Sensors in this category can detect or count objects without contact, measure distances, and detect colors, gloss or luminescence using light. The additional connection of special fiber-optic cables permits their use in extreme conditions such as cold, heat or limited space.
In the case of reflex sensors, the emitter and the receiver are located in the same housing. The emitted light is reflected and recorded by the object, the evaluation is carried out according to the energy principle or via angle measurement. Objects can be detected with or without defined background.
Fork sensors work with either red light or a collimated laser light beam. The emitter and receiver are arranged opposite each other in a plastic or stainless steel housing. Fork sensors with collimated laser light beam are particularly effective for detecting the smallest objects or clear glass.
Color sensors analyze the finest color nuances in automated processes at high speeds and select colored objects based on previously defined reference colors. Thanks to the pulsed white light, the sensors are insensitive to ambient light.
Distance sensors are suitable for the detection, differentiation and measurement of objects by means of ultrasound. Different operating modes, such as synchronous, multiplex or through beam mode, can be set via the display or centrally via IO-Link, and different output variants and designs enable a wide range of possible applications.
Fluid sensors detect parameters such as pressure, flow, temperature or fill level in liquid or gaseous media. The range of products includes models with one or two measuring functions, with an integrated analysis module and display, in stainless steel or plastic, and with IO-Link or two analog switch outputs.
Pressure sensors with integrated analysis module measure pressure for hydraulics, pneumatics and process technology. The weFlux² series, with which pressure and temperature are measured simultaneously, also has IO-Link. This allows parameter data to be configured and transmitted.
Flow sensors operate according to the calorimetric principle and can be mounted independently of the current direction. weFlux² series models combine flow and temperature measurement; parameter settings or data transfer can be carried out via IO-Link.
Temperature sensors measure and monitor liquid and gaseous media with high accuracy and fast response times. Modular designs and process connections allow them to be used individually. The weFlux² series features IO-Link for setting parameters.
