JP011821U Modular Connectors - Jacks With Magnetics: Application Field and Working Principle

Modular connectors – commonly known as jacks with magnetics – provide a specialized and shielded physical interface designed to provide galvanic insulation for electrical connectivity. The modular connector type provides a mechanical system to protect against transformer and line-inductance-induced signals. Jacks with magnetics are well suited for use in applications requiring enhanced electrical isolation while offering low profile and reliable solutions.

The application field for modular connectors is broad, ranging from basic telephone connections to industrial controls. Modular connectors can be used in a wide range of applications, including telecommunication systems, data acquisition systems, medical devices, industrial robotics, avionics, and electronic instrumentation.

The JP011821U is a modular connector model specifically designed for industrial control connections and data acquisition systems. This jack consists of a low-profile plastic body with small, integrated ferrite cores. It features a shallow connection depth and a single-row configuration with eight pin contacts.

Working Principle:

The JP011821U modular connector provides galvanic isolation between two active signal paths. This is accomplished by inserting two magnetized ferrite cores – one of each contact on either side of the connector body – and by incorporating a plastic insulating material to create an isolating layer around the magnetized cores. The magnetic field produced by the ferrite cores acts as a transformer, inducing an equal voltage on each side of the connector body, thus providing galvanic insulation.

The JP011821U connector offers design flexibility with low power loss. Its metal shell provides shielding to minimize the ingress of EMI/RFI, ensuring a secure connection. The connector is also designed to be IP67 rated, making it suitable for harsh environmental conditions. It is also RoHS Compliant, providing excellent environmental performance and is certified for UL, CSA, and CE.

In conclusion, the JP011821U modular connector offers a reliable, and high performance solution for applications requiring high electrical isolation. Its small size and simple installation make it ideally suited for industrial control connections and data acquisition systems. With its UL, CSA, and CE certification, the JP011821U is a reliable and robust connector solution.
