FMM6/CP-3H IMO Inductive Proximity Switch M12 Shielded, M12 Plug

Why Choose the IMO FMM6/CP-3H Inductive Proximity Sensor?

The IMO FMM6/CP-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. The FM range features AISI 316L stainless steel construction, including the active sensing face, providing a durable solution for demanding industrial installations.

The FMM6/CP-3H provides an enhanced nominal sensing distance of 3 mm, with a specified operating distance of 0–2.43 mm. Its shielded M12 construction enables flush mounting into suitable metal surroundings, making it particularly useful for machine position sensing and component detection where compact installation is required.

Operating from a 10–30 V DC supply, the sensor provides a PNP normally closed (NC) output capable of switching loads up to 200 mA. A 200 Hz switching frequency, M12 plug connection, yellow output-state LED and IP67 / IP68 / IP69K protection provide reliable performance across demanding industrial automation applications.

Reliable Non-Contact Metal Detection

Inductive proximity sensors such as the IMO FMM6/CP-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 metallic object alters this field, causing the electronic PNP output to change state. This non-contact operating principle helps minimise mechanical wear during repetitive machine cycles.

The FMM6/CP-3H combines a 3 mm nominal sensing distance with compact M12 full-metal construction and a normally closed PNP output. Its shielded design supports flush mounting, while the stainless steel construction and high ingress protection make it particularly suitable for machinery where durability, contamination resistance and dependable sensing are important.
