AOSI is a reliable partner for OEM wiring components. Their screw terminals are CE-certified and always arrive on time, which is critical for our project deadlines.
We tested samples from 4 suppliers, and AOSI’s screw terminal blocks were clearly the most robust and easy to install. The clamping force is excellent.
The screw terminals worked great in our solar inverter boxes. AOSI supported us with datasheets, quick quotes, and even custom color coding.
Great quality screw terminal blocks – no wire slippage and very solid build. We’ve used them in our industrial control panels for over a year with zero issues.
For high-current power wiring, screw-type terminal blocks offer low contact resistance and heat-resistant performance. They are a trusted choice in power converters, inverters, and main distribution units.
Used in HVAC control boards and intelligent building systems, screw terminals simplify field wiring while ensuring safe, long-term connectivity under varying temperature and humidity conditions.
Heavy-duty machines rely on secure wiring to prevent downtime. Screw terminal blocks are preferred for their firm connection and ability to handle shock and mechanical stress in complex equipment setups.
In trains and transportation control systems, screw terminal blocks maintain connection integrity despite constant vibration. Their high insulation strength supports safety-critical applications.
A screw terminal block is an electrical connector that joins wires using a tightening screw to create a firm electrical connection.
To wire a screw terminal block correctly, follow these steps:
Yes. We offer branding (logo engraving), custom housing colors, special packaging, and even customized screw types or pitch sizes for high-volume OEM orders. We work closely with your engineering team to match your exact design and regulatory needs.
To select the correct screw terminal block, consider the following:
✅ Current rating & voltage: Match your application’s electrical demands.
✅ Wire size range: Ensure the terminal accepts your wire gauge (e.g., 0.5–35mm²).
✅ Mounting type: PCB-mount, DIN rail–mount, or panel-mount?
✅ Environmental conditions: Exposure to heat, dust, vibration, etc.
✅ Certifications needed: CE, UL, RoHS for compliance.
Still unsure? Contact our engineers with your application scenario—we’ll recommend the best-fit model.
