Turck BI5-M18-VN4X Inductive Proximity Switch Sensor

Description:

The Turck BI5-M18-VN4X inductive proximity sensor is used in industrial metal detection and position sensing systems. Commonly installed in conveyor systems, packaging machinery, assembly equipment, machine tools, and automated production lines requiring non-contact object detection with complementary output signals. Maintenance teams and system integrators use this part for replacement, retrofit, expansion, and automation system repairs.

Applications:

The Turck BI5-M18-VN4X is designed for contactless detection of metallic targets in industrial automation environments. It is commonly used in packaging equipment, conveyor transfer systems, robotic assembly cells, and manufacturing machinery where both normally open and normally closed outputs are required for PLC-controlled processes, machine interlocks, and status monitoring applications. The M18 threaded barrel design provides reliable operation in demanding industrial environments.
