The G251X is our most popular product for small to medium sized OEM stepper applications. The small footprint (only 1.65”W x 1.3”L x 0.5”H) allows the G250X to fit into the smallest of places and the 0.10” pitch header means it can plug directly into an integrated control board. With a plugin header (available in both male and female versions) you can rest assured that every control box is assembled just as it was designed.
