HLK-FPM383F Mini Capacitive Fingerprint Sensor – 3.3V UART

The HLK-FPM383F is a next-generation capacitive fingerprint recognition sensor designed to outperform traditional optical sensors in size, speed, and accuracy. Built on advanced capacitive sensing technology, it accurately detects fingerprint signals with high-speed response times, making it an ideal choice for modern security and identification systems.

Optimized for Battery-Powered Systems

This sensor is specifically engineered for small systems requiring long battery life. It operates with a low supply current and features a highly efficient sleep mode that draws a maximum of only 25 microamperes. Whether in active use or low-power standby, the HLK-FPM383F responds quickly and appropriately to ensure system reliability.

Industrial-Grade Durability

Despite its small form factor, the HLK-FPM383F is remarkably robust. It features a ±15 kilovolt static protection rating, ensuring it is not easily damaged by electrostatic discharge. Additionally, its wide operating temperature range allows it to function reliably even in harsh winter conditions.
