These parts are in production but have been determined to be LAST TIME BUY. The A1232 is a highly sensitive, temperature-stable magnetic sensor for ring magnet speed/direction systems. It features two precisely aligned Hall switches, internal logic for speed/direction outputs, True Power-On State, and advanced chopper stabilization for high accuracy and low jitter in harsh environments.
