QM (1.78mm-.070") CONNECTORS-"MICRO 70"
General
Designed to fill the needs of high density and miniature
interconnection, the QM series are Super-Small IDC
Connection. This IDC plug uses I/O Cable <AWG # 30>
with 0.89mm (.035") spacing. This new QM connector-
design ensures RFI/EMI shielding protection. Available
in 8, 14, 26, and 32 way.
Features
(1) 1.78mm (.070") grid contact position enables high den-
sity designs.
(2) Ribbon construction of contacts provides excellent
mechanical strength.
(3) Capable group IDC termination of 0.89 mm (.035") pitch
cable <AWG No.30> to achieve labor saving in con-
nection work.
(4) The connectors can be grounded to the PCB to isolate
EMI/FRI generated from the cable and connector as
well as latched to PCB.
(5) Zinc alloy die-cast shell and Metallic shell reduce the
penetration of external EM noise.
(6) Hood type and with Lock mechanism type are available
for Cover shell. One touch lock mechanism assures
easy and quick connection.
Applications
Suitable for personal terminals, peripherals and terminals.

4. How to install Cover case
Please refer to next page.
5. Precaution for Cable End Finish
The cover case of QM series is made of zinc alloy die-cast which is effective for EMI shielding
protection and the outside of cover case is coated with silver to provide excellent connection.
The shield structure for this QM series comprises 5 parts as per figure below, Therfore, I/O End
Finish Treatment is essential for EMI shielding protection.
Grounding to PCB can be accomplished through the connection of plates provided on both
sides of plug and receptacle.

QM40-※※P/QM40-※※PA (Solder Plug Connectors)
The solder connectors have been developed for use with thinner cables than the convention-
al specified cables.
The connectors are basically the same as the QM30. Design the harness by considering the
following.
1. Solder wires quickly (15W • 3sec) because the connector housings are made of PET resin
(thermoplastic).
2. Be sure to make the diameter cables to the dimensions specified on Page 177.
