Coaxial Contact Data
Installation Data
1. Use basic tool M22520/5-01 with Y-211 die
(#995-0002-249) for crimping.
2. Use extraction tool No. CET-C8. An insertion tool
is not requried (See Note 5).
3. Center contact, rear insulator, crimp ring, support
bushing (not applicable to RG58/RG142 coax-
ials), seal sleeve, front insulator, shell and ferrule
are shipped unassembled in a common container.
Without Seal
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.

SEAL 1
5. To extract coaxial, push back seal sleeve and
support bushing. Slip cable into extraction tool
Push tool into insert until contacts coaxial retain-
ing shoulder. Grip both cable and tool with one
hand and pull coaxial rearward out of insert
cavity.
6. To facilitate extraction of contacts, the length of
free cable adjacent to the rear surface of the
connector should not be less than 2.000 (50.80).

FERRULE
BRAID
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 untill it is tight against shoulder on ferrrule. 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.

FRONT INSULATOR
COAXIAL SHELL
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 chamber on crimp sleeve. Press sleeve firmly into coaxial shell and
crimp.
C. After assembled coaxial is inserted into connector, push suppurt bushing into grommet until shoulder rests on tubular
extension. Then pull sealing sleeve forward until it is snug on grommet.

CONTACT
REAR INSULATOR
A. Carefully push inner conductor through rear insulator.
B. While holding rear insulator firmly against ferrule, trim conductor to .156 (3.96)/.146 (3.91) dimension.
C. Place contact over conductor and solder.
Dimensions are shown in inches (millimeters).
