Rugged SICK IME18-12NNSZW2S inductive sensor with 12 mm range, NPN output, IP67 protection, and M18 housing for fast, precise metal detection.
Reliable Sensing for Demanding Industrial Environments
The IME18-12NNSZW2S is a robust inductive proximity sensor from SICK designed to deliver precise, contactless object detection in industrial automation. With a durable M18 nickel-plated brass housing, 12 mm sensing range, and NPN normally open output, it excels in detecting metal objects in tight or rugged environments, including factory automation, packaging, and logistics systems.
This sensor is ideal for engineers and system integrators seeking reliable performance, long life, and effortless integration into 3-wire DC systems.
Modern industrial systems demand speed, precision, and durability—especially in harsh, space-constrained environments. The SICK IME18-12NNSZW2S solves the problem of unreliable mechanical detection by offering non-contact, high-frequency sensing that’s immune to dirt, oil, and vibration. It helps prevent costly downtime, improves process control, and ensures accurate part detection—even when conditions get tough.
