BI5-S18-AZ3X is an inductive proximity sensor designed to detect metal objects without physical contact in industrial automation systems.
The sensor operates by generating an electromagnetic field near its sensing surface. When a metal object enters the detection zone, the field changes and the sensor switches its output signal.
With a 5mm sensing distance, the TURCK BI5-S18-AZ3X sensor is commonly used in automated production systems, CNC machines, conveyors, and robotic equipment where reliable object detection is required.
The sensor uses a PNP normally open output, allowing easy integration with PLC controllers and industrial automation systems.
Its IP67-rated housing protects internal electronics from dust, water, and oil contamination, enabling reliable operation in demanding industrial environments.

Proper wiring ensures stable communication between the sensor and the control system.
Inductive proximity sensors detect metallic objects using electromagnetic induction.
During operation:
The sensor generates an electromagnetic field near the sensing face.
A metal object entering the field disturbs the electromagnetic field.
The sensor detects the disturbance.
The output signal switches and sends a detection signal to the control system.
This detection method allows reliable sensing without physical contact.
Sensors detect metal components during automated manufacturing processes.
Robotic systems use proximity sensors to determine object position and trigger automated movements.
Sensors are used for tool positioning, limit detection, and machine safety monitoring.
Sensors detect objects moving along conveyor belts to control production processes.
Automation systems use sensors to detect products during filling, labeling, and sealing operations.
The TURCK BI5-S18-AZ3X sensor can be integrated with many industrial control systems including:
PLC controllers
CNC machines
industrial automation equipment
robotic control systems
Compatibility should be verified based on the input requirements of the control system.
The sensor detects ferrous metals, with best performance when sensing iron or steel.
The sensor provides a 5mm detection range, with approximately ±10 percent variation depending on target material.
Yes. The IP67 protection rating allows operation in environments exposed to water, dust, and oil.
No. Inductive proximity sensors detect metal objects through non-contact electromagnetic sensing.
Using inductive proximity sensors provides several operational advantages:
reliable metal detection without mechanical contact
reduced equipment wear
fast response for high-speed automation processes
consistent operation in harsh industrial environments
These advantages make inductive sensors widely used in industrial automation systems.
