All photoelectric sensors use a light source to signal the presence or absence of an object. So one method of classifying these sensors is by how they use that light. The first photoelectric sensors ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

Laser through-beam sensors feature high-accuracy optics that operate to 50 m and have a switching frequency of 5 kHz. The device's narrowly focused beam allows detection of very small objects. A ...

Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric ...

Following the successful introduction of the compact, short-range R10x Photoelectric Series, Pepperl+Fuchs introduces a new series of medium-sized photoelectric sensors for applications with longer ...

Over the past decade, photoelectric sensing has undergone a steady transition in which older, conventional sensors are being replaced by an innovative technology called background suppression (BGS).
