ifm sets new standards Not so long ago sensor market leader ifm electronic Ltd launched a range of M18 photoelectric sensors that set a new benchmark for photocells for use in wash-down conditions. Now they've set the bar even higher! With diffuse, through-beam and retro-reflective versions, the latest WetLine sensors from market leaders ifm electronic Ltd will withstand conditions so harsh that there isn't even a category to describe them. ifm engineers were forced to devise new tests to push the sensors to the limit. Repeatedly simmered at 80°C and then plunged into ice water in an accelerated test, the new devices lasted weeks of simulated operation. This represents years of toil on, say, a cheese production line being hosed down with high pressure hot water and cleaning agents at regular intervals. Other devices available on the market, including ifm’s own, struggled and failed to stand the pace. To reduce ingress points, these M18 sensors all have fixed range and function, so for diffuse object sensors there are three variants with 100mm, 200mm and 300mm ranges. The retro-reflective units work up to 4m and through beam reach 20m. All devices are, of course, fully food-grade stainless steel in construction, apart from the EPDM seals and polycarbonate lenses. All the new WetLine devices are fitted with an industry standard M12 connector. Uniquely, ifm electronic manufactures and supplies a range of connecting cables, the EVT series, equally suited to the rigours of washdown. Further, there is a wide range of stainless steel mounting accessories for a stable installation. For further information on OG WetLine Sensors
