General
QR/P8 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. Three different elec-
trode numbers are available: 8,12 and 20. Wires are
connected to the connectors without solder for easier
connection and higher reliability.
Features
(1) The connector of this series is about 20% smaller in
length than of the QR/P4 Series with the same num-
ber of electrodes.
(2) Two pairs of electrodes on two sides have a pitch of
5.3 mm at the reinforcement of the housing guide
pins, making the connector size smaller and
enabling the connector to withstand high voltages.
These electrodes therefore can be used for power
supply. The terminals for signals have a pitch of 2
mm
(3) Wires of AWG #20 - 28 can be connected with the
two pairs of terminals on the two sides, while wires
of AWG #24 - 28 can be connectord with the termi-
nals for signals.
(4) The pins give stable contact pressure because of
their point contact with the receptacle blades, and
have a larger allowance for the variation of connec-
tion length - a characteristic of plug-in connectors.
(5) The guide pins and the housing body are moulded
as one piece to achieve a smaller connector size.
(6) Since the connectors are mounted on racks or pan-
els with stepped screws, connection and disconnec-
tion can be done easily.
(7) The connectors of this series have passed UL, CSA
and TÜV standards.
Application
PPC, Transmission and reception equipment, Data Communication, Vending Machine, Measuring Instruments,
Automatic Equipment, Switchboards, etc.
