The most common technique used to validate and count coins is to measure the coin’s size using opto-electronic sensors as well as the metal bulk and surface conductivity properties.

Coin validators are required to provide a high level of detection accuracy in real time. Our high-performance STM32 microcontrollers provides the processing capability required to handle these stringent design requirements. In addition, we offer high-precision operational amplifiers, integrated motor control ICs and a range of AC-DC and DC-DC power management and supply solutions.
