The SAMTEC BDL series is a line of machined board stacking strips designed to provide a low-profile, reliable connection between circuit boards. These connectors feature a design that achieves board spacings as low as (3.89 mm) .153" when mated with SL Series connectors. They offer the flexibility of a separable connection while maintaining the reliability of a permanent connection. Constructed with liquid crystal polymer or glass-filled polyester insulators and phosphor bronze or brass terminals, the BDL series is suitable for a wide range of industrial applications requiring secure and space-efficient board-to-board connections. Note that some lengths, styles, and options are non-standard and non-returnable.
