HYPERTAC SOCKET CONTACT BRIEFLY
HYPERTAC (= HYPERboloid conTACt) is a socket contact designed and manufactured in such a
manner that, implementing advanced micromechanics technology, satisfies performance requirements
previously considered impossible.
The shape of the sleeve is formed by a springy wires special arrangement. When pin is inserted into this
sleeve every wire stretches to accomodate it, so that wires wrap themselves around pin providing lines of
current paths.
HYPERTAC SOCKET CONTACT, ADVANTAGES
1. ENVIRONMENTAL ADVANTAGES:
- no local hot spot (uniform current densities);
- self-cleaning pin insertion.
2. MECHANICAL ADVANTAGES:
- exceptional electrical continuity under vibration and
shock (very low mass of springy wires, 360° current
paths around pin and redundant current paths);
- low contact engagement and separation forces;
- long contact life (stable time/life contact resistance).
3. ELECTRICAL ADVANTAGES:
- lower contact resistance (redundant current paths);
- higher current rating (lower contact resistance);
- uniform current densities (lower current gradients).
4. USER’S ADVANTAGES:
- HYPERTAC socket contact mates every
conventional cylindrical pin contact.

CHB/CHC Series
CHB and CHC are PCB connectors conforming to
BS9525, NF C 93-424 and ESA SCC 3401.
Contact arrangement is offset-grid pattern, two or
three contact rows within dielectric connector body,
with 2.54 mm center-to-center contact spacing in
each row and 2.54 mm row-to-row spacing.
Contact size is 0.6 mm nominal pin DIA.
Configurations are from 17 to 144 contact positions.
CHB and CHC connectors are also available with
special qualification (see pages 26 and 27)
