QR/P4 SERIES

Small Rectangular Multi-electrode Solderless Connectors for Racks and Panels

General

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.

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,

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.

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.

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

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
