German Martens plug Martens model Martens price

Martens plugs are accessory products used to achieve electrical connections and are classified industrially as connectors. As the level of industrial automation increases and industrial control requirements become stricter and more precise, the consumption of terminal blocks is gradually rising. With the development of the electronics industry, the scope of use for terminal blocks is expanding, and the variety is increasing. 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 a metal strip enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires may need to be connected at times and disconnected at others; 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 fast. They are also suitable for large-scale interconnection 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.

Martens plug classification

Terminal blocks can be categorized into European-style terminal block series, pluggable terminal block series, transformer terminal blocks, building wiring terminals, barrier-type terminal block series, spring-type 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. Based on this underlying mechanical principle, the anti-vibration 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 for 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. Barrier-type terminals enable safe, reliable, and effective connections, especially in high-current and high-voltage environments. Spring-type 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 links, 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.

Martens 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 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 connect to 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 standard terminals made of C26000 copper alloy 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.

Martens plug applications

Each fieldbus 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 domain and penetrate other markets. Most fieldbuses are backed by one or several large multinational corporations that have established corresponding international organizations to expand their influence and gain greater 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.
