The SICK IM18-08NNS-ZW1 and IM18-08NPS-ZW1 are premium-grade magnetic proximity sensors engineered for precise, non-contact detection in automation and process control applications. These sensors feature a rugged M18 threaded cylindrical housing with a standard design, delivering a reliable 8 mm sensing range for non-flush installations. They operate on a DC 3-wire system with NPN switching output and normally open function, making them compatible with a wide range of PLCs and controllers. Built with nickel-plated brass housing and plastic sensing face, the IM18 series withstands demanding industrial environments, supported by IP67 protection and excellent EMC compliance to EN 60947-5-2. Whether for packaging, material handling, or machine tool monitoring, these sensors offer consistent performance with low hysteresis and high reproducibility.
