SAMTEC BSW12904SS Bottom Entry Socket Strips

The BSW series by Samtec features bottom entry socket strips designed for through-hole mounting, suitable for PCB connections in industrial applications. These low-profile connectors with a 2.54mm pitch accommodate 2 to 36 contacts per row in single, extended, and dual-row configurations (-S, -E, -M, -D). Constructed with a black thermoplastic insulator and phosphor bronze contacts, plated with gold over nickel for durability. They operate reliably between -55°C to 125°C, with a contact resistance of approximately 10mΩ. Ideal for high-temperature soldering, these socket strips are UL and CSA compliant with optional standoff features for versatile mounting options.
