Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESQ-120-48-S-D-LL is a rectangular connector, used to join two electrical components in the context of a header or female socket. It is often used in a variety of industrial, commercial, and consumer electronics applications to facilitate power and data transmission between components while ensuring compatibility with the various operating systems in use. This connector is designed with four single rows of four contact positions on the vertical and horizontal sides, with the same pitch of 2.54mm (0.1”) as the standard. Its high frequency and vibration performance are particularly suited for use in harsh automated systems.

The ESQ-120-48-S-D-LL features a hybrid construction composed of thermoplastics with metal connector plates. This type of construction cannot only offer a durable electrical connection, but also offers improved flexibility and cost-effectiveness compared to conventional metal construction. The connector has a low profile design of 13mm (0.5”), allowing for a space saving mounting out of in tight places. With the contact material crafted of an 80:20 copper alloy, the ESQ-120-48-S-D-LL also presents maximum current carrying capacity, stability, and durability.

The ESQ-120-48-S-D-LL comes with a rated current of 2A and a rated voltage of 600V. It is also RoHS compliant and UL approved. In terms of application fields, it is commonly used in applications where it is necessary to establish and maintain a reliable electrical connection with a signal or power source for data transfer, storage units, automotive wiring, and other applications where repeated mating and unmating is of frequent occurrence.

Working Principle

At the heart of the ESQ-120-48-S-D-LL is an arrangement of specially designed metal connector plates that make contact with mating pins on an electrical component. This is achieved through uniformly spaced slots on the connector plates that each hold a single pin. When the connector mates with an external electrical component, the pins are fit into the slots on the connector plate, creating an electrical connection between the components.

The ESQ-120-48-S-D-LL has a durable thermoplastic construction that provides both electrical and physical protection for the connector plates and connections. This thermoplastic material is able to withstand temperatures ranges from –40°C to 105°C, making the connector well-suited for a variety of applications that are exposed to extreme temperatures. Additionally, the high resistance to shock and vibration allows the ESQ-120-48-S-D-LL to maintain a reliable connection between components even under harsh environmental conditions.

The ESQ-120-48-S-D-LL offers a very cost effective solution for connecting components in a wide range of applications. The hybrid construction of the connector features a low profile design that can be installed in tight places. The use of a copper alloy for the contact material ensures maximum current carrying capacity and the connector’s durability makes it suitable for use in harsh automated systems. Furthermore, the ESQ-120-48-S-D-LL’s RoHS and UL compliance make it a reliable choice that can be integrated into any system with confidence.
