A letter sorter, also known as a mail sorter, is a specialized machine designed to sort letters efficiently and accurately. These sorters are capable of processing large volumes of mail, with outputs typically ranging from 40,000 to 60,000 units per hour.

The operation of a letter sorter is usually based on advanced technology that includes optical character recognition, barcode scanners and other automation techniques. The machine captures the address of each letter, reads the barcode or address field and sorts the letter according to its destination.

Letter sorters are often used in large mail distribution centers, post offices, logistics centers and other facilities that require fast and efficient sorting of large volumes of mail. They play an important role in optimizing the postal service process, helping to reduce delivery times and improve delivery accuracy.

The performance characteristics of a letter sorter can vary depending on the model and manufacturer, but typically they offer high speed, accuracy and reliability. Modern letter sorters are often equipped with tracking and reporting features that allow operators to monitor the sorting process and maximize efficiency.

Overall, letter sorters are essential tools for postal service providers and logistics companies that require efficient and reliable sorting of letters and other mail items. Their high performance and accuracy help to ensure the smooth running of the postal service process and increase customer satisfaction.
