Round, strong, rugged – M18 stainless steel sensor for wash-down applications

The cylindrical photoelectric sensors of the GR18 Inox product family are characterized by a corrosion-resistant V4A (316L) stainless-steel housing. Due to its M18 housing design in short and standard housing lengths, they can be used universally in many applications. The special sealing concept, based on the chemical-resistant O-ring seals, prevents liquids from entering the sensor. Various male connector and connection variants round out the product portfolio.
