The pitch spacing is 2.54mm, accommodating 1 to 50 contacts per row, with straight orientation. Made from phosphor bronze with a natural liquid crystal polymer insulator, they operate effectively within a temperature range of -55°C to 125°C. The contacts are gold-plated, and the series complies with UL and CSA standards. Optional locking features are available to secure connections, making these headers suitable for industrial applications requiring high signal integrity and reliability.
