KEFA KF128B-5.0- 5.08 2.54mm 3.5mm 5.0mm 5.08mm 7.5mm 7.62mm Screwless Terminal Block PCB Spring Terminal Block

KEFA’s KF128B-5.0 is a versatile screw and spring terminal block designed for reliable connections on printed circuit boards. This series supports multiple pitch options including 2.54 mm, 3.5 mm, 5.0 mm, 5.08 mm, 7.5 mm, and 7.62 mm to fit different board layouts and wire sizes. The clean, compact design saves space while offering solid mechanical strength for industrial, commercial, and hobby electronics.

The terminal block body is made from durable plastic that resists heat and chemicals, and the metal contacts use a corrosion resistant finish to keep electrical paths stable over time. Each position has a clear screw or spring clamp that holds stripped wire firmly, preventing loose connections that can cause noise or failures. The spring version allows quick push-in wire insertion without tools, while the screw version gives extra security for high vibration environments.

Installation is simple. The tail pins match standard PCB footprints, making soldering straightforward. You can choose single or multiple positions and use right angle or straight mounting to match your assembly needs. The blocks accept solid, stranded, and Ferruled wires within the rated size range and are marked for easy wiring and maintenance. Color coding and clear labeling reduce wiring errors and speed up repair work.

Electrical ratings and mechanical strength meet common industry needs for low to medium voltage control and signal circuits. The design supports repeated wire changes and holds up during frequent service. Safety features include secure clamping, insulation barriers between poles, and strong mounting to prevent pull-out. KEFA’s quality control processes ensure consistent parts and reliable performance in each batch.

These terminal blocks are ideal for use in control panels, power supplies, communication gear, industrial automation, lighting systems, and test equipment. They suit prototyping work as well as production runs, where a dependable connection is essential. Spare parts and different pitch options allow designers to match existing board layouts without costly redesign.

The KEFA KF128B-5.0 series gives a trustworthy, easy to use, and flexible connection solution. Its variety of pitch sizes, sturdy construction, and clear mounting options make it a practical choice for technicians and engineers who need reliable PCB terminals that last.

Ordering is easy and parts come in tape, reel, or bulk packs to suit small or large jobs. Technical data sheets are available for wiring, torque settings, and temperature limits. Backed by KEFA support, these terminal blocks help reduce downtime and simplify maintenance across projects
