SN-28B Small-Terminal Crimping Kit

A connector that almost fits is not a useful connector. This SN-28B crimping kit is worth considering when your electronics project calls for compatible small open-barrel terminals. The reviewed images show an orange-handled ratcheting tool, compartmented terminals and housings, plus lengths of wire. A detail image shows the stepped die and ratchet adjustment. It adds a different job to the tool drawer than wire-stripping pliers: forming a terminal around prepared wire.

Start with the connector manufacturer’s terminal and wire requirements. Similar-looking connector housings do not make their contacts interchangeable. Confirm the exact terminal series, conductor size, insulation diameter and die range for the selected option. The catalog title describes a 1,550-piece kit, but the photograph is not a counted inventory. Check the package list rather than assuming every pictured accessory is included. Keep a few spare contacts for practice and compare the result with the connector’s specified crimp shape.

Use the tool only on disconnected wiring. Its coated handles do not establish an electrical insulation rating, and this listing is not a recommendation for live mains work or safety-critical wiring. A tidy-looking crimp is not by itself proof of a reliable electrical connection; follow the connector guidance for inspection and testing. We have not measured this tool’s crimp consistency. It is best suited to a defined hobby project with known connector requirements, not a universal replacement for every crimper. The displayed price comes from the dated catalog; confirm the chosen kit, US shipping and final checkout total.
