Sensors
Inductive sensors
Festo inductive sensors of the SIED series detect metallic objects without contact via an alternating electromagnetic field and deliver a digital switching output. The series covers thread diameters M12, M18 and M30 in flush and non-flush mountable versions, NPN and PNP switching. Normally-closed (B) and non-flush (NB) thread versions cover the most common mounting bores.
SIED types with ATEX designation -PA are approved for use in explosive atmospheres. Cable exit (L) and M12 connector versions are available for every design. ZO/ZS switching point options allow normally-open and normally-closed switching functions, enabling use in single-wire safety applications.

How to choose Inductive sensors
What matters when choosing: properties, comparison and typical applications.
Technical features
Series by thread diameter
| Thread diameter | Flush / non-flush | Switching distance |
|---|---|---|
| M12 (SIED-M12B) | Flush (B) | typically 2 mm |
| M12 (SIED-M12NB) | Non-flush (NB) | typically 4 mm |
| M18 (SIED-M18B/NB) | B and NB | B: 5 mm / NB: 8 mm |
| M30 (SIED-M30B/NB) | B and NB | B: 10 mm / NB: 15 mm |
Typical applications
Typical applications: End-position and presence detection of metal workpieces in assembly and machining equipment, position detection of workpiece carriers on transfer systems, speed and pulse detection on metal gear wheels and cam discs, tooling presence verification in tool magazines, and safety applications in explosion-protected areas (ATEX Zone 2).
