MRAC Series Miniature Rectangular, Removable Contacts

Removable contacts offer a substantial savings

of time, labor and a great flexibility in the choice

of circuitry. The contact is easily removed with

the hand tool depicted and then placed by

hand or with a simple insertion tool.

The MRAC Series is an important extension of the MRA line featuring a variety

of crimp and solder removable contact styles. Except for body thickness, they

are similar and interchangeable with the MRA Series.

FEATURES

■Closed Entry

Removable Socket

and Pin Contacts.

■Connector Inserts with

9 to 104 Contacts.

■Quick Crimp ... Snap in

Place!

■To remove ... insert

removal tool — “Push

Out” Contact!

solder, shielded or Wire-

Wrap termination contacts.

See 100 Series contact

section.

Contact

Identificaiton: Standard contact identifica-

tion is alphabetical except for

MRAC66 and 75 which have

numerical identification. To

order numerical identification

on MRAC 34, 50 or 104,

JACKSCREWS & JACKSOCKETS

Polarized jackscrews give the ease and

assurance of threaded positive coupling.

The actuating side consists of two turnable

screws, one male and one female, each with

knurled and slotted knobs. On the mating half

are the two fixed screws required to

complete the locking action. When mated,

the jackscrews may be locked with a safety

wire through the hole in the self-locking pin

(in the jackscrew shaft).

Note 1:When panel mounting the lock-tab half of a MRAC 34, MRAC 42 or MRAC 50 connector, flat washers

(.033 minimum thickness) should be used on the mounting screws to shim the molding away from the panel.

Note 2: Each code number indicates two units, i.e., the “MRE-VL” consists of two levers and two pivots

(unassembled*), and the “MRE-V” consists of two tabs.

Note 3: These units are supplied unassembled to facilitate handling. The pivot is easily assembled to the

lever merely by inserting the hooked end through the lever opening. It will automatically snap into proper

position. Patent #2,760,174.

parts to the plug and receptacle is quick and easy.

The unit locks automatically when the mating plug

and receptacle are engaged. Unlocking and

disengaging can be done with one hand.
