FMT6/BN-3H IMO Inductive Proximity Switch M30 Shielded, M12 Plug

Why Choose the IMO FMT6/BN-3H Inductive Proximity Sensor?

The IMO FMT6/BN-3H is a heavy-duty M30 full-metal inductive proximity sensor designed for reliable non-contact detection of metallic objects in industrial automation, machinery and process equipment. Part of the IMO FM full-metal sensor range, it features an AISI 316L stainless steel housing and active sensing face for increased mechanical durability in demanding industrial environments.

The FMT6/BN-3H provides an enhanced nominal sensing distance of 10 mm, with an operating distance of 0–8.1 mm. Its shielded M30 construction enables flush mounting into suitable metal surroundings, making it well suited to position sensing, component detection and machine monitoring applications requiring a larger sensing range.

Operating from a 10–30 V DC supply, the sensor provides complementary NPN normally open and normally closed outputs with a load capacity of up to 200 mA. An 80 Hz switching frequency, M12 plug connection, yellow output-state LED and IP67 / IP68 / IP69K protection provide dependable performance across demanding industrial automation applications.

Reliable Non-Contact Metal Detection

Inductive proximity sensors such as the IMO FMT6/BN-3H detect metallic targets without requiring physical contact. The sensor generates an electromagnetic field at its active sensing face, and the introduction of a suitable metallic target alters this field, causing the electronic outputs to switch. This non-contact operating principle helps minimise mechanical wear during repetitive machine cycles.

The FMT6/BN-3H combines a generous 10 mm nominal sensing distance with rugged M30 full-metal construction and complementary NPN outputs. Its shielded design supports flush installation, while the AISI 316L stainless steel construction and high ingress protection make it particularly suitable for machinery where durability, contamination resistance and dependable metal detection are important.
