JST SGN Connector Introduction
The JST SGN Series connectors, with a dimension of 2.0mm pitch, 4.0mm mounting height, and 2.9mm depth, offer numerous advantages for various applications. These board-in-type connectors not only enhance the mounting density of PC boards but also contribute to rationalization and cost reduction in production processes.
With their compact design and low profile, these connectors are particularly suitable for use as internal connectors in low-profile equipment such as audio devices (including car audio) and set-top boxes (STBs). By incorporating the JST SGN Series connectors into these devices, manufacturers can achieve higher levels of integration without compromising on performance or reliability.
The 2.0mm pitch ensures secure connections while allowing for efficient signal transmission between components on the PCBs. The 4.0mm mounting height enables easy installation even in space-constrained environments, making it ideal for compact electronic devices where every millimeter counts.
Furthermore, the 2.9mm depth of these connectors adds to their versatility by accommodating different PCB thicknesses without sacrificing stability or durability.
By utilizing the JST SGN Series connectors in their designs, manufacturers can optimize space utilization within their products while maintaining high-quality electrical connections. This ultimately leads to improved overall product performance and customer satisfaction.

Features
Low profile design
Despite its top entry style, as a result of restraining the connector height, the equipment can be designed without wasting internal space.
Surface usage on the PC board is reduced
The SGN connector is much smaller in width than the existing product. This will help to reduce surface usage without changing the cable.
Reliable mounting
The spring feature of the contact part to the PC board will contribute to accommodating the connector securely even before soldering.
One touch connection
A one-touch operation to make multiple circuit jumper connections will realize the rationalization of production.
