Product catalog summary

Overview of Hypertac® Hyperboloid Technology
Smiths Interconnect's Hypertac® hyperboloid contact technology is renowned for its reliability and performance in challenging environments. Key features include low insertion/extraction forces, high-density interconnect systems, long contact life, low cost of ownership, reduced contact resistance, low power consumption, higher current ratings, maximum contact performance, and resilience to shock and vibration.

Key Features and Benefits

Low Insertion/Extraction Forces: Smooth mating and un-mating due to socket wire angle control.
High Density Interconnect Systems: Minimizes design size and weight.
Long Contact Life: Up to 100,000 cycles with minimal wear.
Low Cost of Ownership: Exceeds product requirements, reducing replacement costs.
Lower Contact Resistance: Enhanced contact area and clean surface.
Low Power Consumption: Reduced voltage drop lowers power use and heat.
Higher Current Ratings: Design modifications increase current capacity.
Maximum Contact Performance: Handles greater current with less heat build-up.
Immunity to Shock & Vibration: Maintains contact in extreme conditions.
Reliability Under Harsh Environments: Preserves electrical integrity in demanding conditions.

LR Series Connectors
Modular and rugged, the LR Series connectors are suitable for high-demand applications, offering various combinations and compliance with EN45545 standards. They feature low insertion and extraction forces, a wide temperature range, and are RoHS & REACH compliant.

Technical Characteristics
