Versatile 2-Pin Screw Terminal Blocks for Reliable PCB Connections

Versatile 2-Pin Screw Terminal Blocks for Reliable PCB Connections

 

In electronic system design, secure and flexible wiring solutions form the backbone of reliable circuitry. The 2 Pin Screw Terminal Block Connector Vertical Type Green delivers professional-grade connectivity for demanding applications across industries. Engineered with nickel-plated brass contacts and UL94V-0 rated PA66 housing, these 30A-rated terminal blocks combine industrial durability with user-friendly screw clamping - perfect for prototyping or production where vibration resistance and maintenance access matter equally.

 

Why Screw Terminal Blocks Remain Essential

While push-in connectors gain popularity, screw terminals maintain critical advantages:

- Superior mechanical grip (0.1Nm torque specification)

- Field-serviceable connections without special tools

- Visual verification of proper wire seating

- Wider temperature tolerance (-40°C to +105°C)

 

Our vertical-mount solution enhances these benefits with:

✔ Color-coded green housing for quick identification

✔ Three-tiered deck options for space optimization

✔ Through-hole PCB mounting for mechanical stability
