KF301 2-Pin Screw Terminal Block Connector, 5.08mm Pitch

Soldering a wire directly to a PCB works fine for a permanent connection, but any wire that might need disconnecting for maintenance, testing, or field service is better served by a proper terminal block - the KF301 gives exactly that, a 2-pin screw terminal connector that mounts through-hole onto a PCB while letting wires be clamped in and released with a simple screwdriver rather than needing a soldering iron every time a connection changes.

Pin spacing follows the common 5.08mm standard, matching a widely-used terminal block footprint that's easy to design into a custom PCB layout. Electrical rating covers 220V AC at 10A, genuine headroom for power-distribution connections on a custom board rather than being limited to low-current signal wiring. Wire gauge compatibility spans 24 to 16 AWG, covering typical hookup and power wire sizes used in hobby and small commercial electronics.

Construction uses tin-plated brass for the pin header (soldering onto the PCB) and nickel-plated brass for the actual wire-clamping contacts, both platings chosen specifically for good solderability and long-term corrosion resistance at their respective connection points. The housing is PBT plastic rated UL94-0 for heat resistance, a meaningful safety margin for a connector carrying mains-adjacent current and voltage.

Builders designing a custom PCB that needs a field-serviceable wire connection point - a power input, a motor output, any connection that might reasonably need disconnecting without resoldering - will find the KF301 a well-proven, standard terminal block connector for exactly that purpose.
