Long-Life I/O Connectors
3500 Series
These miniature, shielded interface connectors were designed for use with portable terminal equipment. They are
suited to a wide range of applications including hand-held terminals and PDA equipment because of excellent
insertion/removal durability (20,000 times).
■OVERVIEW
(1) Long-life connectors have an insertion/removal life
of 20,000 cycles.
(2) The structure of the contacts is the highly reliable,
two-contact bellows type.
(3) The lock uses a snap-lock system which relieves
the stress that accompanies forceful removal,
making these connectors resistant to external
forces such as sudden pulls of the cable.
(4) Release of the lock is achieved with a simple
operation of the push buttons at the left and right
sides of the plug. A positive lock sensation is
provided by a click locking sound when the
connector engages.
(5) The miniature, lightweight design (i.e., about 2g for
a 16-conductor receptacle) makes these connectors
effective in reducing the overall size and weight of
terminal equipment.
(6) Use of a new box-bending structure for the metal
shell supports EMI protection and makes this a
tough connector.
(7) ESD protection is provided by the metal shell-not
the cover (unless it is metal plated).
(8) The board mounting system uses 0.8-mm spaced
single row SMT for easy mounting.
(9) Suitable boards can be from 0.8 to 1.6mm thick,
affording a wide selection of board thicknesses.
(10) There are two types of plug-side wiring systems,
the pressure welding type designed to save labor in
wiring, and the solder type which enables an
arbitrary selection of the type of cable.

Connector Mounting Method
1. Soldering Method
This connector and board mounting method uses soldering at the four dip locations marked A at the left and
right sides as well as the two surface mounting locations marked B at the left and right sides for a total of six
locations.
Location A represents board through holes of 1.8mm diameter and 1mm diameter, whereas
location B represents pads of 2.8 ×1.85mm width. (See the board mounting diagram.)
As illustrated in the diagram below, the opening portion of the connector is either inserted into the body of
the set or inserted into a rectangular hole of the set.
2. Soldering and Screw Fastening Method
When there is not sufficient strength with the connector opening portion at the set, the mounting holes C (as
in Figure 1) at the left and right sides of the connector are used after the solder mounting to further fix the
connector with M2 screws.
The connector can be fixed to just the board with this method (as in Figure 2); however, in consideration of
connector twisting, the most effective mounting method is to fix the connector to both the body and the
board with screws as illustrated in Figures 3 and 4.
