The TURCK BI4-M12-AP6X is a rugged inductive proximity sensor designed for reliable and space-saving metal detection tasks. With a sensing range of 4 mm and a flush mountable M12 cylindrical housing, it fits well in industrial applications requiring precision, durability, and fast switching. Its PNP output (normally open) ensures compatibility with modern PLCs and control systems, while its 3-wire DC configuration supports simple integration. The sensor’s robust design offers protection against dust, vibration, and moisture, making it ideal for use in packaging, robotics, conveyors, and machine automation. Key Features: • 4 mm flush sensing distance • M12 cylindrical housing – compact and durable • PNP output (NO) – 10…30 VDC operating voltage • LED indicator for switching status • Resistant to oil, dust, and shock – IP67 rating • Suitable for tight mounting spaces • High repeat accuracy and long service life
