The UB300-18GM40-E5-V1 is a 300mm Ultrasonic Sensor with nickel-plated brass housing and single head system. This sensor use sound waves for measurement, making them ideal for consideration in applications that are difficult to solve with photoelectric devices. The ultrasonic sensor features a switch output with two teachable switching points. This is set by applying the supply voltage -UB or +UB to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 second. LEDs indicate whether the sensor has recognized the target during the TEACH-IN procedure. Switching point A1 is taught with -UB, A2 with +UB.
