Samtec TMM Series Straight Through Hole Pin Header, 20 Contacts, 2 mm Pitch, 2 Row, Unshrouded TMM-110-01-G-D

Samtec TMM-110-01-G-D model straight through hole pin header is a high-quality PCB connector designed for reliable electrical connections in electronic assemblies. This header is part of the TMM Series, known for its low profile (2.77 mm height) and precision 2 mm pitch spacing between contacts. The product features 20 male contacts arranged in 2 rows with an unshrouded configuration for straightforward soldering and integration. It supports a maximum current of 3.9A and voltage rating of 500V.

The contacts are crafted from phosphor bronze and plated with gold (0.5 μm on mating pins and 0.075 μm on tail pins) to ensure excellent conductivity and durability, minimizing contact resistance over time. The housing material is black liquid crystal polymer (LCP), providing excellent insulation, mechanical strength, and thermal stability throughout the operating temperature range from -55°C to +125°C.

The through-hole mount type with straight orientation and solder termination makes this header suitable for robust PCB mounting, while the mating pin length of 3.2 mm and tail pin length of 3.5 mm ensure secure electrical connection and mechanical stability. Its low profile makes it ideal for compact and space-constrained applications in industrial electronics, automation, instrumentation, and communication devices.

This pin header is compatible with various Samtec socket series including SQT, SQW, TLE, SMM, and MMS, expanding its usability across multiple board-to-board and wire-to-board configurations.

2 mm pitch with 20 contacts in 2 rows for dense but accessible layout. Unshrouded design for ease of integration and soldering flexibility. Phosphor bronze contacts with gold plating for reliable signal transmission. Liquid crystal polymer housing ensures insulation and thermal resistance.
