As global demand for compact and reliable electrical connections grows,PCB terminal blockshave become an essential component in modern electronics, industrial control, and smart systems. These components provide an easy way to connect wires to printed circuit boards (PCBs), making them ideal for OEM manufacturing and automated assembly.

AtNingbo Zhongbo Photovoltaic Technology Co., Ltd., we manufacture and export a wide range of high-quality PCB terminal blocks such as theZB301,ZB300, and other customized models. If you're an importer or distributor sourcing from China, here’s what you should know before placing your order.

🧩1. What Are PCB Terminal Blocks?

PCB terminal blocks are modular electrical connectors mounted directly on a printed circuit board. They provide secure, soldered or screw-clamp connections between field wiring and internal electronics.

Zhongbo offers both:

• Screw-type PCB terminal blocks(e.g., ZB301 series)

• Spring clamp typesfor faster tool-free connections

• Multiple pitch sizes(3.5mm, 3.81mm, 5.0mm, 5.08mm)

• Vertical or right-angle orientation

📏2. Key Specifications to Consider Before Ordering

Before importing PCB terminal blocks, make sure your supplier can meet your technical and production requirements. Key parameters to review include:

• Pitch size(distance between terminals)

• Rated current and voltage

• Mounting style(vertical or horizontal)

• Wire size compatibility

• Plastic housing material (e.g., PA66)

• Flammability rating (UL94V-0 recommended)

• Certifications (UL, CE, RoHS)

At Zhongbo, we manufacture tointernational standardsand support OEM customizations—including logo printing and custom packaging.
