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 several Samtec connector series such as SSW, SSQ, SSM, ESW, ESQ, BCS, BSW, CES, SLW, IDSD, IDSS, SMSD, and SMSS. Available in single, dual, or triple row configurations, with a pitch spacing of 2.54 mm, these headers support 1 to 50 contacts per row in a straight orientation. The contacts are made of phosphor bronze with a gold plating of 10 microinches to ensure high signal integrity and reliability. The insulator is made of natural liquid crystal polymer, capable of operating in a temperature range from -55°C to 125°C. Certifications include UL E111594 and CSA 090871 standards. Optional locking features are available for secure connections. These headers are suitable for industrial applications where high temperature and durability are required.
