Distance-setting Photoelectric SensorE3G-L1/L3• Reliable detection of differently col- ored, uneven and/or glossy objects in front of defined background (e.g. con- veyors.Features1 mm dia. pin-point beam allows detection of minute objects(E3G-L1)OMRON's unique Hyper LED achieves a pin-point light source only 1/7 the size of conventional light sources, with uniform light-intensity distribution. The Hyper LED achieves stable detection of small objects by eliminating non-detection of objects due to the drop-out which commonly occurs at the center of conventional LEDs.Stable detection is not limited to object color, but also on inclination and glossiness (Inclination characteristic of E3G-L1 is 2.6 times better thanthat of conventional models.)The use of the shining object free optical system with the con- ventional triangulation measuring reduces the discrepancies in sensing distance due to object color, surface, and inclina- tion. (E3G-L3: 2.2 times better than conventional model)The clearly visible spot makes it easy to check the optical axis adjustment and sensing position.Shine-proof OpticalSystem (E3G-L1/L3)Conventional Distance-setting ModelLight source LEDLight source LEDPSDPSDThe distance change by few rise is detected.The center of gravityIntensityOKNGRise of ICA low-error distance signal is as-sured because an image is formed on the position sensitive detectors (PSD), irrespective of the sensing distance. Detection is also stable with respect to the inclination of the object.Imageformationonthepositionsensitive detectors (PSD) is impos- sible at some sensing distances. The spot diameter is large, dis- tance errors occur due to displace- ment of the object center of gravity, and detection is unstable with re- spect to inclination of the object.E3G-L1/L3A-185
