Rectangular Connectors, commonly referred to as Headers, Receptacles and Female Sockets, are widely used in a variety of applications and settings in for signal and power transmission. This article will focus on one particular type of rectangular connector, the MQ172-3PA(30), and will discuss its application field and working principle.

The MQ172-3PA(30) is a three-way 1.27mm pitch receptacle and can be used for applications in which signal transmission over a power line is required. The receptacle is designed with an insulation displacement contact (IDC), which enables signal lines to be easily connected to the receptacle without the need for soldering or connectors. This eliminates the risk of soldering errors and makes the connection more reliable.

The MQ172-3PA(30) is also designed to be compatible with a variety of insulation types, including Teflon, Polyimide, Silicone, and Polyethylene. This ensures that the connection is able to withstand temperatures of up to 105°C without experiencing any degradation in performance. In addition, its compact size and low profile design make it ideal for applications where space is limited.

The MQ172-3PA(30) is designed to offer up to 3A of power and 0.5A of signal current. This makes it suitable for a range of applications, including communication systems, computers, and other devices. The connector also has a voltage rating of up to 125 VAC/VDC, ensuring reliable signal and power transmission.

In terms of its working principle, the MQ172-3PA(30) connector works by utilizing the IDC contact. The IDC contact is made up of a pair of metal sheets, each containing an array of holes running in a parallel fashion. When the connector is mated, a pin is forced through the holes, creating an electrical connection. This allows the connector to easily transfer power and signals without the need for soldering.

In conclusion, the MQ172-3PA(30) connector is an ideal choice for applications requiring reliable signal and power transmission. Its insulation displacement contact design ensures reliable connections without the need for soldering and its compatibility with various insulation types makes it suitable for a range of applications. Moreover, its ability to deliver up to 3A of power and 0.5A of signal current makes it a reliable choice for a variety of devices.
