Crimp
SDN
CONNECTOR
Board-in Crimp style connectors
Features ––––––––––––––––––––––––
• Slim, low-profile design
The connector has a 3.96mm (.156") pitch that allows the
connection of a large-capacity (7A) circuit, yet it has a slim,
low-profile design, with a mounting height of 7.0mm (.276")
and width of 6.2mm (.244").

• Easy and secure contact mounting
The housing and contact are
secured by the housing lance
and the contact lance which
make use of the contact spring.
The contact is easily inserted
into the housing with little force,
and is locked securely.

The SDN connector is a 3.96mm (.156")
pitch board-in crimp style connector
capable of connecting a wide variety of
circuits including signal and power supply
circuits. The connector features a slim,
low-profile design. In addition, it has an
exclusive lance construction to reduce
insertion force, thus substantially
improving the working efficiency in
mounting the contact.
circuit board has a wider area to be soldered. Solderability of
the contact is thus improved when mounted onto a printed
circuit board.
• Polarizing boss
Connectors with or without polarizing boss are available. A
boss on the bottom of the housing prevents the connector from
being mounted on the printed circuit board in reversed polarity.

Note:
1. Tolerances are non-cumulative: ±0.05mm(±.002") for all centers. For connectors with 5 or more circuits the hole dimensions will differ from the above values.
Contact JST for details.
2. Hole dimensions differ according to the kind of PC board and piercing method. The dimensions above should serve as a guideline.
