Floating BTB connector designed for automotive powertrains

Update: April 30, 2021

Hirose has developed a narrow pitch board-to-board connector ideal for the internal connection of automotive powertrains, including motor controllers. Combining shock and vibration resistance with high heat resistance, the FX26 Series connector provides high reliability in harsh environment applications.

Supporting a floating range of ±0.7mm in the XY direction and ±0.75mm in the Z direction, the series board-to-board connector absorbs misalignment while tightening screws and PCB shrinkage created by high temperatures. The series has a large effective mating length for enhanced performance and reliability.

With a pitch of just 1mm, the series offers PCB space savings, betters assembly times, and decreases cost by replacing traditional cable connectors.

“Traditionally, board-to-board connectors have not been widely used in automotive powertrains due to high heat, vibration and space restraint challenges. The FX26 Series overcomes these issues and delivers high reliability in automotive powertrain applications,” said Mark Kojak, VP of Sales and Marketing for Hirose Electric USA.

The series is offered in various stacking heights, including 15, 18, 20, 23 and 25mm with pin variations of 20, 30, 40, 50 and 60 pins.
