Why NITAI

More Manufacturing Capability. Less Sourcing Complexity.

NITAI brings connector manufacturing, cable assembly, terminal blocks, SMT module production and engineering support closer together — giving buyers a clearer path from component to finished product.

01
Connector → Finished Cable Assembly

Finished Cable Assemblies, Built In-House.

M8 / M12 / M16 connector assembly, cable soldering, overmolding and electrical testing can stay in one production flow.

Terminal Blocks

Manufactured by NITAI, not simply sourced.

Spring, screw, pluggable, PCB and barrier terminal blocks, with selected UL / VDE certified series.

Interface Modules

Terminal blocks + SMT, built into modules.

Our component manufacturing base extends into interface, distribution and control-cabinet module production.

Fewer HandoffsLess risk between component, cable and module stages.
Faster ValidationEngineering, samples and production stay closely connected.
Better ConsistencyCritical parts and assembly are easier to control across batches.
01
Connector → Finished Cable Assembly

One flow from connector head to finished cable assembly.

For M8 / M12 / M16 programs, NITAI can handle connector assembly, cable soldering, overmolding and electrical testing in one production flow — reducing handoffs and helping buyers move faster from sample approval to repeat production.

Terminal Block Manufacturing

We make the core component instead of only sourcing it.

Spring, screw, pluggable, PCB and barrier terminal blocks are part of our own manufacturing base. That gives customers better continuity on the component that sits behind many cabinet and PCB wiring projects.

03
SMT + Interface Module Production

Our terminal-block capability continues onto the PCB.

Because we combine terminal-block manufacturing with SMT and assembly capability, NITAI is better positioned for D-SUB, RJ45, relay, PLC and power-distribution modules built for real control-cabinet use.
