Is now a good time to invest in purchasing new electronics given component integration trends?
Hirose Electric has released the FX36 Series, a floating board-to-board connector designed for high-temperature and high-vibration industrial environments. The hardware is now available for deployment in compact electronic systems.
Why it matters
The FX36 Series provides a solution for space-constrained automotive powertrain systems that require resilient electrical connections under extreme thermal and mechanical stress.
The connector features a 0.5mm pitch and supports a ±0.5mm effective mating length in the Z-axis, with a design that absorbs vibration amplitudes up to 0.05mm. The two-point contact structure maintains electrical stability during operation at temperatures reaching 125°C.
The players
Hirose Electric
A global electronics manufacturer specializing in high-precision connectors for the automotive, industrial, and telecommunications markets.
The details
The FX36 Series utilizes a floating design, which allows for mechanical shifting between mated components to accommodate mounting misalignment during assembly. Its two-point contact structure ensures redundant electrical pathways, which prevents signal interruption in applications subject to high vibration. These features allow the connector to maintain electrical integrity even when internal components move relative to one another in tight chassis spaces.
Timeline
October 29, 2026: Hirose Electric officially launched the FX36 Series connector.
The Tech Race
As automotive manufacturers shift toward more compact powertrain designs, the race to develop high-reliability, low-footprint interconnects has become critical. This release directly competes with other specialized board-to-board systems aiming to balance high-temperature operation with mechanical tolerance.
Engineers designing compact automotive or industrial electronics can integrate the FX36 into new PCB layouts effective immediately. The component requires no specialized mounting tooling but is intended for use in high-vibration environments where traditional rigid connectors may fail.
The takeaway
The FX36 Series marks a refinement in how board-level connectors handle thermal expansion and mechanical jitter in dense hardware. Interested teams should monitor future manufacturer benchmark reports for long-term reliability metrics under continuous thermal cycling.
