Photo Eyes

The wide variety of photoelectric sensors with their varying function characteristics solves almost every "detection problem".

  • Throughbeam - Throughbeam sensors consist of transmitter and receiver, which are contained in separate housings. The beam of the transmitter travels the whole light path only once.
  • Retro-Reflective - With retro-reflective sensors, the transmitter and receiver are combined in one housing. The beam of the transmitter meets the reflector and is redirected to the receiver of the sensor.
  • Retro-Reflective Sensors with Polarisation Filter - Highly reflective objects, such as mirror-like metal parts could cause switching errors. Those problems are avoided with polarised light filters.
  • Energetic Diffuse Reflection Scanners - The transmitter's beam is returned by the surface to be scanned itself. The scanning range of such a sensor is depending on its performance abilities and the reflection properties of the scanned surface.
  • Diffuse Reflection Light Scanners with Fading
  • Diffuse Reflection Scanners with Background Suppression

Color Sensors

This sensor type detects colors and compares them to a stored reference value. They are the right solution whenever the color of an object or marking can serve as a sorting or inspection criteria. Depending on the configuration and specified tolerance values of the system, the result is output as a switching signal.

Thanks to extensive configuration options and 1 or 4 color channels with individually adjustable color tolerance, this series can be used for fast processes with short response times.

If only one color channel is needed, this compact design is both a simple as well as a reliable solution.

This series with 3 color channels and the scan function for color gradients can be used flexibly in many areas of applications.

Products for Safety at Work

As one of the technology leaders in the area of optoelectronic safety sensors for industrial automation, we offer effective personnel protection devices in accordance with international safety standards.

Whether individual devices or optimally matched sets: in our extensive line of safety sensors, you will always find a suitable and efficient safety solution for point-of-operation, danger-zone and access guarding. Safety switches and magnetically coded safety systems are used for monitoring moveable safety guards, such as safety doors, sliding grilles or flaps. Opening the protective devices triggers an E-STOP command. Safety locking devices keep the protective doors locked, thereby preventing the inadmissible access of people until the guarded machine no longer poses a danger. Not until the safety sensors are efficiently and reliably integrated in the machine safety circuit can the topic of safety at work be implemented in such a way that the sensors do not interfere with the machine processes and yet still offer the best-possible protection.

Colour, Contrast & Luminescence Sensors

  • Contrast Scanner - Contrast scanners are high-resolution, energetic diffuse reflection scanners which differentiate between objects and/or object colours by grey values. This means that the brightness and shininess of the object or object colour strongly affect the measurement result. Contrast scanners have focusing optics and a special light-spot geometry.
  • Color Scanners - Colour sensors are diffuse reflection scanners which break down object colours into their different spectral components using a special combination of transmitter light. The different spectral composition of the received light is analysed by the sensor and compared with values stored previously in the sensor.
  • Luminescence Scanners - Luminescence scanners are energetic diffuse reflection scanners which illuminate luminescing materials by means of their special UV transmission light. The resulting visible light is detected by the luminescence sensor. Some of these luminescent materials are invisible and are available in a variety of solid and fluid forms.

Optical Distance & Light Section Sensors

These sensors function with red, infrared or laser light. Through the use of various receiving elements, such as CCD lines or a PSD element, the performance of the sensor can be adapted to the application or the given requirements. With these devices, various measurement techniques are used for distance determination. These include, among others: triangulation, phase measurement and the pulse propagation time technique. The accuracy of the measurement result is almost completely independent of differences in object colour. All systems can be adapted to a given application using configuration software.

Light section sensors work according to the triangulation principle. Using transmission optics a laser beam is expanded to a line and aimed at a measurement object. The light remitted by the object is monitored by a position sensitive planar detector (CMOS camera). Depending on the distance of the measurement object the laser line is projected to a different position on the planar detector. By means of this position the distance of the measurement object can be calculated. The sensor outputs 2D measurement values. It is possible to produce 3D profile data by including the movement of the measurement object.

Ultrasonic Distance Sensors

With these sensors, acoustic waves are transmitted and are reflected by the objects which are to be detected. The propagation time of the acoustic waves reflected back to the sensor is measured and the distance to the object calculated. This physical principle is particularly well suited for the detection of fluid-, powder-, and transparent media. The switching signals and distance information are available via digital or analog outputs. Application specific parameters can be set directly on the sensor using programming software.

  • Measurement ranges to 6000mm
  • Outputs:
    • 2 switching outputs
    • analogue current output
    • analogue voltage output
  • Operating principles:
    • HRTU models with background suppression
    • VRTU models with foreground and background suppression

Danfoss Starters

Danfoss VLT MCD 500 series soft starter is a total motor starting solution. Current transformers measure motor current and provide feedback for controlled motor ramp profiles. AAC, Adaptive Acceleration Control, automatically employs the best starting and stopping profile for the application. Adaptive Acceleration Control means that for each start and stop, the soft starter compares and adapts the process to the chosen profile fitting to the application.
