BI5-S18-RZ3X is an inductive proximity sensor designed to detect metal objects without physical contact in industrial automation systems.
Inductive proximity sensors operate by generating an electromagnetic field at the sensing face. When a metal object enters this field, the sensor detects the change and switches its output signal.
The TURCK BI5-S18-RZ3X sensor provides a 5mm sensing distance, allowing accurate detection of metallic objects in automation equipment, CNC machines, conveyor systems, and robotic applications.
Its rugged IP67-rated housing protects the sensor from dust, water, and oil contamination, enabling reliable performance in harsh industrial environments.

Correct wiring ensures proper signal communication between the sensor and the control system.
Inductive proximity sensors detect metallic objects through electromagnetic induction.
During operation:
The sensor generates an electromagnetic field near its sensing surface.
When a metal object enters the field, the electromagnetic field changes.
The sensor detects this disturbance.
The sensor output switches and sends a signal to the control system.
This process allows reliable object detection without mechanical contact.
Sensors detect metal components in automated manufacturing processes.
Robotic systems use proximity sensors to monitor object presence and position.
Sensors detect items moving along conveyor belts to control sorting or stopping mechanisms.
Sensors trigger operations such as labeling, sealing, or filling when products are detected.
Proximity sensors are used for tool positioning, limit detection, and machine safety monitoring.
The TURCK BI5-S18-RZ3X proximity sensor is compatible with many industrial control systems including:
PLC control systems
CNC machine controllers
industrial automation equipment
robotic control systems
Compatibility should be verified based on input requirements of the control system.
The sensor detects metal objects, with best detection performance when sensing ferrous materials such as iron or steel.
The sensor provides a 5mm sensing distance with a tolerance of approximately ±10 percent depending on the target material.
Yes. The IP67-rated housing protects the sensor from dust, water, and oil contamination.
No. The sensor uses non-contact inductive sensing technology.
Using inductive proximity sensors provides several operational advantages:
reliable object detection without mechanical contact
reduced mechanical wear on equipment
fast switching for high-speed automation processes
stable performance in harsh industrial environments
These benefits make inductive sensors widely used in modern automation systems.
