Control Panels & Industrial Wiring
Prepare conductor ends and assemble terminal connections for control cabinets and machinery. Match ferrule size, terminal geometry and crimp profile to the wire and the receiving terminal block.
Automotive Wiring & Harness Assembly
Review ring terminals, splices and connector leads for vehicle wiring projects. Confirm conductor size, vibration exposure, moisture conditions and the approved connection system for the intended application.
Equipment & Appliance Assembly
Explore terminals and wiring accessories for internal equipment connections. Check blade dimensions, mating interfaces, routing space and insulation requirements against the approved drawing or sample.
Terminal & Connector Selection Information
Wire ranges, material, voltage, temperature and applicable documentation vary by model. Request the selected product’s specification sheet rather than applying one rating to the entire range.

Select Terminals & Connectors in Six Practical Steps
Step 1: Define the Connection
Specify the connection type, mating component and operating environment. Include the equipment drawing or approved sample reference.
Step 2: Identify the Conductor
Provide conductor size, material, strand construction, insulation diameter and the number of conductors to be terminated.
Step 3: Check the Geometry
Confirm stud diameter, blade width, barrel size, insertion depth and available assembly space for your chosen terminal.
Step 4: Match the Tooling
Use the specified terminal-wire-tool combination. Confirm strip length, crimp profile and any heat shrink instructions for that model.
Step 5: Review Inspection Criteria
Inspect and test the completed connection using the criteria required by your project. An illustrative image is not an installation instruction.
Step 6: Approve Order Details
Confirm part numbers, quantities, documents, samples, packaging and delivery terms before releasing a production order.

Terminals & Connectors: Frequently Asked Questions
How do I choose the right terminal?
Start with conductor size and construction, mating dimensions and the application environment. Confirm the selected part number, specification sheet and approved installation instructions.
What is the difference between vinyl and nylon insulation?
These product families use different insulation constructions. Compare the exact model’s material, dimensions and working conditions rather than assuming all models share the same performance.
Are heat shrink terminals waterproof?
Do not assume a waterproof rating for every heat shrink terminal. Check sleeve construction, assembly instructions and any documented sealing or environmental qualification for the selected model.
How do I select a wire ferrule?
Match conductor cross-section and strand construction to the ferrule, then check insertion length, collar dimensions and the receiving terminal block. Confirm the required crimp tool and profile.
Can one crimp tool handle all terminals?
No. Tool and die compatibility depends on the terminal geometry, conductor and required crimp profile. Use the specified combination and inspection criteria.
Can TONFUL supply OEM packaging?
Discuss product mix, bag quantities, inner boxes, outer cartons and proposed artwork with your enquiry. Availability, MOQ and approved packaging details are confirmed in the quotation.
Which documents should I request?
Ask for the selected model’s drawing, specification sheet, assembly instructions and applicable documentation. Confirm exact model coverage rather than assuming every product shares one approval.
