The HTSW series from Samtec consists of high-temperature terminal strip headers. These unshrouded, through-hole connectors feature a 0.025-inch (0.635 mm) square post and are compatible with various Samtec connector series 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 optional locking features. The pitch spacing is 2.54 mm, accommodating 1 to 50 contacts per row with straight orientation. These headers operate reliably across a temperature range of -55°C to 125°C, with gold-plated contacts. The terminals are made of phosphor bronze, and the insulator is constructed from natural liquid crystal polymer. They comply with UL and CSA standards and are suitable for industrial applications.
