Optical sensors

Optical sensors and inductive proximity switches from Kistler guarantee product quality in stamping and forming processes.

Kistler develops and manufactures high-caliber optical sensors, also known as optosensors, and inductive proximity switches that deliver reliable process control and monitoring. Technical equipment, systems and structures that function safely and reliably are the key to dependable and efficient production processes – and fit-for-purpose monitoring systems open the way to major improvements in reliability as well as efficiency. Features such as feed, ejection and double-sheet control (tool immersion depth measurement) guarantee product quality in punching and forming processes. Customized for each application, these products ensure high levels of reliability and cost-effectiveness in the manufacturing process: malfunctions are detected at an early stage, so tool breakages and the costly damage they cause are avoided.

Frequently asked questions

What happens if the fork light barrier / light barrier becomes dirty?
In case that the fork light barrier / light barrier becomes dirty, for example by deposits such as oil or dirt particles on the lenses / glasses in front of the transmitter or receiver, the light transmission will become impaired. This changes the switching threshold, i.e. the response limit at which a switching operation is triggered.
Definition of resolution? Meaning of resolution and accuracy of optical sensors? What is resolution? What is the resolution of an optical sensor?
The resolution of an optical sensor is defined as the smallest part size / object size that can be reliably detected by a sensor at the highest sensitivity setting.
What is the switching frequency? What is the switching frequency of a light barrier? What is the switching frequency of an optical sensor? What does the switching frequency mean?
The switching frequency of a light barrier / optical sensor is defined as the speed of optical sensors. The switching frequency is the maximum possible number of switching operations / switching sequences per second with which a sensor can reliably detect an object.
