MRE Series plugs and receptacles are the
accepted standard for rectangular-shaped,
miniature, internal-type connectors. They
embody all of the features expected of true
miniaturization: maximum utility of space,
extremely lightweight and unusually high
working voltage and current ratings. Their
long life and trouble-free service continue to
make them highly popular for use in aircraft,
instrumentation and portable equipment.
The MRE and MRA series share the same
hoods, hardware and accessories.

TERMINATION TYPES
Solder Cup
.048 diameter solder cup is the standard
termination for cable and panel mounting
applications. It will accept up to #20 AWG
stranded wire.
Dip Solder
For mounting on printed circuit boards, .025
diameter straight dip solder terminations (for
Pin Contacts and Socket Contacts) are
available. Consult the Sales Department for
available lengths.
GUIDE SOCKETS
3 Types of Guide Sockets are Available
Guide
Socket
Code Letter
Application
The “G” type socket is the standard guide supplied. It
has good physical strength and may be used electrically
in a low current circuit or as a contact for ground leads.
Actual
Size Photo
G*
G Type
For General Use
Phosphor
K*
The “K” guide socket is an excellent electrical conductor.
Its extra spring-tension provides a high normal force
uniformily distributed along the surface of the engaged
pilot guide, thus minimizing electrical resistance.
The multivolt drop across extreme ends of the engaged
pilot and socket guide is 10 mv. at 20 amps.
The high physical strength of the “N” guide socket allows
a greater degree of forcible tightening against a mounting
surface than is permitted by the other guide sockets. This
feature is particularly desirable for mounting connectors
which will be subject to severe vibration in service. “N”
guides are not to be used electrically.

* For passivated stainless steel add SS suffix
PHYSICAL DATA
HOW TO ORDER: To obtain “K” or “N”
guides in place of the standard “G” type,
substitute the desired socket style code
letter (“K” or “N”) for “G” in both the Plug
and Receptacle Code Numbers.
