We’ve been sourcing spring terminal blocks from AOSI for over 2 years. The tool-free design makes our panel assembly much faster, and the quality is consistently reliable.
AOSI’s support team responded quickly and provided customized DIN rail terminal blocks for our automation equipment. Highly professional and efficient!
We needed compact terminal blocks for a tight space in our HVAC control box. AOSI delivered on time with great service and OEM flexibility.
As a distributor, I appreciate working directly with a manufacturer like AOSI. Their spring terminal block quality, pricing, and lead time meet our global buyer standards.
AOSI spring terminal blocks are trusted across a wide range of industrial applications. From control panels e PLC systems to I/O modules e OEM electrical equipment, our solutions provide reliable, space-saving, and tool-free wiring to meet the demands of modern automation and manufacturing environments.
Spring terminal blocks ensure fast, vibration-proof wiring in control panel installations. Their tool-free design speeds up assembly and improves maintenance efficiency in automation lines.
Ideal for modular systems, our terminal blocks integrate seamlessly with I/O modules, offering quick connection and compact arrangement in PLCs and signal control boxes.
Spring Terminal Blocks are perfect for compact PLC cabinets, where saving spa ce is important. They allow multiple connections in a small area, making them ideal for dense signal wiring and modular PLC system setups.
AOSI’s terminal blocks are widely used by OEM manufacturers for customized electrical systems. With various mounting options and housing styles, they simplify internal wiring across different product lines.
A spring terminal block is a screwless wire connection component that uses internal spring force to clamp wires securely. It simplifies wiring, reduces installation time, and is ideal for high-vibration industrial applications.
Our terminal blocks support 2–24 poles with design modulare. You can either order pre-assembled units or splice individual modules using our interlocking mechanism — perfect for scalable system design.
Mounting types include:
✔️ PCB soldering with 45°, 90°, or 180° orientations
✔️ Guida DIN mounting for control panels
✔️ Panel mount for enclosures
This makes our products highly adaptable for a variety of electrical system layouts.
Yes! We offer free engineering samples to qualified buyers. Just let us know the model, pitch, number of poles, and quantity you’d like to test.
We offer multiple pitch sizes: 2.5mm / 3.5mm / 5.0mm / 7.62mm / 10.16mm, supporting different voltage, current, and space requirements. Custom pitches can be developed for specialized needs.
We provide two screwless wiring options:
– Push-in type (for solid wires)
– Button-release type (for stranded wires)
Both offer easy, secure installation with excellent contact reliability.
Yes — as a trusted spring terminal block manufacturer, we support:
🔹 Logo printing (pad/laser)
🔹 Color customization
🔹 Tailored pole count / pitch
🔹 Branded packaging
Just send us your specs or drawings for evaluation.
Per gli articoli standard: 7-10 giorni lavorativi
Per le parti personalizzate/OEM: 2-4 settimane a seconda dello stampo e del volume degli ordini.
Il nostro obiettivo è supportare tempi rapidi di progettazione e produzione.
Our spring terminal blocks support 2–24 poles and offer 45° / 90° / 180° soldering orientations, with two wiring options: push-in direct or button-operated connection.
