Ultra-small, power/signal contact design for Board-to-Board/FPC-to-Board providing 3A max current BM29 Series 20% reduction in size compared with alternate Hiroses products 3.16mm BM29 1.5mm 6 contacts 3.55mm Prior generation product : 1.98mm BM23 6 contacts The narrower and shorter, yet flexible design Fig.1 allows tight installation. Features Combination Power / Signal contact design 1 Space-saving design Compact and flexible design ideal for mobile devices. (Fig.1) Pitch : 0.35mm, Depth : 1.5mm, Stacking height : 0.6mm 2 Equipped with power contacts capable of handling up to 3A current. (Fig.2) Rated current : 3A (power contact), 0.3A (signal contact) 3 The proprietary metal guide prevents the Fig.2 connector from being damaged against offset mating. (Fig.3) Contacts mating is designed to reduce 4 A tactile click ensures secure mating. (Fig.4) connector damage even if mated incorrectly. 5 2-points of contact offer high contact reliability. Metal guides Fig.3 The contact is designed to provide a tactile click. The load plummets. A tactile click Metal locks Fig.4 In cases where the application will demand a high level of reliability, such as automotive, 1 2020.2 please contact a company representative for further information.BM29 SeriesUltra-small, power/signal contact design for Board-to-Board/FPC-to-Board providing 3A max current Product Speci cations Power contact : 3A Operation Storage Rated current -40 to 85C (Note 1) -10 to 60 (Note 2) Signal contact : 0.3A temperature range temperature range Operation 90% RH or below Storage 90% RH or below Rated voltage 30V AC/DC humidity range (Note 3) humidity range (Notes 2 and 3) Items Speci cations Conditions 1.
