Why Choose the IMO FMK6/BN-3H Inductive Proximity Sensor?
The IMO FMK6/BN-3H is a robust M18 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 demanding industrial environments.
This sensor provides an enhanced nominal sensing distance of 5 mm in a short M18 cylindrical format. Its shielded construction allows flush mounting into suitable metal surroundings, making it ideal for position sensing, component detection and machine monitoring where a compact and mechanically robust sensor is required.
The FMK6/BN-3H operates from a 10–30 V DC supply and provides complementary NPN normally open and normally closed outputs. With a maximum load current of 200 mA, 100 Hz switching frequency, M12 plug connection and IP68 / IP69K protection, it is well suited to demanding industrial automation applications.

Reliable Non-Contact Metal Detection
Inductive proximity sensors such as the IMO FMK6/BN-3H detect metallic targets without requiring physical contact. An electromagnetic field is generated at the active face, and the presence of a suitable metallic object changes this field, causing the electronic outputs to switch state.
The FMK6/BN-3H combines an enhanced 5 mm sensing distance with full-metal AISI 316L stainless steel construction and complementary NPN outputs. Its shielded M18 design supports flush installation, while the high environmental protection rating makes it suitable for machinery exposed to moisture, contamination and demanding cleaning regimes.
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.
