Rectangular Connectors - Headers, Receptacles, Female Sockets typically offer standard electrical performance with higher power levels. They are commonly used in consumer electronics, industrial machinery, military, and medical applications. The MQ172X-4PA(66) Header/Receptacle is a proven rectangular connector system, designed specifically for these types of applications. Let’s take a look at the main features of this particular connector, as well as its possible applications and working principle.

Features and Applications

The MQ172X-4PA(66) Header/Receptacle connectors include a variety of features that lend themselves to a host of application areas. It utilizes a two-piece design that makes assembly easier and improves airflow and shock-resistance. It is keyed for secure and accurate mating, and contains a toroidal shield that eliminates noise. It is certified to IP67 degree of protection and has both inline and panel mount options, making it suitable for a wide range of applications. Typical applications for the MQ172X-4PA(66) Header/Receptacle, include consumer electronics, industrial machinery, military, and medical applications.

Working Principle

The MQ172X-4PA(66) Header/Receptacle connector operates according to a reliable and standardized soldering process. The properties of the connector are such that it can handle electrical transients up to 500 VDC (300VAC). The contacts are made from phosphor bronze with 10µm gold-plating, providing excellent electrical connection. Its rear-panel receptacle is designed for secure mating, and the shield and integral grommet protect the cable connections from outside elements. It includes two pieces, namely the header (or male component) and the receptacle (or female component). The header is the stationary component that has one row of contacts that is fixed in a chassis or printed circuit board (PCB). The receptacle is the moveable portion that is attached to the cable or directly to the electronics.?

The soldering process begins by heating up the connection while tinning the wire ends. Once the connection is made, the contacts need to be peeled back in order to expose the tail portion of the contact and then the solder is applied. Once the solder is applied and cooled down, the contacts can be covered with a rear-panel receptacle. Once the connection is made, the MQ172X-4PA(66) Header/Receptacle connector is ready for use, providing a reliable and high performance connection.

Conclusion

The MQ172X-4PA(66) Header/Receptacle connector is a proven system for applications in consumer electronics, industrial machinery, military, and medical systems. Its two-piece design improves airflow and offers shock-resistance, and its IP67 degree of protection and a built-in toroidal shield ensures reliable performance. It is designed for easy assembly, high power levels, and accurate mating, and utilizes a foundational soldering process for secure wiring. The MQ172X-4PA(66) Header/Receptacle connector is ideally suited for a variety of applications.
