Rectangular connectors form a key part of modern electrical and electronics systems and serve as the interface between two components in a wide range of applications. As such, they come in a variety of shapes and sizes to serve the various applications and requirements in proper signal and data transmission. One type of rectangular connector, commonly referred to as the ESQT-120-02-S-D-760, is used for several purposes- from making connections to computer motherboards, to linking various modules in a wide array of electronic systems. This article offers an insight into the application field and working principle of the ESQT-120-02-S-D-760 rectangular connecter.

The ESQT-120-02-S-D-760 Connector

The ESQT-120-02-S-D-760 is a two-row, unshielded, surface mount rectangular connector. It is suitable for a variety of applications, from handheld devices to telecommunications and industrial systems.

The ESQT-120-02-S-D-760 connector is rated for 5A at 300V, with a maximum temperature rise of 40°C in a 60W power dissipative environment with 4mm of air gap between rows. The small size of the connector permits a board mounting area of 3.2mm x 5mm, while allowing a mating area of 159mm x 9.8mm. Its self-locking design ensures reliable mating and un-mating. The ESQT-120-02-S-D-760 contains 4 contact points for signals and 24 contact points for power. The contact points are also hermetically sealed and have a lifecycle of greater than 500 mating cycles.

The Application Field and Uses of the ESQT-120-02-S-D-760 Connector

The ESQT-120-02-S-D-760 is typically used in high-speed, low-power, handheld device applications, such as consumer electronics, telecommunication, and industrial electronics. The connector features a hermetic seal and self-locking design, making it suitable for outdoor and harsh environments. It is also used in applications that require interfacing with multimedia equipment, like printers, scanners, and monitors, or with micro-modules used in automotive electronics systems.

The ESQT-120-02-S-D-760 is also used in high-speed optical communication systems due to its low latency. With its small size, it can also help reduce printed circuit board (PCB) real estate when compared to other connectors of similar performance. This makes it a popular choice for densely packed applications, such as those found in the aerospace and avionics industries, the automotive industry, and military applications.

Working Principle of the ESQT-120-02-S-D-760

The ESQT-120-02-S-D-760 features two rows of contact points, with 4 contact points for signals and 24 contact points for power. The contact points are designed to minimize contact resistance and provide a secure connection.

The solder reflow of the connector is facilitated by a heat-resistant elastomer insert, which ensures a reliable connection with the PCB during the heating and cooling cycle. The contact points are hermetically sealed to provide reliable performance in harsh or outdoor environments. Additionally, the connector also features a spring-loaded latch that provides positive locking and reliable unmating.

The connector also contains two termination seals made from an elastomeric material, which provide a barrier to prevent the entry of dust and moisture into the connector system. This eliminates the need for additional protection and waterproofing methods.

Overall, the ESQT-120-02-S-D-760 rectangular connector is designed to provide reliable connections in a wide range of applications, from handheld devices to industrial systems.
