Rectangular Connectors - Housings provide an electrical connection between two or more wires, cables, and/or circuits. The contact terminal is the most critical part of the connector. 2-179228-7 is a specifically designed pin and receptacle design, housed in an injection-molded plastic body. This type of connector is 1.02 mm pitch with self-locking and a 3A rated current.

2-179228-7 Application Field

2-179228-7\'s flexibility, combined with its small size and high reliability, make it an ideal choice for applications in a wide range of industries. It is widely used in consumer electronics, medical, automotive, industrial, lighting, computer, wire-to-board and board-to-board applications, from cell phones to large industrial systems.

2-179228-7 is robustly designed for use in tight spaces in rough conditions. It can provide reliable connections for signal, data, and power transfer with no more problems like signal degradation, electromagnetic interference (EMI), thermal cycling, and moisture.

2-179228-7 Working Principle

2-179228-7 working principle is simple and cost effective. It consists of two parts: the plug and the receptacle. The plug is inserted into the corresponding receptacle and, when fully inserted, a cantilever strengthens tabs secure the connector with 6 points of contact in each side. A simple action, such as pressing the unlocking catch or two presses on the tab decouples the plug and receptacle.

The electrical connection is made by two circular guide blades and two contact springs on each side. The springs are pressed together during the insertion process to ensure a low contact resistance. As the contacts are pushed together, a good electrical connection is established and the internal springs provide consistent contact forces.

Technical Features

2-179228-7 is available in two, three, and four-contact configurations for a nominal current of 5A (max. 6A). It has 2mm pitch, 4.5mm length and a 5.2mm-height profile. The contact terminals are made of copper alloy with a gold plating, providing good electrical and chemical properties. Additionally, it is RoHS compliant and its operating temperature range is between -40°C and +105°C.

Conclusion

2-179228-7 is a reliable and cost-effective rectangular connector designed for a wide range of applications. It is robustly designed for use in tight spaces and harsh environments. It provides reliable connections for signal, data, and power transfer with no risk of signal degradation or EMI. Its technical features include 2mm pitch, 5A current rating, and -40°C to +105°C operating temperature range.
