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

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.
