Screw Terminal Block Two Pin Connector Stackable

Screw Terminal Block - 2-Pin Stackable PCB Connector (Part No. BZ31)

Description
This 2-pin stackable screw terminal block (Part No. BZ31) is a compact through-hole PCB connector designed for secure wire-to-board electrical connections. Featuring a durable blue housing with top-entry screw clamps, it allows stranded or solid wires to be safely secured without soldering. Side interlocking dovetail grooves enable multiple 2-pin blocks to be connected together seamlessly to create custom multi-pin terminal strips to suit your circuit board layout.

Key Features:

• Stackable Interlocking Design: Side interlocking grooves allow multiple 2-pin blocks to be joined together to build custom length terminal strips.
• Screw Clamp Terminals: Top screw-down clamps provide firm, vibration-resistant wire retention for solid or stranded wire.
• Through-Hole PCB Mount: Standard PCB solder pins for easy through-hole board assembly and circuit prototyping.
• Compact Footprint: Space-saving profile ideal for custom electronics, PCB projects, and power distribution boards.

Technical Specifications:

• Part Number: BZ31
• Connector Type: 2-pin screw terminal block
• Mounting Type: Through-hole PCB mount
• Voltage Rating: 250V
• Terminal Count: 2 screw-down terminals per block
• Pin Length: Approx. 4 mm
• Dimensions: Approx. 10 x 10 x 12.5 mm (W x D x H)

Suggested Uses & Applications:

• Connecting power leads, sensors, speakers, and external wiring to printed circuit boards.
• DIY electronics, microcontroller projects, and custom audio crossover circuit boards.
• Creating modular power distribution rails on custom prototyping boards.

Installation & Assembly Tips:

• Modular Interlocking: Slide side interlocking grooves together before soldering onto the PCB when creating multi-pin terminal arrays.
• Wire Installation: Strip wire insulation to the appropriate length, insert the conductor into the terminal opening, and tighten the top screw securely without over-tightening.
