KEYENCE introduced the PR-M/F Series, said to be the industry’s first miniature metal photoeye. The PR-M/F Series is intended to fulfill three main focuses: durability, stable operation, and ease of use. By employing a “hybrid structure”, which features a resin filled, SUS316L stainless steel body, the PR-M/F Series sensors are asserted to withstand approximately five times greater shock than conventional models. The heavy duty body is also highly resistant to oils, acids, and alkaline detergents, and maintains both IP67 and IP69K enclosure ratings. These features are combined with an 81 percent reduction in size compared to conventional models, according to the company. The sensor is positioned to ensure stable detection by greatly reducing the effects of interference and target color or angle. By operating at a higher light frequency than most typical light sources, the influence of external light is greatly reduced. Also ,multiple PR-M/F Series sensors will not interfere with each other when used in close proximity, due to its built in cross talk prevention function. The series presents ease of use, simplifying installation by eliminating the need to adjust the sensors.
