Also known as: IFM O1D300 level sensor / distance sensor / laser sensor.
O1DLF3KG/IO-LINK Applications
The IFM O1D300 optical level sensor uses laser time-of-flight to measure level and distance up to about 9.8 m without contact, avoiding wear and deposits associated with mechanical devices. With cm-based level scaling, analog output and IO-Link, it suits bulk-solid and liquid level monitoring in tanks, silos and process plant, backed by a rugged diecast housing and clear display.

O1DLF3KG/IO-LINK – Frequently Asked Questions (FAQ)
What is the measuring range of the IFM O1D300 optical level sensor?
The O1D300 measures 0.2...10 m to a white target (90 percent remission) and to a grey target (18 percent remission), and up to 400.0 cm to a black target (6 percent remission).
What light source does the O1D300 use?
The O1D300 uses visible laser light, protection class 2, with a wavelength of 650 nm and power up to 4.0 mW.
What outputs does the O1D300 offer?
The O1D300 has two outputs: OUT1 is programmable normally open / normally closed, and OUT2 is programmable normally open / normally closed or analogue (4...20 mA or 0...10 V, scalable).
What are the analogue output loads for the O1D300?
On the O1D300, the 4...20 mA output drives a max load of 250 Ohms and the 0...10 V output requires a min load of 5000 Ohms.
Does the O1D300 support IO-Link?
Yes, the O1D300 supports IO-Link revision 1.1 with COM2 transmission at 38.4 kBaud.
What is the operating voltage and protection of the O1D300?
The O1D300 operates on 18...30 V DC, draws less than 150 mA, and has reverse polarity protection plus pulsed short-circuit protection.
What housing, IP rating, and temperature range does the O1D300 have?
The O1D300 has a diecast zinc housing, is rated IP 67, and operates over an ambient range of -10...60 degrees C.
Does the O1D300 have a display and adjustable sampling rate?
The O1D300 has a 4-digit alphanumeric display, an adjustable sampling rate of 1...33 Hz (default 15 Hz), and background suppression over 10...100 m.
