I-PEX offers high-temperature resistant products that can be guaranteed to operate at temperatures up to 105℃ and 125℃.

In recent years, high heat and high vibration resistance were important for connectors used in automotive and industrial equipment, but these characteristics have also become increasingly important in consumer equipment as well, while equipment and systems have become smaller and more sophisticated. One example is “Mini-LED” backlight technology, in which several thousand micron-sized miniature LEDs are arranged on a highly transparent glass substrate for use in LCD TV backlighting. Compared to conventional LED backlights arranged on printed circuit boards, Mini-LEDs are more efficient, brighter, and have a longer life span. However, the large number of LEDs required and the large number of electronic components densely packed in the control area raise the ambient temperature, leading to an increase in overall heat density. Therefore, connectors must have sufficient heat resistance.

This article introduces the product series best suited for each application that requires high-temperature resistance.

Features of I-PEX high-temperature connectors
I-PEX has designed high-temperature connectors by making full use of our vast  experience, so that they can be used safely even in severe environments where high temperatures and long hours of operation are anticipated.
1.Material Selection
I-PEX selects materials with excellent workability, dielectric properties, and thermal conductivity, as well as stress relaxation characteristics that stabilize spring characteristics even in high-temperature use environments, and materials that can ensure consistent contact. Most of our products are made of phosphor bronze contact material, but we also use Corson alloy for high-temperature products, which is a stronger material without sacrificing the high electrical and thermal conductivity inherent in copper.
2.Design
To obtain stable electrical contact, a certain level of contact pressure is required between mutual contacts. The contacts are made of a metal material and are designed in a spring shape. We focus on designing connectors that make good use of spring characteristics so that they can return to their original position and maintain contact force even during connector insertion,  removal operations and stress relaxation.
Typical example: EVAFLEX® 5-SE-GVT

The contact shape has sufficient deflection (height) to maintain contact pressure even after stress relaxation.
3.Reliability Test
I-PEX is equipped with the following facilities for mechanical performance and environmental testing, as well as conducting reliability testing.
