High Power
Conectors
Sabritec’s High Power connectors utilize the superior performing Hyperboloid® contact technology, ideal for harsh
and demanding environments with low contact resistance. These connectors provide high current ratings with smaller
contacts for the same power thus saving overall weight and space.
Key Features:
• Low coupling force
• Improved low rate of wear and high coupling durability
• Shock and vibration resistance
• Operate in harsh environments
• Reduced contact resistance
• Contact elements can be insulated, to enable multi-pole use (coaxial)
• Contact mating sequence can be used to gain benets such as power
switching
• Mating of shorter contact can energize main power for system or safety requirements
• Increased power handling capability by 25% as compared to standard contacts

Sabritec also provides rack and panel power and combo layout solutions. A hybrid conguration
consisting of 3 phase power that can be combined with integrated signal, ber optic, coax, triax
and high speed quadrax inserts within a single panel solution. Accessory hardware is available
with custom backshells and power modules exceeding 500 A current ratings.
Buss bars are attached to the threaded end of the connector pin or socket contact or
standard cable crimp terminations for power cable AWG ratings with current ratings up to
500 Amps in a single contact. Blindmate or screw lock accessory hardware congurations are
offered for any rack and panel solutions in a variety of sizes and congurations.
Complete 360 Degree RF connector shielding with EMI ground spring ngers integrated into
each connector shell arrangement and cavity is also available. Modularity is key to the design
with interchangeable insert assemblies available for an array of signal, power and hybrid contact
reverse gender congurations.
