Fingerprint sensor

Fingerprint sensor surface hardness up to 6H, scratch resistant, resolution of 508 DPI, clearer image Large set area, high recognition rate, complies with CE and RoHS international standards
Quantity:

The fingerprint sensor is an ultra-thin CMOS fingerprint sensor that can be used in a wide range of applications such as computer peripherals, access control, time and attendance, and security applications. The diamond coating on the surface provides up to 6H hardness and protects the sensor against scratches, impacts and daily wear and tear. Equipped with an ergonomic guide frame, the A285 guides the user to place their finger on the sensor, resulting in higher recognition performance. The metal frame can effectively improve ESD protection up to 15kV. An 8-pin flex connector on the back side supports a 4-pin SPI interface.
