The KF301 2-Pin 5.08mm Pitch Screw Terminal Block is the most reliable way to create secure, removable wire-to-board connections. At Electrapac, we recommend these connectors for any project requiring high-current power input or sensor wiring that needs to be easily swapped or maintained.

Product Overview

The KF301 series is a standard "screw-type" terminal block designed for PCB mounting. Featuring a modular interlocking design, these blocks allow you to slide and lock multiple units together to create 4, 6, or 8-pin strips. Each pin features a rugged internal cage clamp that grips the wire tightly as you tighten the top screw, ensuring a vibration-resistant connection.

Key Features for Electrapac Customers

• Standard 5.08mm Pitch: Perfectly compatible with standard 2.54mm perf-boards and breadboards (occupying every second hole) and standard PCB layouts.

• Solder-Free Wire Connection: No need to solder wires directly to your board. Simply strip the wire, insert it into the terminal, and tighten the screw.

• Interlocking Side Rails: Features a "tongue and groove" design on the sides, allowing you to snap multiple 2-pin units together to form any length required.

• High-Quality "Pillar" Screw: The screws are made of hardened steel with a zinc plating, designed to be tightened firmly without stripping the threads.

• High Temperature Resistance: The blue PBT plastic housing is designed to withstand the heat of soldering irons during installation and high-current operation during use.

Installation Tips

To ensure the best connection for your gear from www.electrapac.com:

1. Wire Stripping: Strip approximately 5mm of insulation from your wire. For stranded wire, twisting the ends or using a ferrule will provide a more secure grip.

2. Soldering to PCB: Ensure your PCB holes are at least 1.0mm in diameter to accommodate the thick metal pins of the KF301.

3. Screw Torque: Tighten firmly, but do not over-torque. The internal cage is designed to compress the wire for maximum surface contact.
