ESQT-139-03-MM-Q-309

The ESQT-139-03-MM-Q-309 is a type of rectangular connector which is typically used for connecting circuits and devices. It falls into the category of “headers, receptacles, female sockets” and is an important component in many types of electrical equipment and wiring systems. This article will provide a brief overview of the ESQT-139-03-MM-Q-309’s application field and working principle.

Rectangular connectors such as the ESQT-139-03-MM-Q-309 are used in many ways, including for joining together two pieces of equipment, for joining together wires to circuits, for making electrical connections between cable assemblies, and for connecting terminal blocks. They are often used in consumer electronics, telecoms, medical equipment, industrial machinery, and in many other applications.

In general, rectangular connectors consist of two parts: the header and the receptacle. The header is a large connector that is inserted into the receptacle and typically has terminals on the outside to connect to other components. The receptacle is a metal box that contains the header and the terminals. The ESQT-139-03-MM-Q-309 has two rows of 9 pins and is designed for medium-grade applications.

The pins within a rectangular connector such as the ESQT-139-03-MM-Q-309 are divided into five categories: power pins, ground pins, sense pins, current pins, and control pins. The power pins are used to supply power to the circuit, while the ground pins provide a return path for the current. The sense pins provide feedback to the equipment what the voltage and current levels are in the circuit. The current pins and control pins are used to switch circuit elements such as transistors and diodes on and off.

When the ESQT-139-03-MM-Q-309 is inserted into its receptacle, it creates a secure connection. In addition, a secure locking mechanism ensures that the connector will not become disconnected. The connector is also resistant to vibration and shock, which makes it suitable for use in harsh environments.

To get the most out of the ESQT-139-03-MM-Q-309, it is important to understand its working principle. The connector works by providing the necessary path for electrical current and by protecting the circuit components from damage due to surges in current. The header and receptacle protect the circuit components from being exposed to high or low voltages and from becoming shorted out.

The ESQT-139-03-MM-Q-309 is a versatile rectangular connector which can be used in a variety of applications. It is suitable for medium-grade applications and is resistant to vibration and shock. The connector provides a secure connection and is designed to protect the circuit components from damage due to surges in current. Its working principle makes the ESQT-139-03-MM-Q-309 an essential component of many wiring systems.
