The TFM-126-02-S-D-TR is a rectangular connector, within the headers, male pins category. This type of connector is composed of an insulating plastic body, with a location for the installation of 2 mm pitched pins, characterized as follows.

The body measures 12.6 mm externally, 8.2 mm internally, and is 6.2 mm high. The insulating plastic is UL 94V-0 rated, providing a high level of protection to the connector, and excellent vibration and shock resistance. Its flame retardant and flame retardant halogen free quality.

The contact materials are brass, plated with 6μm gold, allowing for a high resistance to oxidation, and up to 500 mating cycles. Its maximum voltage is 125 VAC, and the impedance is 2 mA.

TFM-126-02-S-D-TR connectors are widely used in applications where electrical or signal transmission is required, including instrumentation, automotive, consumer electronics, computing, medical and office electronics, automation, etc. The advantages include better contact reliability and are popular for their excellent signal integrity, durability and easy assembly.

In regards to the working principle, TFM-126-02-S-D-TR connectors, as well as many other rectangular connectors, involve the insertion of an internal pin into the corresponding female contact, located within the mating connector housing. The insertion is achieved with a lateral displacement of the contact, with an audible click providing an indication of the lock. This insertion creates a friction between the male and female contact, ensuring the contact stays connected with minimal forces.

In addition, the internal pin is designed with an acute angle which is complemented with a corresponding angled contact in the female housing, providing additional resistance to the lateral force, as well as protection against dangerous high currents or electrical shocks. This connection is also configured to provide a low EMI/RFI noise level, making it suitable for signal transmission.

The release of the connection follows similar principles, with the male pin sliding out of the female contact, due to the insertion displacement. Typically, a key-shaped part, located near the contact, must be pressed for the release. This part also acts as a safety guard, ensuring the user does not mistakenly disconnect the contact.

Thanks to its unique design, extensive compatibility with a wide range of applications, and rugged construction, the TFM-126-02-S-D-TR connector is a popular choice for projects requiring reliable power and signal transmissions.
