Sensors
Our sensors can be found in almost every application in automation technology. They are used in piloting, controlling, positioning and checking processes. Thanks to their robust design, excellent sensory characteristics and easy use, the sensors offer high availability and top performance data.
In order to provide solutions to the multitude of industrial tasks, Using a wide variation of physical principles in our sensors. The application determines whether light or an electric field or sound waves are used as the measuring medium – each principle has its strengths.
Our concept: Speed combined with innovation, quality and customer awareness.
The Product Range:

F40 Series 
The product series with the advantages of the almost standardised cubic housing:
the sensor head can be rotated axially on the fixing flange, by 360° in 8 steps. The connector plug can also be rotated by 90°. This combination makes it possible to
set the light emission on 5 of the 6 possible sides of the cube. 4 further intermediary settings are possible. A special highlight is the version which detects glass.

Distance Measurement
We cover the complete measuring range from several millimetres to very large distances (metres) thanks to a wide range of sensors. Different technical solutions enable utmost measuring accuracy from the mm-range up to 250 m.
Vision Sensors & Systems
Whether the task involves position monitoring, reading barcodes and data matrix codes or accurately detecting colour: the FA45 vision sensor is the solution for a wide range of applications which were previously impossible without complex and expensive image processing systems. Foolproof, reliable and economic, the FA45 is a pre-configured vision sensor adapted to the respective application, which does not require time-consuming training. “Plug and play“ without experience in image processing
Miniaturisation of dimensions with built-in intelligence
Reliable even in extreme ambient condition and all that at an unbeatable price ...
For more demanding applications, we offer our EYESIGHT image processing solution. Based on the same hardware platform, EYESIGHT offers all the advantages of the FA45 vision sensor and a full range of lenses, lighting and connectivity.
The intuitive development environment includes every necessary function
and assists you in the programming of demanding solutions.
Colour, Contrast & Mark Detection
Whilst conventional colour sensors need three superimposed primary colours for detection purposes, our FT50 C and FT20 WT sensors operate with white light and offer the right solution for every application: the FT50 C is thus available e.g. with 3 signal outputs or just one signal output with control cables and a bus compatible RS 485 interface. The FL 64-1-C colour sensor is a DIN rail sensor with a fibre optic connection. It is simply clicked onto a DIN rail. The fibre optic head with a diameter of 6 mm can detect colour reliably even in cramped conditions. For contrast detection, we have the sensors FT 82, FT 20 RL and FT 20 WT.

Sensors for Fibre-optics
Systems using fibre-optics are given preference in applications with limited installation space. Combined with the right fibre-optic, our sensors provide the perfect solution even in harsh environments and high ambient temperatures. The FL 70 R-D is our high-end sensor for fibre-optics with a 4 digit display. It is characterised by simple settings and many additional functions, e.g. fine adjustment of the switch point, inversion of the switch output, adjustment of accuracy and speed, window programming, time functions and tamper-proof protection. The display is always clearly visible thanks to a 180° rotatable screen. FL 70 R sensor is also available with an analogue output as FL 70 RA-D, or without a display - for simpler applications.
For particularly long switching distances or harsh environments, we recommend our cylindrical sensors FMS 18 und FMS 30 for use with particularly robust glass fibre-optics.
Fibre-optics
Fibre-optic sensors are only ever as good as the combination of fibre-optic and sensor. The right combination is decisive for optimum function. You can find the right fibre-optic for your application in our brochure "Fibre-optics & Fibre-optic sensors".
Fork Sensors
The main feature of our fork sensors is their reliability with utmost accuracy. Even very small objects are reliably detected. High switching frequencies enable the detection of moving objects. All versions have a plug connection and use visible red light.
Metal versions: Simple and robust designReversible N.O./N.C.
3-pin connection
Plastic fork sensors:
With NPN or PNP, 3- or 4-pin connections
Dynamic teach-in
Setting to moving objects is possible
Output signal LEDs visible from all sides
Numerous mounting possibilities(e.g. dovetail)
Optical Windows
A decisive feature for the reliable detection of small objects is the resolution of the beam grid and its time response. The resolution of our optical windows guarantees a reliable detection of parts as small as 0.8 mm. Deadlocks can be avoided thanks to the dynamic signal evaluation and parts can be detected, e.g. through transparent tubes. The adjustable length of the output signal (from 10 to 300 ms) enables a maximum degree of compatibility with your PLC.

Available window sizes: 40, 80, 120 mm
Ultrasonic Sensors 
All the ultrasonic sensors from the U 12, U 18 and U 30 series are cylindrical sensors with a robust metal housing. Working ranges of up to 6 m can be achieved. With the miniature U20 series, we achieve scanning ranges of up to 700 mm. These sensors are very easy to programme via teach-in.
Inductive Sensors
We offer a wide range of different inductive sensors. Besides standard sensors, you can find inductive sensors with 3 times the switching distance. This increased switching distance enables considerably greater availability in harsh industrial applications.
Capacitive Sensors
All capacitive sensors are fitted in a robust cylindrical housing. Flush and Non-Flush versions means that the Non-flush sensor head emits a spherical electric field directly from the sides enabling considerably greater measuring distances in small robust packaging.
