Samtec TMM Series Straight Surface Pin Header, 50 Contacts, 2 mm Pitch, 2 Row, Unshrouded TMM-125-01-L-D-SM

Samtec TMM-125-01-L-D-SM is a Straight Surface Pin Header part of the TMM Series, featuring 50 contacts arranged in 2 rows with a standard 2 mm pitch. This SMT low profile (2.77 mm height) pin header is designed for use in demanding industrial and electronic applications requiring reliable, high-density PCB connections.

The pin header uses phosphor bronze contacts plated with gold, providing excellent electrical conductivity and corrosion resistance. The male contacts measure 3.2 mm in length with 0.5 mm square posts for robust mating and solder termination. Its polymer housing is made from high-strength black liquid crystal polymer (LCP), ensuring durability and thermal stability.

The device supports a voltage rating of 500 V and a current rating of 3.9 A, capable of handling moderate power loads safely. It reliably operates across an extended temperature range from -55°C to 125°C with gold-plated contacts, making it suitable for harsh environment electronics and industrial equipment.

This pin header is unshrouded and designed for surface mounting, providing ease of assembly and maintenance in compact PCB layouts. It supports board-to-board and wire-to-board connections and mates with multiple Samtec socket series, including SQT, SQW, TLE, SMM, and MMS, offering versatile system integration.

Applications include industrial control systems, communication devices, computing hardware, and other electronic assemblies demanding high reliability and precision. Features phosphor bronze contacts plated with gold for optimal conductivity.
