Hundreds of other connector designs are available for special requirements such as high power, swept 90 bends, environmental sealing, low intermod characteristics, and special plating.

Superior Cable Technology

Shielding Options: Silver or tin plated copper wire, bare copper or aluminum wire, foil tapes (80-100% coverage). Braiding designed to optimize braid angle, number of picks, wire gauge, and strands for attenuation, flexibility, and shielding effectiveness.

Jacket Materials:

• Polyurethane: Low temp rating, UV resistant, abrasion resistant, flexible (-65 to 85C).
• FEP: High temp rating, chemical resistant, moisture resistant, low smoke, low outgassing (-65 to 200C).

Braid Types:

• Round Braid: Lower material cost, most flexible.
• Woven Flat Braid: Lower contact resistance, better coverage, smoother conductor, increased connector retention.
• Helical Flat Braid: Improved flexibility and shielding, increased phase stability vs flexure, lower radial torque resistance.

Shielding Construction:

• Triple Shield: Woven flat braid, polyimide foil, round braid (>90 dB shielding).
• Double Shield: Helical flat braid, round braid (>100 dB shielding).
• Double Shield: Woven flat braid, round braid (>85 dB shielding).
