The SICK GL6G-N4211 is a retro-reflective photoelectric sensor for transparent objects from the SICK G6 series. It has a sensing range of 0.07 m to 5 m with a PL80A reflector, a npn output and an M8 4-pin plug. The housing measures just 12 x 31.5 x 21 mm, runs on 10 to 30 V DC and is rated IP67.<\/p>\n

The G version is tuned for transparent objects. Clear PET bottles, glass jars and plastic film return only a small part of the light, and a normal retro-reflective sensor cannot tell them from clean air. The GL6G resolves that small drop in signal reliably, which is what makes it the sensor used on bottling, filling and film packaging machines.<\/p>\n

The G6 body is the reason this family is fitted so widely. At 12 mm wide it goes where a standard sensor will not, the two through-holes take an M3 screw or the standard SICK brackets, and the whole series shares the same mounting pattern, so a diffuse, a retro-reflective and a through-beam version can be swapped on the same fixture without redrilling anything. Adjustment is by potentiometer, and the output can be set to light switching or dark switching.<\/p>\n

The M8 4-pin plug version is the one to choose when the sensor has to be changed quickly during production: unplug, unscrew, replace, and the machine runs again. It also keeps the cabinet wiring tidy because the cable is a separate standard item.<\/p>\n
