The IFM OID251 is a laser distance sensor designed for accurate measurement from 0.03 to 2 m. It uses a Class 1 laser and background suppression for reliable target detection. The PNP sensor provides two complementary programmable switching outputs. IO-Link allows parameterisation, diagnostics, and process-data communication. Its M30 cylindrical construction and IP65/IP67 protection make it suitable for industrial automation systems.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The OID251 uses laser-based distance measurement to determine target position within a 0.03...2 m range. Background suppression reduces the effect of unwanted objects behind the target. The visible red laser provides a convenient reference point for alignment. Its 33 Hz sampling rate supports regular distance-data acquisition. These characteristics make the sensor suitable for automated position and object monitoring.
The OID251 supports IO-Link COM2 communication with an IO-Link 1.1 interface. Process data and diagnostic information can be exchanged with the automation controller. The sensor can also operate in SIO mode for conventional switching applications. Two digital PNP outputs provide complementary NO/NC switching. This provides flexible integration into PLC-based systems.
The OID251 uses a threaded M30 housing for secure machine installation. Its IP65/IP67 protection supports normal industrial environments with dust and moisture exposure. A yellow LED indicates switching status while the green LED indicates operating status. The M12 connector provides a standardized electrical interface. These features simplify installation and maintenance.

The OID251 provides reliable distance information without physical contact with the target. Its background suppression helps maintain stable operation when machine structures are located behind the target. The Class 1 laser provides a visible optical reference while maintaining the specified laser safety classification. IO-Link enables additional configuration and diagnostics. This combination provides a practical solution for modern machine automation.
