77317-803-50LF Rectangular Connectors - Headers, Male Pins Application and Working Principle

Rectangular Connectors - Headers, Male Pins are a type of device that\'s used to join electrical connections without the need for soldering. They\'re easy to install, require minimal force, and provide reliable connections for a wide variety of electrical applications. The 77317-803-50LF is a type of male pin header designed for use in cable-to-PCB interconnect applications such as those found in industrial automation, medical, military, and telecommunications equipment, amongst others. It combines a low profile 0.050" 2mm pitch with a shallow 4.2mm PCB board mount making it ideal for high density applications that require low profile and miniaturization. The device also features a stand-off mount to help prevent short-circuiting.

Features at a Glance

The 77317-803-50LF provides the following features:

• Low profile 0.050" 2mm pitch
• 45° exit angle
• Stand-off mount
• Polarization feature
• Mates with Molex\'s 77317 Series connectors and sockets
• UL 94V-0 flame rating
• 50 cycles of durability tested
• Operating temperature range of -40° to +105°C

Typical Application and Working Principle

The 77317-803-50LF is designed for end-to-end connector mating when used with Molex\'s 77317 Series connectors and sockets. To ensure reliable mating, the device features a preferred polarization feature that prevents mismating. Once mated, the header provides secure electrical connections that remain discrete and protected from environmental influences.The working principle of the 77317-803-50LF is based on its connection type. This type of male pin header is designed with two internal plated pins connected to the PCB board and surrounded by an insulating plastic body. The contact plating may vary depending upon the application, but for the 77317-803-50LF the pins are plated with 0.76µm thick gold for superior contact reliability.When mated, the two pins have a flush contact with the mating female pins providing secure electrical connections. The internal contacts are pressed and twisted together which provides a secure connection. The stand-off feature of the 77317-803-50LF helps to further ensure the connection is not compromised by vibration, shock, or temperature cycling.

High Reliability

The 77317-803-50LF Rectangular Connectors - Headers, Male Pins have been designed to provide reliable performance. The device has been UL-recognized and features a UL 94V-0 flame rating. Additionally, the device has also been tested under a 50 cycle mating and unmating test to ensure repeatable performance throughout its life. The 77317-803-50LF is the ideal choice for cable-to-PCB interconnect applications that require a low profile, reliable, and highly reliable connection. Due to its combination of features, the device is especially suited for use in challenging industrial, medical, military, and telecommunications applications.
