Hirose Electric BM28 Connectors

Hirose Electric BM28 Connectors are board-to-board and board-to-FPC connectors with rated currents up to 5A, a 0.35mm contact pitch, and 0.6mm stacking height. These connectors use straight SMT type terminations and feature models with both receptacle and header connector types, ranging from 6 to 60 signal contacts. Both the power and signal contacts are copper alloy, gold-plated, and feature a two-point contact design. Guide ribs ensure 0.3mm self-alignment and create a tactile click for added mating confidence, superior reliability, and operability. These halogen-free connectors support USB 3.1, Gen.2 (10Gbps) transmission. Hirose Electric BM28 Connectors are ideal for devices designed to be thinner and smaller, such as smartphones, wearables, and tablet PCs.
