Hirose's compact, FH58 series FPC connectors have a 0.2 mm pitch, mounted depth of 3.1 mm, and a height of 0.9 mm. Combining small size and a light weight, the FH58 series connectors weigh only 0.046 g; making the FPC connector ideal for the growing wearable electronics market.

The FPC connectors have a user-friendly design which includes wide tapers, providing smooth FPC insertion. The FH58 series also incorporates a metal lock mechanism which allows for horizontal FPC insertion / withdrawal and produces a clear, tactile click that insures complete insertion. The FPC tab lock firmly holds the FPC in place until the actuator is locked.

The dual-sided contact design employs a bottom contact spring to provide high reliability and signal continuity. This dual-contact construction, along with the retention spring, delivers a retention force of 15.0 N for the top contact and 14.5 N for the bottom contact.
