We switched to AOSI’s modular terminals for our HVAC control systems. The installation was quick, the quality was excellent, and the delivery was right on time.
Great product for high-density wiring! These MCS blocks saved space inside our PLC enclosures and were easy to replace during upgrades.
What impressed us was the customization flexibility. AOSI helped us match color codes and labeling for our modular connection system—professional and fast.
Reliable locking mechanism and smooth mating/unmating. We use these terminal blocks in solar combiner boxes and never had any failure.
Modular MCS terminal blocks are ideal for control panels, offering quick plug-in connections that simplify assembly, testing, and future modifications. The compact design helps save space in high-density switchgear layouts.
Used in PLC wiring and signal distribution, MCS terminal blocks reduce wiring time and support modular system expansion. Their pluggable design ensures quick replacement during system maintenance.
MCS terminal blocks help simplify wiring in smart buildings, where devices like sensors, lighting modules, and control relays require modular and service-friendly wiring options.
In testing benches and lab electronics, pluggable terminal blocks allow frequent changes and upgrades of circuits without re-soldering or rewiring. Ideal for modular setups and prototyping.
MCS stands for Modular Connection System. It refers to pluggable terminal blocks that consist of a plug and a header, enabling quick, tool-free wiring and easy replacement in industrial control systems.
Yes. AOSI offers MCS terminal blocks rated up to 16A/300V depending on the pitch and model. They’re suitable for signal and low to medium power distribution.
We offer pitch sizes such as 3.5mm, 3.81mm, 5.0mm, 5.08mm, and 7.62mm, with various pole numbers from 2P to 24P. Custom pitches are available upon request.
Yes! Here’s how to request samples:
Step1. Choose the model(s) from our catalog.
Step2. Share your company name, application, and shipping address.
Step3. We’ll confirm stock and send samples via DHL or FedEx.
Step4. Standard samples are free; customized ones may incur a fee.
MCS terminal blocks are widely used in control panels, PLC systems, building automation, renewable energy, and laboratory equipment. Their modular plug-in design makes them ideal for systems that require frequent maintenance, quick wiring changes, or space-saving layouts.
The plug side connects to field wiring and can be easily detached. The header is fixed on the PCB or DIN rail and connects to the internal circuit. Together, they form a modular, pluggable connection.
Absolutely. All AOSI pluggable terminal blocks comply with CE and RoHS directives. We also support UL requests for specific OEM models.
To install MCS terminal blocks on a PCB, follow these steps:
Yes. We provide PDF datasheets, CAD drawings, and 3D STEP files for all MCS models to support your product design and PCB layout planning.
Yes. MCS terminal blocks are ideal for AI-driven control panels, such as those used in smart factories, robotics, and edge computing units. Their pluggable design allows for fast integration, module swapping, and streamlined signal wiring in dynamic AI applications.
Looking for flexible, modular wiring solutions? AOSI’s MCS terminal blocks offer tool-free plug-in connections ideal for control panels, automation systems, and smart devices.
