KET ST741346-3 025 II Terminal: Pre-Crimp Setup FAQ
Summary: KET ST741346-3 is a small non-sealed terminal record in the 025 II series. This guide turns the manufacturer record into a practical pre-crimp question set for purchasing, quality and harness teams. It does not approve a housing, wire, applicator, crimp height or finished assembly. Those decisions still require the current controlled drawing, process specification and project authority.
What does the ST741346-3 record establish?
The KET ST741346-3 product page identifies the exact item under review. KET's published record places it in the 025 II series and describes a straight-side, pre-tin terminal made from phosphor bronze. It also marks the item as non-sealed. These fields are useful for identity control, but they should not be extended into an unverified compatibility statement.
The official record lists a 0.64 mm tab thickness, a .025 inch mating-tab width, a 1.1–1.7 insulation range, and wire references of AVSS 0.3–0.5 and CIVUS 0.35–0.5. Treat each value as a document checkpoint. Confirm units, conductor construction, insulation diameter and drawing revision before a production setup is released.
Which documents should be open before setup?
Start with the KET official ST741346-3 product record and the KET ST741346-3 2D drawing. The drawing is the stronger reference for geometry and revision control; the web record is useful for indexing series and material fields. The KET 025 II search record can help locate family documents, but a family search result is not proof that another component mates with this terminal.
Your controlled packet should also include the project bill of material, approved wire specification, applicable crimp or application specification, authorized tooling record, inspection plan and change history. If any required document is unavailable, record the gap and pause the release instead of copying a setting from a visually similar terminal.
How should wire and insulation be checked?
Wire size alone is not enough. Record the conductor standard, nominal cross-section, strand construction, insulation material and measured outside diameter. Compare them with the current manufacturer documentation and project requirements. The catalogue wire references are screening inputs; they do not by themselves establish a valid crimp for every supplier or insulation system.
Prepare a sample plan that separates conductor-crimp inspection from insulation-support inspection. The responsible process document should define strip length, bellmouth, brush position, crimp height, crimp width, pull-force method and acceptance limits where applicable. This article intentionally does not invent those settings.
Does “non-sealed” simplify the assembly decision?
No. The manufacturer record says ST741346-3 is not sealed, but that single field does not define the environmental capability of a completed connector assembly. A non-sealed terminal may be used in a housing or system with other environmental controls, yet that relationship must come from the intended connector documentation and project design.
Keep the terminal review linked to the exact cavity, housing, mating interface and retention system. Use the 025 connector series index only to organize research. Never treat a shared series label as automatic mating or substitution approval.
What should receiving and production record?
- Identity: complete manufacturer number, package label, supplier traceability and purchase reference.
- Material evidence: the applicable KET record, drawing revision and any controlled project documents.
- Wire input: conductor standard, size, strand construction, insulation material and outside diameter.
- Tooling setup: authorized machine, applicator, die set, maintenance status and setup approval record.
- Inspection result: sample identifier, measured values, visual checks, disposition and responsible approver.
These records make a later deviation investigation much faster. They also keep purchasing descriptions separate from process settings. Browse the connector terminal category for catalog discovery, or the automotive connector application index for application-oriented navigation; neither page replaces controlled engineering evidence.
Quick FAQ
Can the listed 5 A value be used as a finished-harness rating?
No. The finished circuit rating depends on the complete assembly, conductor, temperature, contact system, derating rules and project requirements.
Does pre-tin plating prove a candidate terminal is equivalent?
No. Plating is only one comparison field. Geometry, retention, wire range, tooling, material, revision and application requirements must also be verified.
Can a 025 II family part be assumed to fit any 025 cavity?
No. Use exact manufacturer drawings and the intended housing documentation; a family name is a research clue, not an interface approval.
Conclusion: release the process, not just the part number
KET ST741346-3 offers a useful identity and material record for a 025 II non-sealed terminal, but a reliable crimp setup needs a complete evidence chain. Preserve the exact part number, verify the current drawing, control the wire and tooling inputs, and document inspection results before production.
