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.
