Applications & Industries
Industrial components by real use case. Source electrical and automation components according to the system they are installed in — control cabinets, production equipment, machinery and integrated automation projects.
Industrial Sourcing Workflow
Built for engineers and purchasing teams. The site is structured around the information industrial buyers actually have: manufacturer, part number, series, technical requirement, quantity and delivery destination.
From exact part number to sourcing decision. NJ INTER supports direct model sourcing, multi-item BOM review and cross-reference requests without forcing buyers through a consumer-style shopping flow.
Part-Number Driven Manufacturer + exact model + series.
BOM Friendly Multiple line items in one request.
Cross Reference Equivalent and replacement review.
Technical Context Specifications and application requirements.
01 Identify the component Search by manufacturer, series or exact part number.
02 Review technical fit Compare specifications, application and replacement requirements.
03 Send RFQ or BOM Submit quantity, destination and required delivery date.
04 Complete sourcing review Move into quotation, availability and commercial follow-up.
Technical Resources
Engineering information before quotation. Technical notes, comparisons and application guides help buyers validate a model or replacement before sending an RFQ.
Product comparison & cross-reference resources Use technical references to compare terminal-block sizes, understand series differences and prepare a more precise sourcing request.
Visit Technical Resources → Part Number, Cross Reference & RFQ
Start with the information you already have. Use an exact manufacturer part number, upload a multi-item BOM, or request an equivalent when the original component is unavailable or discontinued.
