Circular Connectors

MQR Series — Microminiature Circular Connectors

MQR stands for MICRODOT

Quick Release. This line of

circular quick disconnect

connectors has metal shells

with push-pull couplings

which provide a positive

connection for rugged

environmental use. The

MQR series is specified for

cable-to-cable and cable-

to-panel applications.

The plug connector side

contains socket contacts.

The receptacle connector

side contains pin contacts.

Because the pin contact is

“active” or “live”, the pins

require the physical protec-

tion that the receptacle side

offers. (Similar to a “protect-

ed” or “shrouded” header.)

While there is no optional

hardware for the MQR

series, the receptacles

incorporate a standard jam

nut to tighten the connector

down to the board or panel.

MQR connectors are

manufactured to the per-

formance specifications of

MIL-DTL-83513.
