SMA Straight Connectors, Captive Contact, Crimp Type for Braided Cable

1. Strip cable to dimensions shown. Do not nick outer or inner conductors. Tin inner conductor.

2. Place shrink tubing, crimp ferrule and retaining nut on cable. Flare the cable outer conductor as

shown.

3. Insert cable dielectric into rear body until it bottoms firmly against insulator as shown.

4. Place a 0,38 (.015) dia x 2,50

± 0,51 (.100 ± .020) long solder wire into solder hole of the center

contact. Heat center contact and push it over cable inner conductor until it bottoms against

insulator as shown. Remove excess solder if necessary.

5. Insert rear body into front body. Engage threads of retaining nut to front body and hand tighten

retaining nut. Hold front body firmly with a 7,93 (.312) hex. torque wrench and torque it to1,13-1,69

Nm (10-15 in. lbs.). by turning retaining nut only.

6. Slide crimp ferrule over flared portion of cable outer conductor. Crimp outer sleeve in place as

shown. Push cable firmly toward connector when crimping. Trim and remove any excess outer
