Description

The IFM Efector IFS240 is a high-performance inductive proximity sensor engineered for precision metal detection in demanding industrial automation settings. Its flush-mount design allows for installation level with the mounting surface, providing reliable detection of ferrous targets at a nominal 4mm distance. The sensor operates on a 10-30V DC supply and delivers a PNP-sourced (sourcing) normally open (NO) switching signal, making it directly compatible with standard programmable logic controllers (PLCs) and industrial input modules.

Constructed with a robust M12 threaded stainless steel housing, the IFS240 is built to withstand harsh conditions, featuring an extensive IP69K rating for high-pressure, high-temperature washdowns. Internal gold-plated contacts ensure stable electrical connection and long-term reliability, while integrated protection circuits guard against reverse polarity, overload, and short-circuit events. The sensor’s wide operating temperature range of -40°C to +85°C ensures dependable performance in extreme environments, from cold storage to hot machinery enclosures.

Key Features

  • Inductive sensing principle for non-contact detection of ferrous metals.
  • Flush-mountable M12 x 1 threaded cylindrical housing for space-constrained installations.
  • Comprehensive protection ratings: IP65, IP66, IP67, IP68, and IP69K.
  • High switching frequency of 700Hz enables use in high-speed counting and positioning.
  • Gold-plated contacts provide enhanced corrosion resistance and stable signal transmission.
  • Built-in reverse polarity, short-circuit, and overload protection for system safety.
  • Extended operating temperature range from -40°C to +85°C.
  • LED status indicator for visual confirmation of output state and power.

Applications

  • Metal part detection and counting on high-speed conveyor systems.
  • Position verification and end-of-travel sensing in automated machinery and robotics.
  • Presence detection of pistons, cylinders, and valves in hydraulic and pneumatic systems.
  • Object detection in washdown and food & beverage processing environments.
  • Safety interlock and door/window monitoring in industrial enclosures.

Frequently Asked Questions

What is the sensing range and target material for the IFS240 sensor?

The IFS240 has a nominal sensing range of 4mm when flush-mounted. It is designed to detect ferrous (iron-based) metals. Non-ferrous metals like aluminum or copper will have a significantly reduced sensing distance and are not recommended for reliable operation.

How do I wire the PNP normally open (NO) output?

Connect the brown wire to your DC positive supply (10-30V), the blue wire to DC negative (0V), and the black wire is the PNP output. In the NO state, the black wire is internally disconnected from the brown wire when no target is present. When a metal target enters the sensing range, the black wire switches to connect to the brown wire, sourcing a positive voltage to your PLC input.

What does the IP69K rating mean for installation?

IP69K indicates the sensor is protected against high-pressure, high-temperature jet washing and steam cleaning. It is sealed against dust ingress (IP6X) and can withstand water jets from any direction at close range (IPX9K). This makes it suitable for food processing, pharmaceutical, and other industries requiring rigorous hygiene cleaning procedures.

Can this sensor be used for high-speed applications?

Yes, with a switching frequency of 700Hz, the IFS240 can detect up to 700 metal objects per second. This makes it suitable for high-speed counting, rotary encoding, and rapid positioning feedback on fast-moving production lines or packaging machinery.
