Rectangular connectors are versatile components that can be used in a wide range of applications. From signal and power transmission to process control, they are found in almost every engineering project. One notable type of rectangular connector is the array edge type, mezzanine (board to board) connector, such as ERM8-075-03-L-D-RA-L-TR. In this article, the application field and working principle of this connector will be discussed.

Application Field

The ERM8-075-03-L-D-RA-L-TR connector is a mezzanine (board to board) type rectangular connector that is suitable for signal and power transmission applications. The connector can handle up to 3.3 amps of current per pole, which makes it a perfect choice for connecting two printed circuit boards (PCBs) to each other and transferring low voltage signals and power. The connector is also designed to handle up to 300 VDC, which makes it suitable for use in industrial applications such as heating, ventilation and air conditioning (HVAC) systems.

It also has a high temperature performance and is capable of operating in extreme environments from -55°C to 125°C. This makes the ERM8-075-03-L-D-RA-L-TR connector an ideal choice for use in high temperature and high voltage applications, such as motor control and power distribution systems.

Working Principle

The ERM8-075-03-L-D-RA-L-TR connector is a board to board connector that has two separate parts: one for the male and one for the female. It consists of four pins for the male connector and four corresponding contacts in the female connector. The male and female connectors are mated together by a simple push-on action. The pins on the male connector are then pushed into the corresponding contacts on the female connector to form an electrical connection.

The connector can also be used to make a direct connection between two PCBs, without the need for any additional wiring or components. It is designed with a latching mechanism that ensures secure connection and prevents the connectors from coming apart easily. The latching mechanism also provides additional strain relief for the cables and helps to reduce the risk of damage due to vibration or shock.

In addition to the latching mechanism, the connector is also designed with an anti-corrosion coating that helps to protect against moisture, dirt and other environmental elements. The connector is also designed to reduce crosstalk and electromagnetic interference (EMI) for improved signal quality. This makes it an ideal choice for applications where signal integrity is of utmost importance.

To ensure that the connector is secure, it is recommended to use a retention clip or clamping cable ties. This will help to ensure that the connector is fully secured and that the connection is not disrupted due to vibration or shock. It is also important to use the correct size of screws for the PCBs, as this will help to ensure that the connector is securely mounted and that the contacts are not damaged by over-tightening.

The ERM8-075-03-L-D-RA-L-TR connector is a versatile and reliable connector that has a wide range of application in various industries. Its high temperature performance, anti-corrosion properties and improved signal integrity make it an ideal choice for a variety of applications. The connector is designed for easy assembly and provides a reliable connection between two PCBs.
