Overview
The QR/P18 Series of miniature rack/panel connectors
is designed for the complete segmentation of the
structure of the external holder/terminal units of the
well-received QR/P Series of plug-in rectangular rack/
panel connectors; furthermore, the subsequent
insertion of the harnessed terminal unit affords a more
efficient harness mounting task. These connectors are
configured with 12, 18, or 24 pos.(IDC) in the signal
line, and 4 pos.(crimp) in the power line.

Features
1. Completely separated structure of the
external holder/terminal unit
In order to improve the harness procedures, the
connectors are designed for the complete
segmentation of the external holder and the signal/
power supply unit, and inserting the harnessed
contacts aims to improve the workability of the power
supply/signal line harness as well as the mounting to
the set.

2. Signal unit
The signal unit uses the highly reliable insulation
displacement connection method. (The wire is AWG
#26 and the insulation outter diameter is 0.88 mm.)
The insulation displacement procedure can now be
used by attaching a special applicator to a
commercially available automatic insulation
displacement machine, or a manual press tool can
also be selected.
3. Power supply
The power supply terminals permit the use of a
crimp harness using wire of AWG#16 to 18 (and
insulation outside diameter of 2.1 to 2.2 mm), and
can accommodate a maximum of 12 A.
4. Sequential mating structure
Two sequential contacts in the signal male unit and
one sequential contact in the power supply female unit
are provided for safety operation.
5. Panel installation
Installation to a panel uses a single-action method
on the anchored side and a floating screw structure
on the floating side which permits smooth insertion
and disconnection without forcing.
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.
