The QMSS-078-06.75-H-D-PC4 rectangular connectors are part of a family of board-to-board connectors commonly used for modular mezzanine designs. This connector type provides the highest levels of resistance to mechanical shocks, vibration, and other environmental conditions. It can also be used for both single-row and dual-row arrays, as well as for high-speed transmission applications.
These connectors are designed to be used in a variety of demanding applications where high performance and reliability are essential. They offer excellent contact retention with a wide temperature range and high-voltage protection. These connectors generally feature built-in shielding that helps protect against electromagnetic interference (EMI) and radio frequency interference (RFI).
The QMSS-078-06.75-H-D-PC4 connectors are equipped with I/O pins which offer improved signal integrity. They use a terminal pin to carry the current and a floating element to reduce noise transmitted in the power and ground. This design is highly efficient in reducing the I/O inductance and improving signal transmission.
The connectors are available in a variety of styles to meet different application requirements including array edge types and mezzanine board-to-board configurations. The two main styles include threaded-locking and floating-locking connectors. Both styles provide secure connection and reliable performance in the most challenging environments.
The working principle of QMSS-078-06.75-H-D-PC4 rectangular connectors is based on a simple connection principle - the contact element of the external pin is secured to the external ground clip while the contact element of the internal pin makes a connection to the internal socket plate. As a result, a mechanical and electrical connection is formed. The contact elements are held in place by their surrounding insulation material. The latching mechanism holds the two parts of the connector together, ensuring the connection is secure and reliable.
The QMSS-078-06.75-H-D-PC4 connectors offer robust performance and excellent reliability. They feature shielded, high-speed transmission capabilities and are resistant to mechanical shocks, vibration, and harsh environmental conditions. The connectors are suitable for industrial applications including telecommunications, medical equipment, consumer electronics, and automotive applications.
