The SAMTEC ZSS series shrouded square post headers offer a robust and reliable connection solution for a variety of applications. These connectors are designed with a shrouded design to prevent mis-insertion and ensure a secure mating. Constructed with a black glass filled polyester insulator and phosphor bronze terminal material, they provide excellent electrical and mechanical performance. Available with various plating options, including gold flash on post and matte tin on tail, these headers cater to diverse needs. They are RoHS compliant and lead-free solderable, making them suitable for modern electronic designs. For added mechanical stability, Samtec recommends using mechanical board spacers in applications with gold or selective gold plated connectors.
