Miniature Opto Sensors With Built-In Amplifiers

Whether cubical, cylindrical or custom-shaped, a large selection of compact photoelectric sensors, retroreflective sensors, diffuse reflective sensors, etc. can be found here.

Vacuum Rated Photoelectrics

Picture Productfamily

From low vacuum for grippers to high vacuum at 10-9 mbar for demanding applications in process technology. We manufacture a multitude of vacuum-capable sensors. Designed for the requirements of renowned customers.

Liquid sensors

Picture Productfamily

Based on our unique microoptical precision components we produce sensors for the detection of liquids in transparent tubes or containers. Level- and tube sensors, water sensors or microsensors for fluid channels and capillaries.

Light-band sensors

Picture Productfamily

These sensors generate over their complete width a homogenous light-band with uniform sensitivity for optical detection. Possible fields of application range from analog web guiding over non-contact limit switches up to dynamic counting windows or ejection controls.

Optoelectronic components

Picture Productfamily

With state-of-the-art technology, we manufacture precision microoptical component assemblies for our sensors. LEDs, photodiodies, phototransistors or laser diode modules with very extraordinary optical properties.

Fork sensors

Picture Productfamily

Optical fork sensors are all arrangements in which the electronic and optical components are mounted and precisely aligned in a fork-shaped metal housing. From standard through beam forks with visible red light, infrared or laser up to label detection sensors.

Frame sensors

Picture Productfamily

Frame sensors or otpical windows are densely packed through beams in a closed metal housing.

For detecting and counting fast-moving objects. With dynamic or static analysis. In fixed sizes or from a modular system.
