Stainless-steel photoelectric sensors for harsh environments

20 October 2019

SICK has launched Inox versions of its GR6 rectangular and GR18 cylindrical sensors, to offer tough, high-availability photoelectric senors for detection duties in harsh environments such as chemical washdown or where there may be aggressive oils, lubricants and dust.

Designed for universal compatibility and easy installation in industrial machines, the SICK GR6 Inox and GR18 photoelectric sensors are ECOLAB-certified and feature corrosion-resistant V4A (316L) stainless steel housings rated up to IP69K, combined with specialist screen coatings and seals that ensure high resistance to corrosive chemicals. 

While the GR6 Inox is no bigger than a sugar cube, the GR18 Inox offers standard M18 thread-mounting, so the sensors together present versatile options for through-beam, retro-reflective or proximity sensing duties.  Their precision PinPoint red light or infra-red LED light spot options combine with intelligent signal evaluation that is immune to interference from ambient light, dirt, moisture, and electromagnetic fields. 

The SICK GR6 Inox and GR18 Inox offer complementary choices for electrical connectivity, reflectors and mounting solutions designed for use in challenging environments and washdown conditions. The sensors can also be easily identified after years of use because their product name is laser-etched into the housing surface.
