Introduction
The 91601-409ALF is a rectangular connector. It is used to connect two electrical terminal points, often within computer systems. It is a 2 row thru-hole grid array, with 30 positions. Consisting of a header (connector) and a receptacle (socket).

Body
The 91601-409ALF is a rectangular connector, designed with two rows of 15 pins, of which the pitch between them is 2.54mm. The pin length is 0.3mm and the depth of the contact area is 1.41mm. It is designed with terminals (contacts) that connect to the metal leads of a printed circuit board.The connectors are made from high-grade materials, such as copper, gold, stainless steel and titanium. This ensures that it is highly resistant to wear-and-tear, heat, shock and vibration. It is also designed with a low profile, so it does not interfere with other mounted components.

Application Field
The 91601-409ALF connector is used in computers, telecommunication systems, measuring-instrumentation and audio-visual devices. It is widely used in data-processing systems, medical equipment and networking systems.It can be used to connect two terminals, often with fibre-optic or CAT-7 connectors. For example, it can be used as a fibre-optic cable connector, to connect various types of copper and fibre-optic cables. It is also designed with a dust- and waterproof seal, which prevents contamination or damage caused by liquids.

Working Principle
The 91601-409ALF connector works by establishing electrical contact between two terminal points. It operates by providing a large amount of contact force on the pins by the use of metal springs located on each side.This ensures that the electrical contact between the two points is always strong and reliable. The terminators are also designed to reduce contact resistance, providing excellent electrical conductivity and low heat dissipation. The mechanical portion is designed with slotted connections that provide positive locking between the header and the receptacle. This prevents any accidental disconnection.

Conclusion
The 91601-409ALF rectangular connector is a reliable and durable connector. It is designed to provide maximum electrical conductivity and low heat dissipation, with positive locking mechanisms to prevent accidental disconnection. It is widely used in computers, telecommunications systems, measuring instrumentation, audio-visual devices and networking systems.
