Inductive sensors

Inductive proximity sensors detect metal objects without contact and are used for position detection, part counting and checking component presence in machinery and industrial automation systems. Applications include confirming the end positions of mechanisms and monitoring metal parts passing along conveyors or assembly lines.

SELECTION GUIDE

Mounting matters

Flush

The sensing face can sit level with the metal support when the model allows flush mounting.

Non-flush

The active area needs clearance from surrounding metal. Required distances depend on the model.

Distance and target material

Sensing distance depends on the model, target material and target size. Standard sensors may require material correction factors; check factor 1 versions separately.

Sensor output and PLC input

Check supply voltage, PNP/NPN compatibility, NO/NC function and connection. NAMUR sensors require a suitable evaluation interface.

IN PRACTICE

Typical applications

Metal part detection

Detecting and counting metal components on conveyors.

Mechanism position

Confirming the position of moving elements without mechanical contact.

End of travel

Checking the working position of devices and machines.

Gear wheel monitoring

Detecting passing metal teeth to monitor rotation.

Part presence in a fixture

Confirming that a metal component is inserted in a holding fixture.

Assembly line positioning

Checking the position of a metal stop before the next cycle.

Typical technical characteristics

M8, M12, M18 and M30 cylindrical bodies and rectangular housings
Sensing distances from approximately 1 mm to over 40 mm, depending on design
Flush or non-flush mounting
10–30 VDC supply, AC versions and 2-wire NAMUR
PNP, NPN and NO/NC outputs; IO-Link options
M8, M12 or cable connection
Metal or durable plastic housings
Typical protection ratings IP67/IP68/IP69K; ATEX versions depending on the application

How to choose an inductive sensor

Selection starts with the available space and body size, followed by the required sensing distance and mounting conditions. Electrical integration requires checking supply voltage, PNP/NPN/NAMUR output, NO/NC function and connection. Special applications also require consideration of housing material, temperature, IP rating, welding-field resistance, IO-Link or certification for Ex areas.
