Frequently Asked Questions - IGS312 IFM

What is the sensing distance of the IGS312?

The IFM IGS312 has a nominal sensing range of 2 mm when flush mounted in steel.

What is the operating voltage of this sensor?

It requires a supply voltage of 10 to 36 V DC. Ensure proper polarity.

Is the IGS312 PNP or NPN?

The IGS312 is a PNP output (normally open) sensor.

Can the sensor be mounted flush?

Yes, it is designed for flush mounting in metal, which reduces the sensing distance to 2 mm.

What is the protection rating?

The housing is rated IP67, meaning it is dust-tight and protected against temporary submersion.

How do I connect the IGS312?

It has a 2-wire DC connection (brown for +V, blue for 0V) with an M12 connector. For PNP NO, load is between output and 0V.

What is the maximum switching frequency?

The maximum switching frequency is 1.5 kHz, suitable for high-speed applications.

Is the housing made of plastic or metal?

The housing is made of stainless steel (1.4305), providing durability in harsh environments.

How do I clean the sensor?

Clean the sensing face with a soft, dry cloth. Avoid solvents or abrasives.

What are common troubleshooting steps if the sensor does not switch?

Check the supply voltage, correct wiring, target material (metal only), and sensing distance. Ensure the target is within range.
