SA6A Ultrasonic Analog sensor uses fuzzy logic to prevent inaccuracies due to temperature fluctuations. Rugged, compact design features microprocessor with diverse functions. Two specific modes, "fuzzy mode" and "hold mode", perform sophisticated sensing of short distance to long distance. In addition to the analog output, the SA6A has a comparison output that can set far and near limits independently for sensing range. Monitor features a dynamic display of the object position, as well as the far and near limits.
