IFM O7 Series Photoelectric Sensor

Technical Features

Uses a small housing to reliably detect components in narrow spaces.

The diffuse reflection sensor (with background suppression) model is equipped with a precise light source to accurately detect small objects and resist interference.

Visible red light source for convenient alignment and setup.

Through-beam, retro-reflective, and diffuse reflection (with background suppression) sensors use a fixed detection range for fast setup.

An ideal choice for position detection in parts feeding and material handling applications.

Benefits Introduce In Detail

Powerful Photoelectric Sensors with Small Housings

The O7 series photoelectric sensors are designed for applications detecting small components or where sensor mounting space is extremely limited. With a precise light spot, they can accurately detect small objects at long distances. Typical applications are parts feeding and material handling.

Fixed Detection Range for Fast Setup

The fixed detection range allows the sensor to be plug-and-play, ready to run immediately after installation. The visible red light source helps to complete calibration quickly and easily.

The diffuse reflection sensors with background suppression are available with 30, 50, or 100 mm detection ranges. Other models include polarized retro-reflective models with a 1-meter detection range and through-beam models with a 1.5-meter detection range.
