TMM-149-02-S-Q

The TMM-149-02-S-Q is a one-row, two-column, molded vertical right-angle header compliant with the TMM-149-02-S-Q specification released by the Insulated Rectangular Connector Subcommittee. It is used primarily in consumer electronics but also in other industries for communication, automotive, military, medical, and industrial applications. In terms of design, the TMM-149-02-S-Q features two single-pole connectors with a pin spacing of 0.200 inches (5.08 mm). It is a right-angle header with tails to allow for a mating connector to be mounted in place. Furthermore, it features a low profile with a maximum height of only 0.303 inches (7.7 mm), with a minimum current rating of 1.0 A.The TMM-149-02-S-Q is composed of a male pin header and a female card-edge connector, with both components being fabricated from thermoplastic polyester UL 94V-0-approved material, rated for 4000 Vrms. The male pin header features tin-plated contacts and has a stand-off feature which enables the male pin header to be firmly attached to the bottom of the female card-edge connector. The insulation materials used for the TMM-149-02-S-Q are designed to be resistant to heat, oils, and solvents, providing environmental protection and allowing for use in harsh environments. The working principle of the TMM-149-02-S-Q is based on the rectilinear motion of the contact pins and corresponding holes between the male pin header and the female card-edge connector. This rectilinear motion occurs when the male pin header is inserted into the female connector, enabling them to make physical contact. When the male pin is inserted, the current flows through the contact point and the contact resistance of the contact pins must be less than 0.4 milli-Ohms to ensure maximum efficiency of current transfer between the two components.Overall, the TMM-149-02-S-Q is an ideal choice for applications that need compact, low-profile connectors for communication, automotive, military, medical, and industrial applications. Its thermoplastic-polyester UL 94V-0-approved construction ensures a high level of environmental protection, and its rectilinear motion between the male pin header and female card-edge connector provides for maximum efficiency of current transfer.
