Circular Connectors - Adapters: PTB22-21PSW Application Field and Working Principle

Circular connectors are soldered electrical interface connectors used in various environments and applications. The most common type of circular connector is the PTB22-21PSW adapter. It has an external locking mechanism and can be used for various audio and power applications. In this article, we discuss the application field and working principle of PTB22-21PSW circular connectors.

Application Field

PTB22-21PSW circular connectors are primarily used in audio applications, including amplifiers, speakers, and other audio-related equipment. They are also suitable for power supply applications, such as 12V DC power supplies, high power switching applications, and more. Moreover, these connectors are widely used in robotic and automation systems, monitoring systems, and other industrial automation applications requiring reliable electrical connections.

Design of PTB22-21PSW Connectors

PTB22-21PSW connectors are designed with a high-strength, L-shaped plastic shell. The shell is designed to be more resistant to wear and tear and is designed with an external locking mechanism. This particular connector features an IP67 waterproof rating, which makes it suitable for use in wet environments. The PTB22-21PSW connector is designed with a type B architecture, which means that there are two mating parts, one male and one female, that fit together to create a reliable connection. The male connector has 21 contacts and the female connector has 22 contacts, which make it suitable for use in audio and power applications requiring more than one connection.

Working Principle of PTB22-21PSW Connectors

The working principle of PTB22-21PSW circular connectors is based on two mating parts, one male and one female. The male connector has 21 contacts and the female connector has 22 contacts. When the two connectors are mated, the locking mechanism ensures that they stay together firmly and securely. The contacts then create permanent electrical connections that ensure reliable transmission of electrical signals. The contacts are designed to evacuate current and heat quickly, which prevents damage to the connectors due to overheating.

Conclusion

PTB22-21PSW circular connectors are reliable and durable electrical interface connectors that are used in various audio and power applications. These connectors are designed with an external locking mechanism and a type B architecture, which ensures reliable electrical connections. Furthermore, the contacts are designed to evacuate current and heat quickly, which prevents damage to the connectors due to overheating.
