Rectangular connectors have been a staple in the electronics industry for decades, boasting notable benefitsfor their flexibility, maintainability and reliability. ESQT-110-03-F-D-XXX connectors belong to this category, catering to small-to-medium size outlets and applications. This article looks at the connectors’ mutual characteristics, application fields and inner working principles.

General Characteristics

ESQT-110-03-F-D-XXX connectors are two-wire configurations, featuring a 3.2mm (0.125in) centerline and a 5.08mm (0.2in) grid pattern. The dual terminals are configured on a straight line, providing secure contact and polarization when mated. The system exhibits good durability, with flammability rated UL 94V-0 and gold plating satisfying the contact resistance fingerprint.

ESQT-110-03-F-D-XXX connectors are pre-wired, allowing a single, soldered connection to the circuit. The external structure houses a black polycarbonate housing, offering reliable thermal and chemical protection. Contacts are tin (Sn) plated over copper (Cu), providing a strong and corrosion-resistant connection.

Applications

ESQT-110-03-F-D-XXX connectors are predominantly used in a variety of output and signal wiring, particularly in industrial automation. Common applications include industrial lighting systems, security systems, and control systems.

Additionally, the dual-wiring design makes them a suitable fit for intelligent buildings, allowing them to effectively connect and manage a range of sensors and other devices. Furthermore, the fire-resistant material makes them an ideal choice for fire safety systems. Other common uses include power supply wiring, machine vision systems, and communication systems.

Working Principle

Connectors from the ESQT-110-03-F-D-XXX family make use of an axial-lock mechanism. This mechanism ensures constant contact by fully embedding the two plug wires into the receiving component’s housing. The groove of the locking mechanism firmly clamps the plug wires’ terminal when in place, keeping them securely connected and foolproof against misalignment.

Moreover, these connectors are part of a range consisting of different varieties and corresponding accessories. Not only do they allow a comprehensive and hardware-linked solution for many applications, they also enable users to bring customized configurations tailored to their needs.

Conclusion

The modular and versatile nature of the ESQT-110-03-F-D-XXX connectors makes them a formidable option for diverse range of applications and environments. From industrial automation to fire safety systems, these connectors offer reliable connections through their axial-lock mechanism and diverse accessories.
