The HTSW series from Samtec consists of high-temperature terminal strip headers designed for reliable signal connections. These unshrouded, through-hole headers feature 0.025 inch (0.635 mm) square posts and are compatible with various Samtec connector series such as SSW, SSQ, SSM, ESW, ESQ, BCS, BSW, CES, SLW, IDSD, IDSS, SMSD, and SMSS.
