1559-4 Connectors, Interconnects

Terminals - Turret Connectors

A 1559-4 terminal is a type of turret connector used in electrical and electronic manufacturing. It is designed to provide a secure and reliable connection for two or more conductors during operation. The 1559-4 terminals have several common characteristics including gold or silver plating on their contacts and a polarization key to ensure correct connector orientation. The turret design provides space for up to four conductors or wires which are then securely locked in place during operation.

The 1559-4 terminal is a specialized type of terminal designed for applications that require a tight connection. The terminals are machined from brass and can be plated with gold or silver for improved conductivity and long-term performance. The size of the terminals can range from 2.54mm to 3.96mm and have a pin diameter of 1.9mm. The terminals can also be ordered with different spacing requirements which may include either standard or metric pitch sizes.

One of the main features of the 1559-4 terminals is their ability to provide a secure and reliable connection. Each contact is designed to fit tightly into the mating component and can be locked into place for secure operation. The terminals also feature strain relief which prevents any motion from being transferred to the contact which may result in damage to the connection. Additionally, the terminals are rated for high current applications up to 125 amperes and can handle peak currents up to 250 amperes.

The terminals are most commonly used in applications such as military, aerospace, communication, telecommunications, automotive, audio-video, and industrial control. The terminals are suitable for a variety of electrical and electronic installations including home entertainment systems, computer networks, automotive relays, and UPS systems. They are also used in OEM designs, such as robotic arms and RFID transponders.

The working principle of the 1559-4 terminals is based on the principles of electrical contact resistance. When two or more conductors are connected, electrons flow from one to the other, and a voltage is created between the two points. This voltage drives an electrical current through the circuit. The contact resistance of a 1559-4 terminal determines the amount of electrical current that can pass through the connection before damage or failure can occur.

The 1559-4 terminals also offer significant advantages in terms of connection reliability. The connection is secured by a mechanical lock which helps to ensure that the connection remains secure even in the harshest of environmental conditions. The terminals also offer superior corrosion resistance due to their gold or silver plating. These features combine to ensure the terminals provide a stable and reliable connection for many years.

In summary, the 1559-4 terminal is a reliable and secure connection type designed for a wide range of applications. The terminals can be plated with gold or silver for increased conductivity and are rated for high current applications. The mechanical lock and polarization feature help to ensure a secure and reliable connection. The 1559-4 terminals are suitable for home entertainment systems, computer networks, automotive relays, and industrial control applications and offer superior corrosion resistance.
