header, dual row, pass-thru, 50-pin

This is the header we use for the -FM and -FM1 connector options on our Adapt-series MCU, application, and accessories products.  It is a quality stackable header at about half the price of the Samtec part we used to use.  Unlike the stackable headers commonly used with Arduino, these pins are square (not rectangular).

• two rows of 25 positions
• 0.1-inch (2.54mm) centers
• 0.025-inch (0.64mm) square pins
• high-temperature black plastic receptacle
• gold-plated contacts and pins
