What is keypad encoder?

A keypad encoder is a device that converts the pressed keys on a keypad into a digital signal or a binary code. It typically consists of a matrix of keys arranged in rows and columns, allowing for efficient input and minimizing the number of required connections. When a key is pressed, the encoder identifies its position and generates a corresponding output signal, which can be used in various applications, such as electronic devices, calculators, and control systems. This enables easy data entry and user interaction in systems requiring numeric or alphanumeric input.
