PCB screw terminal block

The Unique-Bargains KF2EDGK is a 4-position screw terminal block with a 3.5mm pitch for printed-circuit-board wiring. Rated at 300V and 10A, it suits low-voltage power and signal connections in consumer, industrial and military electronics. Each green plastic housing measures 15mm by 12mm by 15mm and weighs 14g. The pack contains five connectors for multiple assembly points.

Sustained load behaviour

The screw-clamp mechanism maintains a gas-tight joint that resists vibration and thermal cycling during continuous operation at the rated 10A. Copper-alloy contacts limit temperature rise so the block stays within its 300V insulation class over long duty cycles. No moving springs or levers are present to fatigue under repeated heating and cooling. The plastic body retains dimensional stability across the specified operating range.

Interface practical limits

The fixed 3.5mm pitch restricts the connector to conductors that fit the 0.13inch spacing, so very thick cables cannot be terminated directly. Only solid or ferruled stranded wire up to the implicit gauge for this pitch should be used to avoid shorting between adjacent positions. The block is not polarised; orientation must be managed by the PCB layout. Five pieces per pack limits spares for larger production runs.

  • Four-position connector simplifies compact PCB wiring
  • 5 mm pitch fits dense board layouts

Questions about this item

Does the 300 V 10 A rating generate noticeable heat or noise during continuous use?

No, the connector is a passive component with no moving parts or active circuitry, so it produces no audible noise and negligible heat under its rated 300 V 10 A load.

What wire gauge and tools do I need to use these 3.5 mm pitch terminals?

You need solid or stranded wire that fits the 3.5 mm pitch openings, a small screwdriver for the screw terminals, and a PCB with matching 3.5 mm hole spacing for soldering the blocks in place.

Will these green 4-pin blocks fit the same footprint as older 5 mm pitch terminal strips I already have?

No, the 3.5 mm pitch is physically narrower than 5 mm pitch strips, so the pin spacing and PCB hole pattern are different and not interchangeable.
