Product Overview
The Turck IR-B8-M18P-E2-M is a high-performance infrared photoelectric sensor designed for reliable object detection in demanding industrial environments. Featuring an M18 cylindrical stainless steel housing with IP67/IP69K protection, this sensor is engineered to withstand harsh conditions such as dust, moisture, vibration, and high-pressure washdowns. Utilizing infrared light technology, it offers precise detection of objects up to 8 meters, depending on the target surface and environmental factors. The IR-B8-M18P-E2-M operates on a 10–30 V DC supply and provides a configurable PNP or NPN output via an M12 connector. Ideal for logistics, packaging, and automotive applications, this sensor ensures accurate, repeatable performance in dynamic automation systems.
