The Samtec MTMM-140-09-G-D-355 is a 2.00mm pitch terminal strip header designed for board-to-board or cable connections. It features 80 positions arranged in two rows with all positions loaded. The unshrouded square male pins are made of phosphor bronze with a gold finish (0.51µm thickness) for reliable conductivity.

This through-hole header uses a liquid crystal polymer (LCP) insulator with UL94 V-0 flammability rating, colored black. The overall contact length is 13.59mm, with a mating contact length of 9.02mm. The row spacing matches the 2.00mm pitch for compact layout.

Electrical rating is 3A per contact, with an operating temperature range of -55°C to 125°C. The push-pull fastening type ensures secure mating. This component is suitable for applications requiring high-density interconnections in industrial, automotive, and consumer electronics.
