3.3 mm Contact Pitch, Connectors for Internal Power Supplies
DF33 Series
Complete
Locking
Function
Completely
enclosed
locking system
Protection from
shorts circuits
between adjacent
Contacts
sFeatures
1. 5 A maximum current
Single row connector can carry current of 5 A with #20 AWG
conductor. Please refer to Table #1 for current ratings for multi-
position connectors using other conductor sizes.
Prevention of Incorrect Connections
qStandard
Type
(Color: natural)
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.
qR
Type
(Color: black)
4. Prevention of incorrect board placement
Built-in posts assure correct connector placement and orientation
on the board.
5. Supports encapsulation
Connectors can be encapsulated up to 10 mm without affecting
the performance.
6. Prevention of Short Circuits Between
Adjacent Contacts
Each Contact is completely surrounded by the insulator housing
electrically isolating it from adjacent contacts.
*The
photographs on the left show header (the board dip side),
the photographs on the right show the socket (cable side).
*The
guide key position is indicated in position facing
the mating surface of the header.
7. 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.
