A 2-pin, 5mm pitch screw terminal is a component for connecting wires to a printed circuit board (PCB) with a 5mm spacing between its two straight pins. Key features include its pitch for compatibility with standard boards, a screw-type wire clamp for a secure connection, and many models offer a slide-locking mechanism to link multiple terminals for custom lengths. These terminals are rated for specific voltages and currents (e.g., 300V at 8A), accept various wire gauges (like 26-14 AWG), and are built from materials such as ABS plastic, PBT, and brass.
Features
- Pin Pitch (5mm): The distance between the centers of the two pins is 5mm, which is a standard size that aligns with many perf boards and standard 0.1" (2.54mm) spacing.
- Screw Terminal: A screw mechanism securely clamps the wire, creating a reliable electrical connection with the PCB.
- PCB Mount (Through-Hole): The pins are designed to be inserted into holes on a
- PCB and secured with solder.
- Slide-Locking Mechanism: Many terminals feature a ridge and slot design, allowing them to interlock with adjacent terminals to create longer strips.
- Wire Gauge Compatibility: The terminal can hold wires of specific sizes, typically ranging from 26 to 14 AWG (American Wire Gauge), which is a key specification for power and signal applications.
- Rating: They are rated for a specific maximum voltage (e.g., 300V) and current (e.g., 8A or 16A), ensuring safety and performance within those limits.
- Materials: Common materials include ABS or PBT for the body, brass for the contacts, and tinned contact plating for corrosion resistance.
- Applications: These terminals are widely used in electronics, communication equipment, instruments, and various automatic control systems.
