It is part of the ESQT series of flush-locking, 1.54mm pitch, straight-pin connectors. The ESQT-149-02-L-S-309 can be classified under the Rectangular Connectors-Headers, Receptacles, Female Sockets categorization.

The ESQT-149-02-L-S-309 is designed to work in a variety of applications, from web storage and industrial control, to automotive applications, networking and communications, and just about any kind of electronic device. It is a two-part connector, composed of a 2.54mm pitch, single-row, female socket and a matching header. The header and socket are designed to mate in a press-fit, flush locking system that provides a secure, fast connection.

The ESQT-149-02-L-S-309 has a number of features that make it suitable for a variety of applications. It is designed to operate in temperatures ranging from -55°C to 125°C, and its small size (only 4.75mm x 2.25mm) makes it ideal for applications requiring a small footprint. It is rated to 5.0A/contact, and is UL 94V-0 RoHS compliant. Moreover, it is designed to meet the needs of high density, high speed, high reliability applications.

The ESQT-149-02-L-S-309 uses a hinged touch-proof mating system which provides reliable and durable operation. The connector has a low-profile design that results in a flush press-fit interface. The female socket is designed to retain the header in place, while the header side is configured with clips that ensure the socket is securely inserted. The header is available with various contact arrangements, from four up to 90 contacts, ensuring a wide range of applications.

The working principle of the ESQT-149-02-L-S-309 is based on its press-fit flush latching system. The female socket has two locking wings which secure it in place, while the header has a raised boss with two barb-like protrusions which provide strain relief and secure the connection. When the two parts are mated, the female socket\'s locking wings are pushed back by the header boss, allowing the header to be locked into place. This system ensures a tight, secure and reliable connection.
