Unique-Bargains KF2EDGK 2-Pin 3.5mm PCB Screw Terminal Block Connector 20Pcs

SKU CH-1R2Z-TRNQ3

Pack of 20 two-pin 3.5 mm pitch PCB screw terminal blocks rated 300 V for secure wire-to-board connections

  • 20 connectors per pack simplify stocking for multiple projects
  • 5 mm pitch fits standard PCB layouts
  • 300 V AC rating supports mains-level signals
  • Screw terminals allow quick wiring without soldering
  • Compact 8 mm × 12 mm × 15 mm footprint saves board space

Compact Screw Terminals for Prototyping

This pack supplies twenty two-position PCB screw terminal blocks with a 3.5mm pitch and a 300V AC rating. Each green and silver unit measures 8mm by 12mm by 15mm and combines a plastic housing with metal contacts. The connectors suit breadboard layouts, sensor wiring and low-voltage power distribution in hobby or repair work. Their screw-down clamps accept solid or stranded wire without soldering.

Ready-to-Use Connector Pack

The twenty-piece quantity lets you populate multiple boards or keep spares for field repairs without reordering. Pre-stripped wires insert directly into the rising-cage clamps, so connections can be made or changed with a small screwdriver. The 3.5mm spacing matches standard 0.14inch perfboard grids, avoiding the need for adapter boards or custom footprints. Total pack weight is 29g.

Verify Pitch and Voltage Before Buying

Confirm that your PCB layout uses a 3.5mm pin spacing and that the circuit voltage stays within the 300V AC rating. The 8mm by 12mm footprint must fit your board outline and enclosure clearance. These terminals are not suited for high-current mains wiring beyond the rated value or for boards that require a different pin count or pitch.

Questions about this item

How often will the screw terminals on these 3.5mm pitch connectors need re-tightening?

The screw terminals are designed for repeated installation and detachment, so re-tightening is only needed if vibration loosens them over time.

What is the voltage ceiling for continuous operation of the 300V rated terminal blocks?

The connectors are rated for AC 300V, so sustained loads should stay at or below that voltage.

How much heat do the 20 connectors generate when carrying current all day?

The plastic and metal construction handles normal current without noticeable heating; no active cooling is required.
