Do not use it for such purpose. Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Designing the System Power ON The E4E2 needs a maximum of 100 ms to be ready to operate after the E4E2 is turned ON. If power is supplied to the E4E2 and the load independently, be sure to turn ON the E4E2 first. Installation Mounting Mount the Emitter and Receiver so that they face each other in a straight line, and so that they are within the specified sensing distance. Mutual Interference If more than one Sensor is closely mounted together or used in a narrow space, mutual interference of the Sensors will result. Ultrasonic Sensors Sensing Guide Ultrasonic Sensors Other Information E4E2 E4B E4C 1094 Adjustment Sensitivity Adjuster * Check the power indicator (red) of the Emitter, then turn the sensitivity adjuster (ADJ) clockwise as far as it will go. * Be sure not to turn the sensitivity adjuster excessively. If the sensitivity adjuster is turned beyond the permissible range, no sensitivity adjustment will be possible. Indicators * The green indicator on the Receiver shows stability during sound input. Adjust the mounting shaft so that this indicator light brightly when there is no sensing object present. * While passing a sensing object through the path, adjust the operation indicator (red) on the Receiver so that it light and goes out correctly.
