FX4B3-52S-1.27SV(71) Application Field and Working PrincipleRectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are an array of micro-connector types connecting two printed circuit boards. The types of connectors available in this range are single row and double row, surface mount and through hole, and high and low density. The FX4B3-52S-1.27SV(71) is a single row mezzanine Socket connector type with 1.27mm pitch, 34 contacts in all, and 52 inmold contacts. It is the lowest density of the FX4B3-52 mezzanine range and is suitable for designs that require lower contact counts and compactness.The FX4B3-52S-1.27SV(71) has a number of features that make it suitable for a number of applications. The connector is designed for secure mating and provides enhanced performance against shocks and vibration. It is also rated to a minimum of 500 mating cycles, giving it added durability in the field. This low profile connector is also designed with genderless contacts, providing maximum design flexibility. The FX4B3-52S-1.27SV(71) is also designed to ensure electrical performance over its operational temperature range of -55°C to +125°C, making it suitable for applications where temperatures may change over the life of the product. The contact surface between the mating components is copper-plated with phosphor bronze and the pins are beryllium copper alloy with gold plating. The insulation is high temperature thermoplastic and the header is a standard polyester body with tin-plated copper alloy contacts.This connector is ideal for a range of applications, from medical technology, surveillance, telecommunications and industrial automation, to wireless and wired infrastructure equipment. It is also used for a variety of device interconnect applications; including PC/104 International Standard Computer Modules, industrial controller hubs and distributed I/O solutions.The working principle of the FX4B3-52S-1.27SV(71) is simple. When the mating components of the assembly are mated, electric current is established through the contacts and circulated around the circuit. The contact surface between the components has a low resistance, allowing the current to pass with minimal disruption creating a secure electrical connection.To ensure a reliable connection, the connector is designed with a positive locking mechanism. This prevents accidental disconnection and ensures that the mating components are securely held together and will not dislodge under shocks or vibrations. The FX4B3-52S-1.27SV(71) is a rugged, reliable and versatile connector that is ideal for use in a wide range of applications. It is designed to ensure secure mating, enhanced electrical performance, a long service life and reliable operation in temperatures ranging from -55°C to +125°C.
