Product Introduction: The Weidmuller 0302860000 is a pluggable printed circuit board (PCB) terminal block connector. It is designed to provide a reliable and removable electrical interface between a PCB and external wiring, featuring a compact footprint, secure screw clamping, and compatibility with standard DIN rails for easy integration into industrial enclosures.
The Weidmuller 0302860000 is a component from Weidmuller's extensive range of connection technology products. It serves a fundamental purpose in electrical and electronic systems: to create a secure, organized, and serviceable point of connection between the fixed circuitry of a printed circuit board (PCB) and the field wiring that connects to sensors, actuators, power supplies, or other external devices. Unlike soldered connections, this terminal block is pluggable. It consists of a base (header) that is soldered directly onto the PCB and a removable terminal block (plug) that attaches to it. This design allows for the external wires to be connected and disconnected without disturbing the PCB solder joints, facilitating easier installation, maintenance, and component replacement in control panels, drives, and other industrial electronics.
The design of the 0302860000 incorporates several features that address common challenges in industrial wiring. Its pluggable interface is the core benefit, enabling modularity and simplifying panel assembly and service. The connection to the wire is typically made via a cage clamp or screw clamp mechanism, which provides a gas-tight, vibration-resistant connection suitable for a wide range of conductor types, including fine-stranded wires with ferrules. The housing is made from high-quality, flame-retardant thermoplastics (e.g., PA6.6) that offer excellent mechanical strength and chemical resistance. Furthermore, the terminal block is designed for DIN rail mounting (typically TS35), allowing it to be snapped securely onto a standard rail within an enclosure, ensuring stable positioning and efficient use of panel space.
The performance and compatibility of the Weidmuller 0302860000 are defined by the following technical parameters:

The versatility of the 0302860000 makes it a staple in numerous electrical and electronic applications that require reliable, modular connections.
Used extensively to connect field device wiring (sensors, buttons) to the I/O modules of Programmable Logic Controllers (PLCs), providing a clean and serviceable interface.
Employed on the PCBs of switch-mode power supplies, variable frequency drives (VFDs), and servo drives to provide terminal points for AC input, DC output, and control signal wiring.
Found in devices like signal conditioners, data loggers, and process indicators where external sensor or communication cables need to be connected to internal electronics.
Utilized in control units within rail vehicles and infrastructure due to their vibration resistance and reliable connection under demanding environmental conditions.
Proper installation ensures optimal performance. The PCB header is first soldered onto the circuit board, aligning with the designated footprint. The pluggable terminal block is then snapped onto a DIN rail in the desired location within the enclosure. Field wires are prepared (often with ferrules for stranded wires) and inserted into the terminal clamps, which are tightened to the specified torque to ensure a secure connection without damaging the conductor. Finally, the terminal block is plugged onto the PCB header. This two-step process separates PCB assembly from field wiring, streamlining production and allowing for pre-wired panels. For maintenance, the terminal block can be unplugged for testing or replacement without requiring desoldering from the PCB.
The Weidmuller 0302860000 pluggable PCB terminal block exemplifies the innovation in modern electrical connection technology. By combining a reliable plug-in interface with robust screw clamping and DIN rail mounting, it solves key challenges of modularity, serviceability, and space efficiency in panel building. Its technical specifications ensure safe and dependable performance across a wide spectrum of industrial voltages, currents, and environmental conditions. As a critical component in control panels, power electronics, and automation devices, it provides the essential link between the static world of circuit boards and the dynamic world of field wiring. Choosing the 0302860000 is a decision for enhanced design flexibility, simplified maintenance, and long-term connection reliability in any industrial application.
