Omron Electronics Components Business BV has presented what it considers to be the smallest photomicrosensor on the market, a device that nevertheless offers exceptional detection performance.
Despite its ultra-compact size of just 3.2 mm x 1.9 mm x 1.1 mm, the new EE-SY1200 reflective photomicrosensor can reliably detect objects at a distance of 1 to 4 mm. It is ideal for a wide range of demanding applications, including paper feed and edge detection in office systems and ATMs, as well as motion and fraud detection in the gaming and counter industries, and security applications such as limit switch detection, presence confirmation, and proximity detection of moving parts.
The EE-SY1200, based on Omron's innovative MID (moulded interconnect device) technology, offers a detection solution with a high and reliable signal-to-noise ratio. The EE-SY1200 delivers best-in-class minimum light current to maximum leakage current ratio: 200 µA versus 500 nA. This level of performance allows the system to reliably detect the presence and position of the object.
Gabriel Sikorjak, Product Marketing Manager for Sensors at Omron, commented: “The development of the new EE-SY1200 photomicrosensor further establishes Omron as an innovative provider of high-quality, high-functionality, compact components for sensing and control. The current market for surface-mount reflective photomicrosensors offers few, if any, alternatives to this new sensor. Its exceptional detection range opens up new opportunities for designers seeking sensing solutions where an object needs to be detected as it approaches the detection zone.”.
The device is available in a surface-mount format compatible with automated assembly equipment and is supplied on tape and reel. The sensor is compatible with the most advanced reflow soldering processes. The photomicrosensor operates within a temperature range of -25°C to 85°C.
Photomicrosensors are compact optical sensors that detect objects or object positions using an optical beam. The reflective photomicrosensor incorporates an emitter and a detector. When an object is located within the sensing area of the reflective photomicrosensor, the object reflects the optical beam from the emitter, thus varying the amount of optical energy reaching the detector.
