Three technologies that get to the point

1) Laser triangulation

Triangulation is based on distance measurement through angle calculation. The sensor projects a light spot onto the object to be detected. The light reflected from the object hits the receiver array of the sensor at an angle that depends on the distance. The distance of the object is determined based on the position of the light spot on the receiver element.

2) Time-of-flight process

In time-of-flight measurement (optical time-of-flight), the distance between the sensor and object is derived from the measured time, which passes between when the sensor emits the light pulse (laser diode, LED) and the reflection returns back to the receiver.

3) Ultrasonic time-of-flight process

With the time-of-flight measurement with ultrasonics, the sensor emits an acoustic pulse that is reflected by the object being detected. The time required for the pulse to go from the sensor to the object and come back again is measured and evaluated and converted into the respective distance.

Future-oriented interfaces – always correctly connected

Sub sub head: 1) IO-Link

IO-Link offers new options for point-to-point communication between the system control and field level. Simple sensors and actuators become active process participants in an end-to-end automation network.

As senders, they report statuses to the controller via a master; as receivers they receive and process signals in reverse. This optimises processes throughout the entire supply chain.

Ethernet and fieldbuses

With Ethernet and fieldbuses, all participating sensors and actuators can communicate with the system control as a sensor network. Depending on the interface type, different hierarchies and arrangements of the devices involved – so-called topologies – are available.

Ethernet and fieldbuses enable the processing of large amounts of data, the transmission of sensor data in real time and its direct integration into IT systems and clouds.


Serial interfaces are used for direct data transmission between a controller and a sensor or actuator.

During communication, all bits are transmitted individually and successively via a point-to-point connection.

The main advantages of serial interfaces are the low technical complexity and independence from the system setup.
