TecHnology
Smiths Connectors offers an extensive range of superior contact technologies suitable for standard and custom
solutions. Hypertac
®
(HYPERboloid conTACT) is the original superior performing hyperboloid contact technology
designed for use in all applications and in harsh and demanding environments where high reliability and safety
are critical. The inherent electrical and mechanical characteristics of the Hypertac hyperboloid contact ensures
unrivalled performance in terms of reliability, number of mating cycles, low contact force and minimal contact
resistance. The shape of the contact sleeve is formed by hyperbolically arranged contact wires, which align
themselves elastically as contact lines around the pin, providing a number of linear contact paths.
FeATUre
LOW INSERTION/EXTRACTION FORCES
The angle of the socket wires allows tight control of the pin
insertion and extraction forces. The spring wires are
smoothly deflected to make line contact with the pin.
LONG CONTACT LIFE
The smooth and light wiping action minimizes wear on the
contact surfaces. Contacts perform up to 100,000 insertion/
extraction cycles with minimal degradation in performance.
LOWER CONTACT RESISTANCE
The design provides a far greater contact area and the wiping
action of the wires insures a clean and polished contact
surface. Our contact technology has about half the resistance
of conventional contact designs.
HIGHER CURRENT RATINGS
The design parameters of the contact (e.g., the number,
diameter and angle of the wires) may be modified for any
requirement. The number of wires can be increased so the
contact area is distributed over a larger surface. Thus, the
high current carried by each wire because of its intimate line
contact, can be multiplied many times.
IMMUNITY TO SHOCK & VIBRATION
The low mass and resultant low inertia of the wires enable
them to follow the most abrupt or extreme excursions of the pin
without loss of contact. The contact area extends 360° around
the pin and is uniform over its entire length.
The 3 dimensional symmetry of the Hypertac contact design
guarantees electrical continuity in all circumstances.

HIGH DENSITY INTERCONNECT SYSTEMS
Significant reductions in size and weight of sub-system
designs. No additional hardware is required to overcome
mating and un-mating forces.
LOW COST OF OWNERSHIP
The Hypertac contact technology will surpass most product
requirements, thus eliminating the burden and cost of having
to replace the connector or the entire subsystem.
LOW POWER CONSUMPTION
The lower contact resistance of our technology results in a
lower voltage drop across the connector reducing the power
consumption and heat generation within the system.
MAXIMUM CONTACT PERFORMANCE
The lower contact resistance of the Hypertac contact reduces
heat build-up; therefore Hypertac contacts are able to handle
far greater current in smaller contact assemblies without the
detrimental effects of high temperature.
RELIABILITY UNDER HARSH ENVIRONMENTS
Harsh environmental conditions require connectors that will
sustain their electrical integrity even under the most demanding
conditions such as shock and vibration. The Hypertac contact
provides unmatched stability in demanding environments when
failure is not an option.
