Rectangular Connectors - Headers, Receptacles, Female Sockets generally refer to electrical connection components with flat contacts on Panel Mount socket or A interconnect and can connect with the flat contacts of male pc board side. Visually, they look like rectangles.

The ESQ-118-48-G-D is a single-row, Low Profile Series Connector, 2.54mm pitch rectangular board-to-board interconnect for high-density applications. It is designed to meet the needs of high-density electronic systems with its high mating cycles (up to 500), strong retention force, and enhanced assembly process. Compatible with most surface mount processes, it uses standard SMT footprints and features a low profile and low insertion force.

The application field of the ESQ-118-48-G-D generally includes portable medical equipment, test and measurement instruments, consumer electronics, computers, automotive electronics, and internet of things applications.

The basic working principle of the ESQ-118-48-G-D Connector is by mating the male board side receptacles with the female socket head. The two sides are connected using the rectangular flat contacts. When they are assembled, the flats on the male board-side connect with the flats of the female socket head side. The two sides are strongly connected after a certain retention force is achieved due to the spring force provided by the contacts.

The ESQ-118-48-G-D Connector is unique not only for its low profile, but also for its contact and retention force system. The contact and retention force system of the connector consists of two mating forces, one is the preload force on the contact and one is the mating force on the contact. When mating the contacts, the preload force compresses the contact springs, causing an increase in contact pressure. The mating force increases the cam lever\'s pressure on the contact spring, which further increases the contact pressure. This increases the contact retention force, which provides reliable electrical contact between the two parts.

The ESQ-118-48-G-D Connector has a wide variety of features, including a low-profile design, high mating cycles, superior retention force, and a compatible surface mount footprint. Due to its features, it is suitable for high density electronic systems with high speed and power signal capability. It is also highly reliable, resistant to vibration and shock, and able to minimize contact resistance. The connector is RoHS compliant and is UL recognized and CSA certified.

In conclusion, the ESQ-118-48-G-D Connector is a great choice for high density electronic systems. It offers many features, including low profile design, high mating cycles, superior retention force, and a compatible surface mount footprint, that make it an ideal choice for applications such as portable medical equipment, test and measurement instruments, consumer electronics, computers, automotive electronics, and internet of things applications.
