Frequently Asked Questions - AL3150 IFM
How do I wire the IFM AL3150 switch?
Connect the brown wire to positive supply (10-36 V DC), blue wire to ground, and black wire is the output. Ensure correct polarity to avoid damage.
What is the sensing distance of the AL3150?
The nominal sensing distance is 15 mm for standard metallic targets. Actual distance may vary based on target material and size.
Can the AL3150 detect non-ferrous metals?
Yes, it can detect all metals, but the sensing distance is reduced for non-ferrous metals like aluminum or copper (approx. 30-50% of nominal).
What does the LED indicator on the sensor mean?
The green LED indicates power on. The yellow LED turns on when an object is detected within the sensing range.
Is the AL3150 protected against short circuits?
Yes, the sensor has short-circuit protection and reverse polarity protection for safe operation.
What is the IP rating and can it be used outdoors?
The AL3150 has an IP67 rating, meaning it is dust-tight and can withstand temporary immersion in water. Suitable for damp or outdoor environments.
How should I mount the sensor?
Mount using two M30 nuts (included). Ensure the sensing face is unobstructed and observe the recommended tightening torque of 30 Nm.
What is the maximum load current of the output?
The PNP output can sink up to 200 mA. Connect loads such as PLC inputs or relays directly.
Can I use the AL3150 in high-temperature areas?
The operating temperature range is -25 to 80 °C. For higher temperatures, consider IFM's high-temperature variants.
How do I clean and maintain the sensor?
Clean the housing with a dry, lint-free cloth. Avoid solvents. No regular maintenance is required.
