BM28-10pos.
(+2pos. for
power)
Power lines are concentrated into 2 power contacts
instead of conventional multiple signal contacts.
■Features
1. Rated current 5A
2 Power contacts up to 5A with 0.2A contacts for
signal, space-saving connector.
Usage specification
USB
NFC
Battery
Camera
Earphone jack
2. Highly reliable contact design
2-point contact design for both power & signal
ensures a highly reliable contact
3. Good mating operation
Guide ribs ensure 0.3mm self-alignment. Clear
tactile click prevents partial mating, increases mating
operability.
LCD
Main board
Interface connector
4. Supports USB3.1 Gen.2 (10Gbps) transmission
Signal connector supports USB3.1 Gen.2 transmission
signals.
■Usage
Devices designed to be thinner and smaller, such
as mobile phone, wearable device, tablet PC.

Note 1 : The total current capacity for connectors with 50 or more signal contacts is 10A for all contacts. (Signal contact only)
Note 2 : Includes temperature rise caused by current flow.
Note 3 : Storage refers to long-term-storage of unused items before they are mounted on the PCB.
Operating temperature / humidity range applies to the state of temporary storage such as non-powered after mounting on the
PCB, and during transportation, etc.
