The FTR-117-03-L-D is a type of rectangular connector, and belongs to the family of connectors known as Headers, Male Pins. This type of connector finds application in multiple fields and this article takes a look at the application field of FTR-117-03-L-D in addition to explaining its working principle.

FTR-117-03-L-D is a male header pin with a low profile system which offers high dielectric characteristics. This type of connector features a 3mm centerline with a 5 mm spacing between contact points. It is an ideal solution for applications where space is limited such as in cellular phones, PDAs, digital cameras and in other miniature devices. Other features of this connector include a minimum pin insertion force for less wear on the mating connector, lower stress on the circuit board, and improved long term reliability.

This type of connector is particularly popular for applications in “ruggedized” environment, which is why it finds huge application areas such as aircraft, medical and military sector. The low profile design of FTR-117-03-L-D is resistant to physical stress, making it well suited for high vibration environments. In addition, it offers excellent protection against EMI/RFI from the internal and external environment.

The working principle for this type of connector is based on two conditions - Solder reflow condition and Crimp connections condition. The Solder Reflow condition is used when insertable terminals are attached to the wiring harnesses and when connector is mounted on the PCB. In the Solder Reflow condition, the connectors are soldered into the PCB via a reflow process and the terminals are soldered via wave soldering. The Crimp connection is used when a secure electrical and mechanical connection is required for terminals with bars. This procedure includes the wiring harnesses and cables crimped to the terminals and the cables inserted into the connector. The connector is then mounted onto the PCB and the secure electrical connection is established.

Overall, FTR-117-03-L-D is a popular type of rectangular connector, which is widely used in the ruggedized environment with offers superior protection against EMI/RFI and excellent resistance to physical stress. Its application field includes aircraft, medical and military sectors in addition to small devices such as cellular phones, PDAs and digital cameras. In addition, this type of connector can be secured to the PCB by a soldering reflow connection or by a crimp connection, depending on the application.
