This unit utilizes acoustic wave technology to detect objects within a user-selectable range, eliminating the common detection challenges associated with target color, transparency, or surface reflectivity. It serves as a dependable solution for industrial automation setups where physical contact with the target is not feasible or desired.\u003c\/p\u003e\n\n\u003cp\u003eThe sensor features a dual-range selection mechanism that allows engineers to configure the detection zone between 0.3 and 3 meters. Operating at an ultrasonic oscillation frequency of approximately 40 kHz, the \u003cstrong\u003eE4A-3K\u003c\/strong\u003e projects a controlled acoustic cone, ensuring highly precise detection of both metallic and non-metallic objects. Housed in a robust industrial enclosure, this sensor is designed for stationary integration in processing, packaging, and material handling systems.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable dual-range sensing zones (0.3 to 2 meters or 1.3 to 3 meters) for application flexibility.\u003c\/li\u003e\n  \u003cli\u003eNon-contact acoustic detection independent of target color, transparency, or material type.\u003c\/li\u003e\n  \u003cli\u003eHigh-frequency 40 kHz ultrasonic oscillator for reliable signal propagation and echo return.\u003c\/li\u003e\n  \u003cli\u003eRobust mechanical construction capable of resisting significant operational shocks up to 50G.\u003c\/li\u003e\n  \u003cli\u003eClear target resolution suited for pipes, flat plates, and large industrial components.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDiameter, loop, and tension control in paper, plastic, and metal web processing lines.\u003c\/li\u003e\n  \u003cli\u003eLevel and presence monitoring in bulk storage, material hoppers, and packaging lines.\u003c\/li\u003e\n  \u003cli\u003ePosition sensing and collision prevention for automated guided vehicles (AGVs) and overhead cranes.\u003c\/li\u003e\n  \u003cli\u003eObject detection and sorting on heavy-duty conveyor systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eOmron\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eE4A-3K\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eApprox. 2.5 VA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eSensing Distance\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eAdjustable between 0.3 and 3 m (selectable ranges of 0.3 to 2 m or 1.3 to 3 m)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eStandard Sensing Object\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e100-mm diameter, 1.5-m-long metal or plastic round pipe\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eMinimum Sensing Object\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e50 x 50 mm flat plate\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eUltrasonic Oscillation Frequency\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eApprox. 40 kHz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eDirectional Angle\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eHalf-value angle: 25 degrees\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eResponse Time\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eOperate time: 0.25 s; Release time: 0.5 s\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eShock Resistance\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eDestruction: 500 m\/s2 (approx. 50G) 3 times each in plus\/minus X, plus\/minus Y, and plus\/minus Z directions\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eIEC IP60\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eDimensions (H x W x D)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eApprox. 15.9 x 5.0 x 10.4 cm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eApprox. 1.6 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Alignment:\u003c\/strong\u003e Mount the sensor securely to a rigid structure to eliminate vibration.
