Functions
Detects metallic and non-metallic objects (glass, plastic, wood, liquids, etc.).
Can operate through non-metallic walls, suitable for level measurement in tanks or liquid control systems.
Precise switching point and low repeat deviation make it ideal for automation processes.
Integrated LED indicator provides visual operation status.
Adjustable sensitivity for flexible applications.
Resistant to environmental influences and vibration – perfect for industrial use.

Applications
For home users: suitable for water or liquid level monitoring, automatic door or valve control, or replacing contact-based detection with a non-contact method.
For engineers/automation specialists: used in automation systems, signal generation, conveyor or robotic line control, and level measurement of liquids or bulk materials.
For electricians: easy connection, compatible with most PLCs and control units.

Pros

Detects both metallic and non-metallic objects.

Adjustable sensitivity adapts to various surfaces and materials.

Dust and moisture resistant.

LED indicator simplifies testing and maintenance.

Cons

Not recommended for installation close to metal surfaces without insulation, as sensitivity may be affected.

Shorter sensing distance compared to inductive sensors for metals.
