Kollmorgen S72402-NANA-NA-030
Model Series: S700 Series Absolute Feedback
Product Overview:
The S72402-NANA-NA-030 is an absolute single-turn resolver from Kollmorgen’s S700 series. It provides absolute position feedback within one mechanical revolution (0°–360°). The model code breakdown: S7 = S700 series, 24 = 24-bit resolution equivalent, 02 = single-turn, NANA = connector/housing variant, NA = electrical spec, 030 = 30mm shaft diameter or specific mechanical variant.
