3.96 mm Pitch Miniature Connectors for Internal Power Supplies (UL,C-UL and TÜV Listed)
DF7 Series
Complete Locking Function
Completely enclosed locking system
Full barrier between adjacent contacts. Prevention of Incorrect Connections
sFeatures
1. Complete Locking Function
Reliable interior lock protects mated connectors from accidental disconnection.
2. Increased Contact Retention of Crimped Contacts and Prevention of Incomplete Insertion
Separate contact retainer increases the contact retention, assures and visually confirms the complete contact insertion.
3. Molded-in Contact Retention Tabs
Handling of terminated contacts during the assembly and termination is easier and avoids entangling of wires, since there are no protruding metal tabs.
4. Incorrect Insertion Prevention
Connectors are polarized to assure correct mating with corresponding parts.
Guide post
5.Solder Crack Prevention
Glass reinforced resin is used in the pin header bodies to prevent solder cracks caused by the heat shrinkage.
Board Eyelet mounting
6. Prevention of Incorrect Board Placement
Built-in locating posts assure correct connector placement and orientation on the board.(2-12 pos.)
7. Supports Sealing after Installation.
Sealing compound can be applied to the board installed connector for distance of 6 mm max. from the mounting surface (9 mm max. for single position).
8.Cost Effective Tooling
The same crimping tools are used to terminate socket and pin contacts.
9. Prevention of Short Circuits between Adjacent Contacts
Each contact is completely surrounded by the insulator housing, electrically isolating it from adjacent contacts.
One pos. type can also be mounted to boards that have eyelets.
