Forked photoelectric sensors
Fork sensors are measuring devices used to detect the movement and speed of objects. They consist of a fork with a transmitter and receiver facing each other.
The fork emits a light beam which is interrupted by the object to be measured. When the light beam is interrupted, the receiver generates an electrical signal that is processed by an electronic circuit. The processing of the signal enables the speed and/or position of the object to be measured.
Fork sensors are used in a wide range of applications, including industrial, commercial and leisure. They can measure the speed of conveyor belts or the movement of machine parts. Fork sensors can also be used to automatically control plant or machinery by transmitting the signal to a control unit.
Modern fork sensors often use digital displays and can be linked to other systems, such as an automatic control system, to optimise the production process and increase efficiency.
Fork sensors are a simple and effective method of measuring movement and speed and can be used in many applications.

Fork light barriers are offered with different measuring principles. These are:
Capacitive
Optical
Laser
Ultrasonic
Light band
Laser forked photoelectric sensors enable the detection of the smallest parts and offer high resolution and very good immunity to ambient light.
Light/dark switching
If the light beam between the transmitter and receiver of the throughbeam photoelectric sensor is interrupted and switches the photoelectric sensor, the function is dark switching. Accordingly, the photoelectric sensor is light-switching when the receiver receives light and then switches. Sensors are also offered that can be switched between light and dark.
In addition to point light sources, forked barriers are also offered that emit a band of light or ultrasonic waves. These light band fork sensors are particularly suitable for detecting faults in wires and threads.
The forked light barriers are characterized, among other things, by short response times and high resolution. Typical applications of forked photoelectric sensors include: Detection of small objects, speed measurement, ejection control, positioning tasks, counting of objects.

What are fork light barriers and how do they work?
Fork light barriers are optoelectronic sensors that are used to detect objects. They consist of a transmitter unit that emits infrared light and a receiver unit that detects the reflected light.
The function of a fork light barrier is based on the principle of interrupting the light beam. The transmitter unit generates a light beam that is detected by the receiver unit as long as no object interrupts the beam. If an object enters the area between the transmitter unit and the receiver unit and blocks the light beam, no more light is detected by the receiver unit. This leads to a change in the electrical signal generated by the receiver unit.
This change in the signal can then be recognized by a suitable evaluation system and converted into a corresponding signal. This signal can be used, for example, to control a process, to detect presence or to detect movement.
Fork light barriers are used in various applications, e.g. in automation technology, the packaging industry, conveyor technology, robotics and many other areas in which the precise detection of objects is required.
