DWM-17-56-S-D-385 Description

Short technical summary and product information.

Samtec DWM-17-56-S-D-385 is a 34-position, 2-row board stacker header from the DWM series. It features a 1.27 mm (0.050") pitch and 2.54 mm (0.100") row spacing, making it suitable for high-density board-to-board stacking applications. The connector uses through-hole mounting with solder termination and a lead style 56, providing a robust mechanical connection.

 

The contacts are finished with 30 µ" (0.76 µm) gold over 50 µ" nickel, ensuring reliable signal integrity and corrosion resistance. The insulator is black liquid crystal polymer (LCP), offering high temperature stability. The operating temperature range is -55°C to +125°C with gold plating, suitable for demanding environments.

 

The part number suffix -385 indicates a stacker height of 0.385 inches (9.78 mm), allowing precise spacing between parallel PCBs. This connector mates with Samtec SMS, SLM, and RSM series receptacles. It is lead-free solderable and RoHS compliant (unverified).
