The IFM O1D120 is a PMD-based photoelectric distance sensor for precise measurement from 0.2 to 10 m. It uses a visible red laser and background suppression for reliable target detection. Two PNP switching outputs and one configurable analogue output provide flexible control options. A four-digit display allows direct viewing of distance values and programming information. IO-Link enables convenient parameterisation and diagnostics within modern automation systems.

The O1D120 measures distances between 0.2 and 10 m using PMD time-of-flight technology. The sensor can suppress background objects over a range of up to 19 m. A visible red laser spot assists with sensor alignment and commissioning. The measurement system is designed to provide reliable distance information across different target surfaces. It is therefore suitable for automated distance and position monitoring.
The O1D120 provides two programmable PNP digital outputs. One switching output can be configured as either a 4...20 mA or 0...10 V analogue output. The four-digit alphanumeric display indicates distance values and programming information. Yellow switching LEDs and a green operating LED provide additional status indication. This combination provides both local visibility and controller-level measurement.
The O1D120 supports IO-Link COM2 communication for parameterisation and process-data exchange. Its Smart Sensor profile provides identification, process-value, and diagnostic functions. The sensor can operate in SIO mode when conventional switching operation is required. A minimum process cycle time of approximately 6 ms supports automated data acquisition. This makes the O1D120 suitable for connected industrial automation systems.

The O1D120 combines long-range optical measurement with configurable switching and analogue functions. The PMD system provides distance data without requiring a physical contact with the target. Background suppression helps maintain reliable detection when unwanted objects are located behind the target. The display provides immediate information during commissioning and maintenance. These characteristics support reliable automated measurement in industrial machinery.
IO-Link allows the O1D120 to exchange process values and diagnostic information with the machine controller. The sensor can be configured through connected automation software rather than relying only on local adjustment. Conventional switching operation remains available through SIO mode. M12 connectivity provides a standard industrial connection interface. This makes the sensor suitable for both conventional and Industry 4.0-oriented installations.
