Overview
TONFUL Electric MDFN nylon fully insulated male spade terminals combine a tin-plated brass contact with a translucent nylon cover. Compare three color-coded models for 0.5–6 mm² conductors, then match the mating contact and crimp-tool requirements. The flat male spade mates with a compatible female receptacle. The insulating cover surrounds the contact and wire-crimp area; the mating opening and wire entry remain accessible.
Features
- Contact interface: The flat male spade mates with a compatible female receptacle.
- Translucent nylon: allows visual inspection of wire insertion and the contact area.
- Color-coded selection: red, blue and yellow identify the catalog wire-size groups.
- Crimp termination: choose tooling and conductor dimensions for the selected model.
- Disconnectable connection: supports compatible serviceable wiring connections.

Selection Guide
Select the conductor section and color-coded model, then verify the male blade dimensions against the mating connector. Compare insertion clearance, wire-entry diameter and crimp-tool compatibility. Inspect the finished crimp and provide any additional protection required by the assembly.
Applications
Suitable enquiry examples include appliance wiring, equipment controls, automotive harness servicing and industrial maintenance with compatible quick-disconnect interfaces. Confirm the terminal, enclosure and environmental requirements for the actual installation; the nylon cover does not establish a waterproof connection.
Ordering Information
Send the full MDFN reference, conductor size, mating-contact drawing, quantity and intended application. Catalog pack quantities are listed by model; confirm retail pack size, bulk packaging, labeling and delivery terms in the quotation.
