OMRON announced on October 2, 2017 that it will release the next-generation proximity sensor “E2E-NEXT” and mounting jig “e-jig” that have achieved a detection distance twice that of the company’s conventional products.

In automobiles and automobile parts factories, one-hour equipment outages often lead to large opportunity losses, and reducing the frequency and time of equipment outages has become an important management issue. According to a survey conducted by the company on engine parts manufacturing sites during the development of E2E-NEXT, sudden equipment outages occur for about 1,600 hours a year, of which 15% (about 240 hours) are detected by proximity sensors. It was found that it was due to a collision with an object or a malfunction. By increasing the detection distance of the proximity sensor, it is possible to reduce collisions and malfunctions caused by wear and vibration due to aging of equipment, but with existing technology, detection stability is affected by changes in ambient temperature. Was impaired, making long-range detection difficult.
E2E-NEXT has achieved a detection distance of 40 mm (maximum), which is about twice that of the company’s conventional products, and equipment will stop due to collision failure or malfunction with a detected object in automobiles and automobile parts factories. It is possible to reduce the number of times to 1/3 of the conventional one. In addition, the e-jig reduces the time required to replace the proximity sensor in the event of a failure from the conventional 10 minutes to 10 seconds, so that the location of the failure can be confirmed, part of the device can be disassembled, the sensor can be replaced, wiring, and operation can be performed. A series of operations such as confirmation makes it possible to reduce the recovery time after equipment shutdown, which took about 60 minutes on average, to about 50 minutes.
E2E-NEXT is stable by minimizing the influence of temperature changes by installing “Thermo Distance Control Technology” and “Analog Digital Hybrid IC” that enable highly accurate temperature compensation developed independently. Realized long-distance detection.
Reduced capital investment risk by increasing the detection distance (eg avoiding workpiece collisions over long distances)
With the two products released this time, OMRON will be able to reduce the sudden equipment downtime caused by proximity sensors, which used to be 240 hours a year, to about 67 hours in automobiles and automobile parts factories. It is explained that it will be. The price starts from 7,700 yen for the long-distance type and 11,900 yen for the long-distance anti-spatter type.
