HMK .100 x .100 Hyperboloid series from IEH

 

 

 

The HYPERBOLOID contact is an advanced design that satisfies performance requirements previously considered impossible. Radically different in concept, it is used in connectors having the highest standards of performance. The distinguishing feature of the HYPERBOLOID socket is the hyperboloid-shaped sleeve formed by straight wires strung at an angle to the longitudinal axis. Viewed from the side, you see a curve defined by a series of apparent short straight line segments which are tangent lines to points along a hyperbolic curve. This geometry provides for a design which has a decreasing circumscribed circle when viewed from the entry. It begins larger than the pin acceptance diameter and is less than this same diameter at the center. When the pin is inserted into this sleeve, the wires stretch, well within elastic limits, to accommodate it. In so doing, the wires wrap themselves around the pin providing a number of continuous line contact paths.

 

The unique geometry, precision processing, and careful attention to quality result in a highly desirable contact design which provides:

  • Very Low Insertion Force
  • Extraordinary Resistance to Shock & Vibration
  • Duty Cycle Exceeding 100,000 Mate/Demate
  • Low, Low Contact Resistance
  • Improved Current Carrying Capacity
  • Highest Reliability

 

IEH company pleased to announce new HMK series connectors.

 

These PCB connectors are .100” (2.54mm) pitch, 2, 3, 4 and 5 rows, with a pin count range of 17-pins all the way up to 490-pins.
