German cis plug cis model cis price

cis 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 application scope of terminal blocks is expanding, and their varieties are becoming more numerous. Besides PCB board terminals, the most widely used types include hardware terminals, nut 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; terminals allow them to be connected and disconnected at any time without welding or twisting them together, which is convenient and fast. 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.

cis plug classification

Terminal blocks can be categorized into European-style terminal block series, pluggable terminal block series, transformer terminal blocks, building wiring terminals, barrier-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 that connect via plug-in: one part clamps the wire and then plugs into the other part, which is soldered onto the PCB board. The mechanical principle at the bottom and the anti-vibration design ensure 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 ensuring the socket inserts correctly into the housing. Sockets can also feature assembly latches and locking latches. Assembly latches provide more secure mounting to the PCB board, and locking latches secure the housing and socket after installation. Various socket designs accommodate different insertion methods into housings, such as horizontal, vertical, or angled orientation 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. Barrier-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 aesthetic design and supports various accessories such as short-circuit links, identification 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.

cis plug material

1) The material of the female or male terminal shall be copper alloy, or 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, or non-plated but 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 crimped and separated from the terminal strip, then in this case, the edge where the terminal connects to the terminal strip does not need to be plated. The standard terminals used in temperature and thermal cycling tests shall be tin-plated sheet or corrosion-resistant steel, according to the Rockwell 30T hardness standard, with a hardness of 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 standard, the hardness of standard terminals made of brass is 62 ± 7.

cis 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. 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 that have established corresponding international organizations to expand their influence and gain market share. For example, 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.
