BL 2 70 Z

Headers, Receptacles, Female Sockets Overview

The BL 2 70 Z is a board-to-board header connector manufactured by Fischer Elektronik. It features a 2.54 mm (0.100 inch) pitch and contains 70 contacts arranged in two rows. The component utilizes through-hole mounting for straight installation on printed circuit boards. Contact materials include a CuSn alloy with tin-plated surfaces, while the contact sleeve offers Ni+≥0.2µm Au or Ni+46µm Sn finishes. Designed as a stamped contact spring with a fork contact design, it supports reliable electrical interconnections.
