This versatile product family has pin counts from 12-100 and board-to-board (BtB) mated stacked heights from 5mm to 10 mm. TE ERNI MicroCon Connectors offer dual-beam female contacts, a wipe length of 1.9mm, and blind mating. These features add to the robustness of this space-saving series. Operating temperatures for MicroCon connectors range from -55°C to +125°C, ensuring this fine-pitch product is an excellent choice for industrial, medical, and aerospace applications.
