ESQT-149-02-S-Q-309 Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors in the ESQT-149-02-S-Q-309 range from TE Connectivity (TE) are part of the world-renown ESQT series of products. The range consists of headers, receptacles and female sockets, which were designed to support data transmission applications that require higher performance in a smaller space.

ESQT is a next-generation SMT (surface mount technology) rectangular connector range that delivers increased signal connection layout density and enhanced coupling angle alignment. The ESQT series has a natural zinc nickel finish that increases durability in harsh environments, as well as a patented SMT top latch that provides a secure mount with a wide range of mounting hole thicknesses and different board thicknesses. Its high-temperature plastic material makes the ESQT suitable for use in extreme environmental conditions.

ESQT-149-02-S-Q-309 connectors from TE are designed for data transmission applications that require a compact size and high performance. The connectors feature superior contact resistance and retention force to ensure reliability and enhanced signal integrity in both high-speed and low-speed applications. They also have a high dielectric withstanding voltage and have 100 mΩ minimum initial contact resistance.

The headers and receptacles are designed to accept male ESQT contacts, which are available in sizes 9, 11 and 13, and feature both horizontal and vertical moulding options. The headers are available in two mm pitch, while the receptacles are available with a 6.4 mm pitch and a choice of heights in both 4.6 mm and 8.2 mm. The female sockets feature a 20 mm pitch and come preloaded with square or circular contacts.

Regarding their working principle, the ESQT-149-02-S-Q-309 range of connectors are designed for high-speed and low-speed applications, providing an improved performance over conventional connectors. Each contact is fitted with a spring loaded plunger to ensure a secure connection. The socket contacts are also designed to apply a closing force on the male contact, providing a secure connection. The headers are designed for secure mounting with a top latch, while the receptacle fits flush to the board. Both the header and the receptacle have mounting holes that accommodate a wide range of board thickness.

The ESQT-149-02-S-Q-309 range of rectangular connectors provides an unbeatable solution for data transmission applications. It is the ideal choice for applications where space is at a premium, where robustness and reliability is required and where an optimum performance is desired. It has all the features needed for the successful and efficient transmission of data across all types of applications.
