LTMM-108-02-S-D-LC

LTMM-108-02-S-D-LC is a board-to-board connector or interconnect header made by Samtec Inc. This connector is part of the Tiger Eye family, a line of .100 (2.54mm) pitch, right angle, board-to-board interconnect products that provide high speed signal transmission. It belongs to the category of rectangular connectors, more specifically headers, male pins.

This connector, in particular, is a single row, 2 position, low stack-height, Tiger Eye mini-catch connector. It incorporates a high retention and secure connection between mating headers, using a mini-catch retention feature. It is unkeyed, and therefore there is no differentiation between power and data connections.

Application Field and Working Principle

LTMM-108-02-S-D-LC is a versatile connector that can be used in a variety of applications, from interconnecting boards in rack mount systems to networking. This kind of connectors can also be found in a number of industrial equipment, as well as in medical applications.

The working principle behind this connector is simple yet effective. The two mating header pins are kept together by means of a vertical force applied by the mini-catch retention feature. This is achieved with two simple steps: locking and unlocking. To secure the connection between the two header pins, the header’s key slot is placed over the mating header pin’s elongated tab. Then, the header is rotated and the mini-catch retention feature will be depressed until it hooks onto the tab. To unlock the two header pins, the reverse procedure needs to be followed.

The connector boasts a reliable connection with a low profile and a small footprint. The parallel positioning of the two contacts allows for an improved signal integrity and better mating alignment, not to mention the enhanced PCB routing capabilities. The LTMM-108-02-S-D-LC helps to save PCB space and, thanks to its low insertion and extraction force, assembly time is significantly reduced.

This connector was tested in accordance with the UL E61442 requirements, and the results showed that its durability is up to 500 cycles. Besides, it presents excellent shock and vibration resistance, making it suitable for harsh environments.

In summary, the LTMM-108-02-S-D-LC is an efficient male connector, due to its small size and light weight, along with its low insertion and extraction forces. It is a reliable solution for a wide variety of applications, including medical, industrial and networking.
