7.92 mm Contact Pitch, High-Current Connectors for Internal Power Supplies (UL, C-UL and TÜV Listed)

DF22 Series

■Features

1. 30 A maximum current

Single position connector can carry current of 30 A with #10 AWG

conductor. Please refer to Table #1 for current ratings for multi-

position connectors using other conductor sizes.

2. Complete Locking Function

Reliable interior lock protects mated connectors from accidental

disconnection.

3. Prevention of Incorrect Connections

To prevent incorrect connection when using multiple connectors

having the same Number of contacts, 3 product types having

different mating configurations are available.

4. Molded-in contact retention tabs

Handling of terminated contacts during the crimping is easier

and avoids entangling of wires, since there are no protruding

metal tabs.

5. Prevention of incorrect board placement

Built-in posts assure correct connector placement and

orientation on the board.

6. Supports encapsulation

Connectors can be encapsulated up to 10 mm without affecting

the performance.

7. Prevention of Short Circuits Between Adjacent Contacts

Each Contact is completely surrounded by the insulator housing

electrically isolating it from adjacent contacts.

8. Increased Retention Force of Crimped Contacts

and confirmation of complete contact insertion

Separate contact retainers are provided for applications where

extreme pull-out forces may be applied against the wire or when a

visual confirmation of the full contact insertion is required.

9. Full Line of Crimp Socket Contacts

Realizing the market needs for multitude of different applications,

Hirose has developed several variants of crimp socket contacts

and housings. Continuous development is adding different

variations. Contact your nearest Hirose Electric representative

for latest developments.

10. In-line Connections

Connectors can be ordered for in-line cable connections. In

addition, assemblies can be placed next to each other allowing
