contact size, the MRA and MRE Series share
the same hoods, hardware and accessories.
The MRA Series offers compact, lightweight
and self-aligning plugs and receptacles with
unusually high current and voltage ratings for
their size. Performance tests show them to
well exceed military standards. Except for
Right angle, dip solder, pin or socket contacts
are available. Consult factory.

TERMINATION TYPES
Solder Cup
Dip Solder
For pin and socket contacts, .070 diameter
solder cup is the standard termination for
cable and panel mount applications. Wire
accommodation: up to #16 AWG stranded.
For pin and socket contacts, .030 diameter
dip solder terminations, straight or right angle
for mounting to printed circuit board or for use
with flexible cable.
GUIDE SOCKETS
3 Types of Guide Sockets are Available

Code Letter
Application
Actual
Size Photo
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.
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.
K Type For High
Electrical Conductivity
Beryllium Copper
Standard Guide
Pin mates with all types
Brass
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.

Mounting Note: Connectors MRA 9, MRA 14, MRA 20 and MRA41 use guides or fixed jacks for mounting in a
hood or on a panel. Connectors MRA 34, MRA 42, MRA 50, MRA 66, MRA 75 use four #4 machine screws,
and MRA 104 uses four #6 machine screws for mounting in a hood or on a panel. Guides are not recom-
mended for use with MRA 104.
Note: When ordering hoods, hardware and connectors separately for use with JTD Monojacks, connec-
tors must be ordered as follows:
Pin connector = MRA34P8, MRA42P8, etc.
Socket connector = MRA34S8, MRA42S8, etc.
The number “8” indicates special housing for use with the JTD Monojack hardware
(available on sizes 34, 42, 50, 66, 75 and 104).
