1. Use Crimp Tool No. DIE Y211 (995-0002-249), Tool M22520 / 5-01 (995-

0001-761).

2. Use extraction tool No. CET-C8. An insertion tool is not required.

(See Note 5).

3. Center contact, rear insulator, crimp ring, support bushing (not applicable to

RG58/RG142 coaxials), seal sleeve, front insulator, shell and ferrule are

shipped unassembled in a common container.

4. Cable Assembly Instructions:

Step 1 - If applicable, determine which portion of seal sleeve should be

used. If seal 2 is used, cut off seal 1 portion.

Step 2 - In sequence, place seal sleeve, support bushing and crimp ring

over cable jacket.

Step 3 - Trim cable per illustration.

Step 4 - Comb out braid and flare out ends to permit entry of ferrule.

Step 5 - Complete termination per illustration. (See below)

5. To extract: coaxial, push back seal sleeve and support bushing. Slip cable into ex-

traction tool. Push tool into insert until it contacts coaxial retaining shoulder. Grip

both cable and tool with one hand and pull coaxial rearward out of insert cavity.

6. To facilitate extraction of contacts and avoid splaying, the length of free cable

adjacent to the rear surface of the connector should not be less than 2.000

(50.80).

A. Carefully push inner conductor through rear insulator.

B. While holding rear insulator firmly against ferrule, trim conductor to .156

(3.96)/.146 (3.71) dimension.

C. Place contact over conductor and solder.

APPROX.

A. Push ferrule under braid as far as it will go. Trim off braid extending beyond

shoulder of ferrule, if necessary.

B. While holding ferrule in place pull crimp sleeve forward over braid until it is

tight against shoulder an ferrule. Pull firmly against face of ferrule to make

sure it is up tight.

C. Trim dielectric to the .035 (0.89)/.030 (0.76) dimension.

A. Place front insulator over contact and then push assembly into coaxial shell.

B. Place parts in jaw of crimp tool. Locate jaws at start of chamfer on crimp

sleeve. Press sleeve firmly into coaxial shell and crimp.

C. After assembled coaxial is inserted into connector, push support bushing into

grommet until shoulder rests on tubular extension. Then pull sealing sleeve

forward until it is snug on grommet.
