P-type gates, often referred to as P-gates, are a type of entrance control system commonly used in transportation hubs such as train stations, subway systems, and airports. These gates are characterized by their shape, which resembles the letter “P” when viewed from above.

P-type gates typically consist of two retractable barriers that swing open in opposite directions to allow passage when a valid ticket or access credential is presented. After the passage is complete, the barriers automatically close to prevent unauthorized entry.

These gates are efficient in managing pedestrian traffic, offering controlled access while maintaining security. They are often integrated with ticketing or access control systems for seamless operation. P-type gates are favored for their reliability, durability, and ability to handle high volumes of passengers in busy transit environments.
