IFM IFS204 Inductive Sensor IFB3004BBPKG/US-104 4mm PNP IP68

Overview
The IFM IFS204 (IFB3004BBPKG/US‑104) is a compact inductive proximity sensor designed for applications where space is restricted. Featuring a particularly short M12 housing (only 45 mm total length, 29 mm threaded length), this sensor provides reliable non‑contact detection of metal objects up to 4mm in flush‑mountable configuration. The robust stainless steel housing (316L/1.4404) with IP65, IP67, and IP68 protection ratings ensures reliable operation in harsh industrial environments, including dust, temporary immersion, and high‑pressure washdown. The sensor delivers a very high switching frequency of 800 Hz, making it suitable for high‑speed automation processes. The long sensing range minimizes the risk of physical damage to the sensor, while the clearly visible 4‑LED status indication provides instant feedback on switching state. With a PBT sensing face and gold‑plated M12 connector contacts, the IFS204 is built for long‑term reliability in demanding applications.

Key Features

• Original brand new, within warranty period – Factory‑sealed, genuine IFM component with full manufacturer warranty.

• 100% Satisfaction Guarantee – Risk‑free purchase; if you are not completely satisfied, we will replace or refund.

• Particularly short housing for space‑restricted applications – Compact M12 design with total length of 45 mm and threaded length of only 29 mm, ideal for installation in tight machine frames, grippers, and confined spaces where standard sensors cannot fit.

• Long sensing range minimizes physical damage – Flush mountable with a 4mm sensing range (real Sr = 4 mm ±10%, operating distance 0…3.24 mm) allows the sensor to be positioned farther from the target, reducing the risk of collision and mechanical damage.

• Very high switching frequency (800 Hz) – Fast 800 Hz switching frequency enables reliable detection of rapidly moving parts in high‑speed automation applications such as pick‑and‑place, counting, and rotational speed monitoring.

• Robust stainless steel housing for harsh environments – Constructed from stainless steel (316L/1.4404) with a PBT sensing face, rated IP65, IP67, and IP68 for dust‑tight protection, temporary immersion, and resistance to high‑pressure washdown.

• Clearly visible indication of switching status – Four bright yellow LED indicators provide 360° visibility of the switching state, simplifying commissioning and troubleshooting even from a distance.

• PNP normally open output with comprehensive protection – DC PNP, normally open output with 100 mA continuous current rating, and built‑in short‑circuit (pulsed), overload, and reverse polarity protection.

• Gold‑plated M12 connector contacts – Gold‑plated contacts ensure corrosion‑free signal transmission for long‑term reliability in washdown environments.

• Wide operating temperature range – Operates reliably from -25°C to 80°C, suitable for a broad range of industrial applications.

• High reliability with MTTF of 1134 years – Exceptional mean time to failure ensures long‑term dependable operation, minimizing unplanned downtime and maintenance costs.
