Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

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 ...

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 ...

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 ...

The BBA-4000 is a solar powered wireless infrared break beam system that is simple to install and requires no wiring. The break beam sensors are powered by lithium ion batteries that are recharged ...
