The Hirose FI-20-CV5(50) is a two-piece plastic backshell designed for the FI series connector family. The gray polycarbonate (PC) housing carries a locking feature that keeps the backshell secured to the connector body once assembled, which matters in any application where the cable gets tugged or the assembly sees vibration.
Fit Check — Does It Match Your FI Connector?
The FI-20-CV5(50) is built for the Hirose FI series and covers exactly 20 positions. The 180° cable exit means the cable runs straight out the back — if your harness needs a right-angle exit, this isn't the one. The locking feature engages with the mating connector housing, so confirm your FI-series plug or receptacle has the matching latch ramp. No cable diameter range is listed in the spec, so verify the cable bundle fits the backshell cavity before committing to the BOM.
