Working Principle

The two cage systems in the ESQT-110-03-G-D-340 connector function together to lock the mating parts together, providing reliable, durable connections. The connection is achieved via a series of four interlocking latch systems of two male and two female latches. The male and female latches are separated by a central spring clip, which prevents disconnection due to vibration and external forces. The latches are designed to securely engage with the female connector. The contact system uses a gold-plated copper alloy for enhanced contact reliability and provides a current rating of up to 9A RMS. This is maintained even after repeated mating/unmating cycles, ensuring reliable performance.

Conclusion

ESQT-110-03-G-D-340 rectangular connectors are designed for a variety of electrical and industrial control applications. This includes circuit testing, signal transmission, power supply, and connection of two ports. It is constructed from UL-approved materials and has an IP67 rating, making it suitable for use in harsh environments. The connector integrates two cage systems for contact and mating locking, providing reliable performance and durability. The contact system uses a gold-plated copper alloy for enhanced contact reliability and a current rating of up to 9A RMS. Overall, the ESQT-110-03-G-D-340 proves to be an ideal rectangular connector for many applications.
