BM22-4S-V(51) Description

Short technical summary and product information.

The BM22-4S-V(51) is a receptacle from the Hirose BM22 series, designed for FPC-to-board connections. It features a hybrid contact layout with 2 signal and 2 power contacts, enabling up to 4A on power contacts and 0.3A on signal contacts at 50V. The two-point contact structure on both power and signal contacts ensures reliable electrical connections. The connector also provides a click feeling for mating confirmation and 0.3mm self-alignment via guide ribs.

 

Key specifications include a low profile 0.9mm insulation height, surface mount termination with solder, and a friction lock for secure mating. The black housing is made of UL94 V-0 rated material. Contacts are gold plated with 1.97µin thickness. Operating temperature range is -35°C to 85°C. The connector is rated for 10 mating cycles.

 

The connector is designed for space-constrained applications requiring both power and signal in a single small footprint. It supports automated assembly with a pick-and-place vacuum pickup area. The 0.9mm stacking height contributes to thin device designs. The BM22 series achieves a 63% footprint reduction compared to previous Hirose FPC-to-board connectors.
