The HTSW series from Samtec consists of high-temperature, unshrouded through-hole terminal strip headers designed for reliable signal connections. These connectors feature 0.025-inch (0.635 mm) square posts and are compatible with various Samtec series connectors including SSW, SSQ, SSM, ESW, ESQ, BCS, BSW, CES, SLW, IDSD, IDSS, SMSD, and SMSS. They are available in single, dual, and triple row configurations with standard pin counts and terminal lengths. The pitch spacing is 2.54 mm, with straight orientation options. Made from phosphor bronze with matte tin plating, these headers operate reliably across a temperature range of -55°C to 105°C. The insulator is constructed from natural liquid crystal polymer, complying with UL and CSA standards. Optional locking leads and clips are available to enhance connectivity reliability.
