Weidmüller offers a wide range of PCB (Printed Circuit Board) connectors designed to facilitate electrical connections between various electronic components and systems in industrial applications. Their PCB connectors are known for their reliability, versatility, and durability, making them suitable for demanding environments in automation, power distribution, and communication systems. Key Features of Weidmüller PCB Connectors: 1. Wide Range of Connector Types: Weidmüller offers several types of PCB connectors to meet different application needs. Some of the common types include: Pin Headers: These are often used to connect components on a PCB to external devices or other circuit boards. They typically come with male pins that can be plugged into female headers or sockets. Receptacle Connectors: These connectors are used in combination with pin headers to make secure electrical connections. Screw Terminal Connectors: Allow for secure wire-to-board connections. The wires are inserted into a screw-clamp mechanism that ensures a solid connection. Spring Clamp Connectors: These allow for fast and tool-free wire connections. The spring clamp mechanism provides a reliable connection. Wire-to-Board Connectors: These connectors are designed to connect external wires directly to a PCB, providing a secure interface between the board and external devices. 2. Various Pitch Sizes: Weidmüller PCB connectors are available in various pitch sizes, which refer to the distance between pins or contacts. Common pitch sizes for Weidmüller connectors include: 2.54 mm (0.1 inch): Common for general-purpose applications. 5.0 mm: Often used for higher current applications. 7.5 mm and 10 mm: Used for heavy-duty applications requiring larger conductors. Smaller and larger pitch sizes are also available to suit specific design requirements. 3. Durability and Long Lifespan: Weidmüller PCB connectors are built to withstand harsh industrial conditions. They are designed for high durability, with features such as gold or tin plating to reduce corrosion and ensure long-term electrical performance. These connectors are typically rated for thousands of mating cycles (i.e., how many times the connectors can be plugged and unplugged without degrading the performance). 4. High Current and Voltage Ratings: Weidmüller PCB connectors are designed to handle different current and voltage requirements, from low-power signal connections to high-power electrical systems. Current ratings can range from a few amps to higher currents for industrial machinery and equipment. For example, some connectors can handle up to 20A per contact, while others are rated for much lower currents, such as 1-2A. 5. Materials and Construction: Contact Materials: The contacts in Weidmüller PCB connectors are typically made from copper alloys with gold, tin, or nickel plating to ensure reliable conductivity and prevent oxidation. Housing Materials: The housings of these connectors are generally made of high-quality plastics (e.g., polyamide (PA)) that are resistant to heat, chemicals, and mechanical stress. Some designs feature UL 94-V0-rated plastics for fire resistance. 6. Customization and Modularity: Weidmüller offers customizable PCB connectors, allowing users to select from different types of contacts (e.g., male, female), locking mechanisms, and mounting options. Modular designs allow easy customization of connector sizes, allowing users to scale up or down depending on the number of required contacts. 7. Mounting Options: Through-hole Mounting: The connectors are designed to be soldered into holes on the PCB. This is the most common type of mounting for connectors in industrial applications, as it provides strong mechanical stability. Surface Mount (SMT): Some connectors are designed for surface mount technology, where the connector is directly mounted on the surface of the PCB. This is used in high-density applications where minimizing the board\'s footprint is critical. 8. Protection Features: Weidmüller PCB connectors often include additional locking mechanisms or latches to prevent accidental disconnection or loosening of the connection. These features are particularly important in industrial or vibration-prone environments. 9. Tool-free Solutions: Some Weidmüller connectors, especially spring-clamp connectors, allow for tool-free wire insertion. This simplifies the assembly process and reduces labor costs in applications that require frequent or rapid connections. 10. Application Flexibility: Signal and Data Connections: These connectors are frequently used in signal and data transfer applications in industries like automation, automotive, telecommunications, and robotics. Power Distribution: Some PCB connectors are designed to handle higher power and can be used in applications requiring power distribution, such as power supplies and electric vehicles.
