Coaxial connectors are a type of electrical connector used to carry high-frequency signals through coaxial cables. A particular type of coaxial connector designed for use in radio frequency (RF) applications is the PL3155AC-201. This connector is widely used in telecommunications, radar, test and measurement, and industrial control applications.

The PL3155AC-201 connector is a 75-ohm, push-on type coaxial connector designed for 2.92 mm-sized cables. This type of connector is characterized by its robust construction, which ensures reliable electrical performance up to 6GHz. The connector features an ultra-low profile, making it well-suited for applications with limited space.

The PL3155AC-201 connectors consists of three main components: an inner conductor, an outer conductor, and a dielectric. The inner conductor is a solid metal conductor surrounded by a dielectric material. The dielectric isolates the inner conductor from the outer conductor, which is composed of an outer metal sleeve and a spring-finger latch to provide a secure electrical connection. The spring-finger latch holds the outer conductor firmly in place when the connector is coupled.

The electrical performance of the PL3155AC-201 is dependent upon the contact between the inner and outer conductors, the dielectric isolator material, and the spring-finger latch. The contact between the inner and outer conductors is established by the use of a center pin that penetrates through both conductors and is held in place by the spring-finger latch. The dielectric isolator material provides dielectric protection and prevents electrical arcing between the two conductors, while the latch provides a secure, low-impedance connection.

The PL3155AC-201 connectors offer a reliable, low-impedance connection that provides low insertion and return loss. This makes them ideal for high-frequency applications that require low signal attenuation in order to maintain an acceptable signal level. The connector’s 75-ohm impedance is also compatible with 75-ohm cables used in most applications.

The PL3155AC-201 connector is a widely used, reliable solution for applications where low-loss RF connections are required. By providing secure connections with low insertion and return losses, these connectors have become a popular choice for high-frequency applications in telecom, radar, test and measurement, and industrial control.
