Frequently Asked Questions - IFS727 IFM
How do I install the IFM IFS727 sensor?
Mount the sensor using the M12 thread and tighten to the specified torque. Ensure the sensing face is not damaged and that there is space for the sensing range. For non-flush installations, keep the active face free from metallic debris. Connect the M12 plug to a suitable cable; the pinout is listed in the manual.
What is the sensing range of the IFS727?
The sensing range is 4 mm for standard steel targets. The range may vary depending on the target material and size.
What power supply should I use for this sensor?
Connect a DC supply of 10...36 VDC. Ensure the current capacity is sufficient for the sensor output load (max 200 mA).
Can the IFS727 detect non-ferrous metals?
Yes, inductive sensors detect all conductive metals, but the sensing range may be reduced for copper or aluminum. Reduce the distance accordingly or use a ferrite-core sensor for better performance.
How do I connect the sensor to a PLC?
Connect the sensor output (PNP or NPN depending on your model) to the PLC input module. For PNP sensors, connect the load between the output and 0V. Confirm the sensor's output type from the label.
What is the operating temperature range?
The sensor operates reliably from -25 °C to +80 °C, making it suitable for most industrial environments.
How should I clean the IFS727 sensor?
Use a dry, clean cloth to wipe the sensing face. Do not use solvents or abrasive materials, as they may damage the housing or the active surface.
Is the sensor protected against short circuit and overload?
Yes, the IFS727 features short-circuit protection and overload protection on the output, safeguarding it in fault conditions.
What is the IP rating of this sensor?
The sensor is rated IP67, meaning it is dust-tight and protected against temporary immersion in water up to 1 m depth.
Can I use the IFS727 in a washdown environment?
Yes, with an IP67 rating, it can handle washdown, but avoid prolonged exposure to high-pressure water jets directly on the cable joint. Use a properly sealed connector.
