55510-140 Rectangular Connectors - Headers, Receptacles, Female Sockets

55510-140 is part of the rectangular connector family and is an important component in both parallel and serial electrical applications. It is common in consumer electronics as it offers a high level of signal integrity, interchangeability, reliability, and power handling capability. This connector is found in many professional fields, such as medical, consumer, gaming, lighting, and industrial applications.

Description

The 55510-140 is a high-density, board-to-board connector. It is composed of multiple overall configurations, three in total. Each configuration is comprised of two parts, a male header and a female receptacle. The male header is typically the source of the connection and consists of a slot containing metal pins which mates with the female receptacle’s blade-like characters. This configuration allows for consistent contact and engagement between the two components.The 55510-140 is constructed using a stamped and formed brass shell and a precision die-cast dielectric material, the connecting pins of which are finished with tin-plating. The reversible keyed polarization, as well as a range of mounting configurations, further sufficed this device’s versatility.

Specifications

The 55510-140 offers a maximum voltage rating of 250V and a current rating of 7A. It also has a frequency rating of up to three GHz, and a maximum lined-up speck of 5.08mm between contacts. This connector can deliver up to three connectors per row and features up to twenty-four contacts per row. Other features of the 55510-140 include terminal locks for a secure connection and dual-sided mating. It offers a dielectric strength of 500V AC and an insulation resistance of 1000M Ω.

Application Field and Working Principle

The 55510-140 is used in a wide range of applications, from consumer electronics to industrial and medical fields. Its high-density configuration allows for precise connection between multiple devices, making it suitable for applications in data and audio-video transmission processes. Although designed primarily for board-to-board connections, the 55510-140 is also used for cable-to-board connections. This is done by connecting the female socket to the circuit board, and the male header to the cables. When mated, the pins from the male header slides into the sockets at the female receptacle, connecting with the blade-like characters inside the slots and establishing a reliable connection. The staggered arrangement of the contacts prevent any contact issues, providing a consistent flow of data transmission and signal integrity. The 55510-140 meets the requirements of the UL770 as well as the CSA requirements and is RoHS compliant. It is highly reliable and durable, withstanding high temperatures and vibrations. In conclusion, the 55510-140 is a high-quality, versatile, and reliable solution when it comes to board-to-board and cable-to-board connections. Ideal for application in the medical, consumer, gaming, lighting, and industrial fields, this connector is excellent choice for even the most demanding projects.
