Use controlled application inputs and a representative validation plan before treating an interface choice as a release decision. Contents Part 1. What mis-mating risks should the design team define? Part 2. How do mechanical keys support the interface? Part 3. Where do visual and documentation cues help? Part 4. Why should adjacent interfaces be reviewed […]

Use controlled application inputs and a representative validation plan before treating an interface choice as a release decision. Contents Part 1. What belongs in the high-voltage design input? Part 2. How should clearance be mapped? Part 3. How should creepage be mapped? Part 4. Why do materials and interfaces need separate review? Part 5. What […]

Use controlled application inputs and a representative validation plan before treating an interface choice as a release decision. Contents Part 1. What must a cable-sealing design define? Part 2. How do grommets control the cable entry? Part 3. Where does overmolding change the design review? Part 4. Why is strain relief separate from sealing? Part […]

IP67, IP68, and IP69K describe different exposure conditions, so none is a universal shorthand for “better waterproofing.” Select a waterproof connector by matching the documented rating, test setup, and complete installed interface to the real equipment environment. Contents Part 1. Begin with the complete sealed interface Part 2. Read IP67 and IP68 in context Part […]

Positive locking describes a terminal or connector system that uses a defined mechanical feature to resist unintended disengagement or contact movement. Use the controlled terminal, mating component, housing, and application requirements before making a sourcing or release decision. Contents Part 1. What does positive locking mean in a terminal system? Part 2. Which retention layers […]

Contact retention is the ability of a female terminal to remain in its intended housing position after insertion and during the specified handling or service conditions. Use the controlled terminal, mating component, housing, and application requirements before making a sourcing or release decision. Contents Part 1. What is female terminal contact retention? Part 2. Where […]
