market. Fence-style terminals enable safe, reliable, and effective connections, especially in high-current and high-voltage environments. Spring-style terminals are a new type utilizing spring mechanisms, widely used in global electrical and electronic engineering industries: lighting, elevator control, instruments, power supplies, chemical, and automotive power applications. DIN rail mounting adopts reliable screw connection technology, electronic fuse technology, and the latest electrical connection technology, widely used in power electronics, communications, electrical control, and power supply fields. DIN rail types use wire clamping and unique self-locking screw designs to ensure reliable and safe connections. This series features an aesthetically pleasing appearance and can be equipped with various accessories such as short-circuit bars, marking strips, and partitions. Wall-through types use screw connection technology; the insulation material is PA66 (flammability rating: UL94, V-0), and the connectors use high-quality highly conductive metal materials.

telegaertner plug features

Utilizing existing DIN rail terminal block frame screw connection technology and adding circuits composed of electronic components, optical transmission coupling is achieved. The core of automatic control requires that the control unit be reliably isolated from various sensors and actuators to avoid interference. Sanmenwan WUKG2 opto-isolation terminals effectively fulfill this function, ensuring that field signals match the low voltage required by electronic control devices. They can also serve as interface elements between peripheral equipment for process control and control, signal, and regulator devices, suitable for different voltage and power ranges. Opto-isolation terminals offer advantages such as low signal loss at the control end, high switching frequency, no mechanical contact bounce, wear-free switching, high insulation voltage, resistance to vibration, independence from position, and long service life, leading to widespread application in the field of automatic control.

telegaertner plug applications

Each bus type has its specific application areas. For example, FF and PROFIBUS-PA are suitable for process control in industries such as petroleum, chemical, pharmaceutical, and metallurgy; LonWorks, PROFIBUS-FMS, and DevieceNet are suitable for buildings, transportation, agriculture, and other fields; DeviceNet and PROFIBUS-DP are suitable for manufacturing. However, these divisions are not absolute, as each fieldbus strives to expand its application areas and penetrate each other's markets. Most fieldbuses are backed by one or several large multinational corporations and have established corresponding international organizations to expand their influence and gain more market share. For instance, PROFIBUS is mainly supported by Siemens and has established the PROFIBUS International User Organization. WorldFIP is mainly backed by Alstom and has established the WorldFIP International User Organization.
