The QMS-026-06.75-L-D-A is designed to be easy to use with either hand. It also features a reliable latching mechanism, which is able to survive more than 5000 mating cycles. The connector’s robust design is able to withstand mechanical shock, vibration, and thermal shock. It also features an enhanced pin-in-socket design with individual contact seals and a hermetic shell to reduce the possibility of contamination or corrosion. The QMS-026-06.75-L-D-A is able to operate reliably in temperatures up to +105℃.

Conclusion

The QMS-026-06.75-L-D-A is a versatile and high performance mezzanine edge array connector. It is especially suitable for PCB based systems with limited space. The connector’s reliable connection and robust design make it suitable for a wide range of industrial, electronic, and automotive applications.
