A254
2mm Pitch Connector for Discrete Wire Connection(Product approved by UL CSA Standard)
DF3 Series
s
Features
Correspond to Board Design in Wide Variation
q
ID Socket
(1) Low profile design with the mounting height of 6.8mm
(2) Achieves the multi-harness by the full automatic ID machine in combination with the DF11 series ID
type.
(DF11 series represents the 2mm pitch single-row product.Please refer to page A266 to A277.)
q
Crimp Socket
(1) Low profile design with mounting height 7.5mm.
(Please refer to the application pattern figure on page A256 for details.)
(2) Provide the contact crimping area with the sufficient space, and secures the stable crimping
operation.
q
Receptacle
(1) The board can be connected horizontally or vertically in combination with the straight header with the
right angle header.
(2) For horizontal connection, the board to board size is the low profile of 6.6mm.
(Please refer to the application pattern on page A256 for details.)
(3) Compatibility with the in-line plug allows the receptacle to set the board side to the receptacle and
the cable side to the plug in the board to cable connection.
q
Pin Header
(1) The board pre-fixed kink is treated with the post pin.
(2) The style employs a scoop-proof and sturborn box type.
(3) The type corresponding to SMT is avilable, using the heat-proof resin.
This SMT header is equipped with the metal tab to prevent peeling in the solder joint area.
q
In-line Plug
(1) The crimping in-line plug consits of two types, one type, which has pursued after space merits, and
the other employs the panel lock type, which can be fixed to the panel.
(2) The in-line adapter is available to insert and in-line the ID socket from both sides.
