Why Choose the IMO FMM6/AN-3H Inductive Proximity Sensor?
The IMO FMM6/AN-3H is a robust M12 full-metal inductive proximity sensor designed for reliable non-contact detection of metallic objects in industrial automation, machinery and process equipment. As part of the IMO FM full-metal inductive sensor series, it features an AISI 316L stainless steel housing and active sensing face for durable operation in demanding industrial environments.
This sensor provides an enhanced nominal sensing distance of 3 mm in a compact M12 cylindrical housing. Its shielded construction supports flush mounting into suitable metal surroundings, making it ideal for position sensing, component detection and machine monitoring where installation space and mechanical durability are important.
The FMM6/AN-3H operates from a 10–30 V DC supply and provides an NPN normally open (NO) output with a maximum load current of 200 mA. A 200 Hz switching frequency, M12 plug connection and IP67 / IP68 / IP69K protection make it suitable for demanding industrial automation and machine sensing applications.

Reliable Non-Contact Metal Detection
Inductive proximity sensors such as the IMO FMM6/AN-3H detect metallic targets without requiring physical contact. The sensor generates an electromagnetic field at its active sensing face, and the presence of a suitable metal target changes this field, causing the NPN switching output to operate.
The FMM6/AN-3H combines an enhanced 3 mm sensing distance with a compact M12 full-metal housing and robust environmental protection. Its shielded design enables flush installation into suitable metal structures, while the 10–30 V DC supply range and NPN normally open output provide straightforward integration with compatible PLCs and industrial machine control systems.
Typical Applications
- Metal component presence detection.
- Machine position and end-of-travel sensing.
- Industrial automation and assembly equipment.
- Conveyor and material handling systems.
- Production and packaging machinery.
- Washdown and demanding industrial environments.
- Position monitoring of metallic machine components.
