Rectangular connectors are used for electronic communication and power transmission, most common in consumer and professional audio-video equipment. 3-1971772-3 are a type of rectangular connector, precisely a connector housing for cable assemblies. This type is often used in high-voltage power applications and fiber optic systems.

Overview

The 3-1971772-3 connector housing is premium quality interface for electrical connections and can provide reliable transmission and electrical protection. It is compliant with the European Low Voltage Directive. It is made from thermoplastic, making them lightweight, durable and corrosion resistant. The housings feature opposing wedge fittings which are particularly suited for power and data transmission applications. It has RoHS compliant characteristics, a voltage rating of 300V and temperature rating from -20 to 120°C. The termination style is crimp.

Application Fields

The 3-1971772-3 is used in industrial and telecommunication sectors. It can be used in electric power transmission systems in factories and mines, and in the transferring of data from a central processing unit to peripheral devices. It is usually applied in the systems such as wire harnesses, fiber optics, computing and medical equipment, security, communications, test and measurement, HVAC, audio-visual applications, automotive, military/aerospace, industrial control, lighting, process control, and industrial automation.

Working Principle

The 3-1971772-3 connectors are used for a variety of reasons. When inserted into a jack or panel mount, they provide a secure connection to the board, thus preventing any unintentional disconnection. Oftentimes they are suitable for applications where vibration may occur, preventing or reducing the chances of signal loss. Additionally, they are a more reliable alternative to simple twist-on wire nuts as they provide a stronger and more secure connection. The basic operating principle is that the two wedge fittings are firmly “tied” together and when so, provide a contact between two insulated wires.

Conclusion

3-1971772-3 connectors are widely used in numerous industries, from automation to medical equipment, and are capable of providing reliable and secure conections for both power and data transmission operations. When placed in a jack or panel mount, they provide an even stronger connection than other connectors, making them highly suitable for applications involving vibration. They are lightweight, durable and corrosion resistant, compliant with the European Low Voltage Directive and have many other useful characteristics.
