MTSW-102-09-S-D-235

The MTSW-102-09-S-D-235 is a 4-position (2x2) unshrouded male pin header from Samtec's MTSW series. It features a 2.54mm (0.100") pitch and row spacing, making it suitable for board-to-board or cable-to-board connections. The connector has a through-hole mounting style with solder termination, and a push-pull fastening type. The insulation height is 2.54mm, and the overall contact length is 18.54mm (0.730"), with a post height of 5.97mm. The contacts are made of phosphor bronze with a 30µin tin finish over nickel, ensuring reliable conductivity. The insulator is black glass-filled polyester with a UL94 V-0 flammability rating. The operating temperature range is -55°C to +125°C, and it is rated for 3A current. The header is cuttable, allowing customization of pin count. Typical applications include prototyping, test fixtures, and general-purpose interconnect in electronic assemblies. The MTSW series is known for its modified strip design, allowing for various lead styles and pin counts. This specific variant uses lead style -09, which provides an overall contact length of 0.730 inches. The unshrouded design allows for easy mating with standard socket connectors. The through-hole mounting provides robust mechanical connection to the PCB. The tin plating is suitable for many applications, though gold plating options are available in the series.
