ESQ-109-48-G-T

The ESQ-109-48-G-T is a header and receptacle product in the family of rectangular connectors. This particular model is a header with a female socket, which is common when connecting multiple circuit boards, with the header receptacle mounted on one of the boards. The rectangular connector series from the manufacturers is known for its high-end features, such as integrated Keystone EMI and RFI filter, water-resistant and dust-resistant contacts, and Pick & Place compatible components.

The connector is composed of two parts – the header receptacle and the female socket. These components are shielded to help protect against EMI and RFI interference, and to protect against dirt and water. The receptacle of the ESQ-109-48-G-T is made of a high-temperaturethermoplastic material that is rated for up to 105°C, while the socket is made from a stainless steel material with a PTFE backshell. The backshell also serves as a strain relief for the cable used with the connector. The contacts on the receptacle have gold plating to help prevent corrosion.

Many of the features of the ESQ-109-48-G-T make it desirable for a range of applications, such as industrial, telecommunication, commercial, and military. The contact rating of the connector is designed to handle up to 1A, which makes it suitable for low-power applications. Additionally, the integrated EMI/RFI filter helps prevent electromagnetic interference from affecting neighboring devices. The receptacle is also compatible with a range of connector styles such as straight with bulkhead, keyed and polarised, and ganged on board.

The working principle of the ESQ-109-48-G-T involves the connection of two circuits. First, the header receptacle is mounted to one of the boards, connecting the first circuit. Next, the socket is connected to the second circuit. When the two circuits are connected, the contacts on the receptacle line up with the contacts on the socket, allowing the current to pass through. The current is then filtered to reduce interference, and the contacts are sealed to protect against moisture and dirt.

Overall, the ESQ-109-48-G-T provides a highly functional and reliable solution for connecting multiple circuit boards in industrial, telecommunication, commercial, and military applications. The connector’s features such as the integrated Keystone EMI and RFI filter, water-resistant and dust-resistant contacts, and Pick & Place compatible components make it an ideal choice. The working principle of connecting two circuits using the receptacle and socket is straightforward and provides consistent performance.
