Introduction

ESQT-109-03-M-D-309, manufactured by Esec Corp., is a rectangular connector and female socket suitable for use in a variety of applications. Due to its simple design and use of standard connector hardware, the ESQT-109-03-M-D-309 is an ideal choice for quick, reliable connections.

Application Field

The ESQT-109-03-M-D-309 is primarily used in the industrial sector, and is popular for connector solutions in robotics, telecommunications, aerospace, automotive, and medical systems. The ESQT-109-03-M-D-309’s small size makes it a great choice for applications where space is limited, while its robust form factor ensures excellent connection integrity. The ESQT-109-03-M-D-309 is also suitable for use in harsh environments, including high-temperature and high-vibration conditions.

Design

The ESQT-109-03-M-D-309 uses standard 3mm terminal pins for a secure connection. It offers eight pockets of receptacles, which allow for a range of wiring configurations. The low profile of the connector also makes it ideal for thin, light applications. The non-slip design ensures a secure fit in tight spaces, and allows for easy and accurate connection. The connector is rated for a maximum current of 3A and a maximum voltage of 60V.

Working Principle

The ESQT-109-03-M-D-309 is a contact-point based connector, meaning that a physical connection needs to be maintained to ensure a working connection. The pins are arranged in a series, meaning that when a pin is pushed in, it compresses against its neighboring pins, providing a secure and reliable connection. The pressure of the pins also ensures that the contacts remain sealed and dust and moisture cannot enter the connection.

Conclusion

The ESQT-109-03-M-D-309 provides an ideal all-in-one solution for rectangular connector needs. Its low profile and non-slip design make it perfect for applications where space is limited or where a high degree of accuracy is required. Its robust form factor and contact-based working principle make it ideal for applications in harsh environments. This makes the ESQT-109-03-M-D-309 an outstanding choice for a wide variety of industrial applications.
