Rack & Panel MRAC Series Miniature Rectangular, Removable Contacts 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! 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. SPECIFICATIONS Current Rating: Up to 13 amps No. of Contacts: 9, 14, 18, 20, 26, 34, 41, 42, 50, 66, 75, 104 Contacts: Must be ordered separately. Select from crimp, solder, dip solder, shielded or WireWrap termination contacts. See 100 Series contact section. Contact Identificaiton: Standard contact identification is alphabetical except for MRAC66 and 75 which have numerical identification. To order numerical identification on MRAC 34, 50 or 104, specify MNAC**P or S. MILITARY CROSS REFERENCE CATALOG NO.

Assembly of either the lever-and-pivot assembly or the lock 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. 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. Hoods shown are MRA Hoods for use with MRAC Connectors Wt. DIMENSIONS - Top Opening Fits Oz.
