QR/P4 SERIES
Small Rectangular Multi-electrode Solderless Connectors for Racks and Panels
General
Dec.1.2018 Copyright 2018 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
QR/P4 Series is a series of small connectors for rack
and panel application. This is a smaller-size version of
the QR/P and QR/P1 Series, whose rectangular multi-
electrode plug in connectors for racks and panels have
been well received in the market.
Six models with different numbers of contacts are
available: 8, 12, 16, 24 32 and 40. Wires are connected
to the connectors without solder for easier connection
and higher reliability.
Features
(1) The pins can be smoothly inserted into the recepta-
cle, and give stable contact pressure bcause of their
point contact with the receptacle blades.Furthermore,
they have a larger allowance for the variation of con-
nection length - a characteristic of plug-in connec-
tions.
(2) The connector size has been made smaller by sepa-
rating the terminals for signals from those for voltage
supply.
(3) The pitch of the signal terminals inside the housing is
2.54mm. Tow pairs of diametrically opposed elec-
trodes (four electrodes in total) on the two sides are
arranged with a pitch of 5.08mm so that they can
withstand high voltage, and can be used for power
supply. In addition, a nonflammable material (UL94V-
0) is used as the insulating housing of the connectors.
Guide pins and the housing body are molded as one
piece to achieve a smaller connector size.
Since the connectors are mounted on racks or pan-
els with stepped screws, connection and disconnec-
tion can be done easily.
The contact for female terminals in the housing is
deeper than the fitting surface of the housing which
conforms to the finger test (UL Standard 1950).
The connectors of this series have passed UL, CSA
and TÜV standard.
