This device system can meet these requirements through the use of 3.0 A current, 1.50 mm pitch and a unique side-locking design for an ultra-low profile. The device system also has other robust features such as friction locks that make mating more reliable, mating confirmation marks, and wide solder tabs that wrap around the headers and housings and make PCB retention and mechanical systems more reliable. Systems this small and slim are often difficult for operators to patch. Guide ribs on the housing solve this problem by providing polarization along the mating guide edges. The system features 6-10 circuit sizes and RoHS and low halogen compliant materials. The device uses gold-plated contacts for durability and reliable electrical performance.
