Photoelectric sensors Test the Best Photoelectric Sensors: E67 Series Long Range Perfect Prox Most photoelectric sensors on the market today can reliably detect light-colored, reflective targets against high contrast, dark-colored backgrounds. But what if your application isn’t “ideal?” What if you’re tasked with sensing a multitude of different targets, all with their own colors, sizes, texture or reflectivity? This is where most sensors fail. The E67 Series Long Range Perfect Prox, on the other hand, was engineered from the ground up with these difficult applications in mind. The Highest Performing Sensor in its Class Background rejection sensors are nothing new; they’ve been on the market for decades. Characterized by an ability to detect objects at a certain distance while ignoring objects beyond that range, background rejection sensors are ideal for applications where mounting a reflector on the opposite side of the sensor might not be ideal. What differentiates the E67 Series is its ability to detect objects that cause trouble for most other sensors—like flat black targets, highly translucent targets, or off angle targets. The E67 Series can see these targets up to an unprecedented eight feet, while completely ignoring even highly reflective objects just beyond that range. Highly visible LEDs indicate power and output status. Internal lenses minimize seams for better sealing. The E67 Series is rated NEMA 6P for highpressure washdown and immersion applications. Accuracy and Repeatability The E67 Series doesn’t just detect tough targets—it does so with unmatched precision. Unlike competitive units, the E67 Series sees different targets at nearly the exact same distance with almost zero variation. See below for a comparison. Black/White Range Differential 80 70 60 Range (inches) The E67 Series Long Range Perfect Prox® sensor was designed with one thing in mind: solve the most difficult photoelectric sensing applications. Through the use of patented optics and Perfect Prox technology, the E67 Series can reliably detect targets regardless of material color, texture, reflectance, contrast or surface shape while ignoring objects just slightly outside the target range. 50 White Target 40 Test the Best 30 Black Target 20 10 0 SICK WT34-B410 Banner Q60BB6AF2000 Eaton E67-LRDP200-HLD Note: Performance based on Eaton in-house engineering tests.

Also consider the cutoff range when selecting a sensing range. Guaranteed cutoff will be approximately 12 in. (30 cm) beyond the sensing range. If a background is present within this zone, adjustments to the application or the sensing range will need to be made. Sensor will detect a 90% reflectance card at this range. Sensor will ignore a 90% reflectance card at this range. Custom ranges are available (built-to-order). Contact Eaton’s Sensor Applications Department at 800-426-9184 for delivery lead times and pricing. The sensing range of this device can be set at the factory to between 60 cm and 240 cm (in 10 cm increments). To order, substitute the range (in cm) in the model number in place of the standard 200 cm. For example, for a device that detects out to 4 ft. equates to 121.92 cm. Rounding up (or down, depending on your needs) to the nearest 10 cm yields a sensing range of 130 cm. Therefore, for a light-operate AC/DC device, you would order E67-LRDP130-KLD.

EXCESS GAIN Product Description (Black) PNP Load Output (Source) (-) For connector versions, the pin numbering and wire colors are typical of several manufacturers, 10 however variations are possible. In case of discrepancies, rely on function indicated and pin location rather than pin number or wire color. 1 0.1 10 20 30 40 50 60 70 100 RANGE (inches) Excess gain is a measurement of how much sensing power a photoelectric sensor has available beyond the power required to detect an object. An excess gain of 1.00 at a given range means there is exactly enough power to detect an object under perfect conditions at that range. In the real world, there is contamination—dust, humidity and debris—that can settle on the lenses and reduce light transmission. As the level of contamination gets worse, more excess gain will be needed to get past the poor visibility.
