ESQ-109-12-L-D is a type of rectangular connector belonging to the group of Headers, Receptacles, and Female Sockets. These are typically used in electrics and electronics to bridge circuits to enable transmission and reception of signals and power between two points. The ESQ-109-12-L-D rectangular connector has a variety of applications. It is a thermally protected and polarized connector, allowing it to be used both commercially and in industrial settings, from small electronic devices to complex applications.

The name of this connector includes important information that gives insight into its particular specifications. “ESQ” denotes that this particular connector is an economy line. The “109” indicates the number of contacts, while “12” is the total number of rows of contacts and “L” references the length of the power pins, which in this case is 2.54mm. “D” stands for the direction of mounting, which is left when looking at the part from the top.

ESQ-109-12-L-D rectangular connectors are frequently used for industrial, medical equipment, and other electronic devices. The thermally protected feature helps to keep the connector functional under high temperature environments and part misconnections. The polarized contacts eliminate incorrect mating when connecting power circuits in order to protect against short circuits and spark problems which may occur. Additionally, the connector houses a ground spring tab which can be used for transmission of ground signals and reduce any interference.

The working principle of the ESQ-109-12-L-D is quite straightforward. Each contact contains two parts, a male and female. The female pin is an insulator that stays fixed to the connector while the male pins is the interface that connects the power lines of the two circuits. The female is generally slightly longer than the male pins. When the male pin is inserted into the female part, a physical connection is securely made, creating a closed circuit between the two points, which allows power to flow freely.

Unlike other rectangular connectors that may require additional parts for mounting onto a PCB (Printed Circuit Board), the ESQ-109-12-L-D have a unique design that enables direct mounting. This makes the connector much easier to use and reduces assembly time. It also helps to improve reliability and reduce the risk of defects during production, thus reducing the likelihood of failure.

Overall, the ESQ-109-12-L-D rectangular connector is a versatile product that can be used for a variety of applications. Its thermally protected and polarized features make it an ideal choice for both commercial and industrial applications. The firmly secure connection it creates is highly reliable in both high temperatures and power circuits, making it a great choice for ensuring safe and efficient operation.
