German CUENOT REGULATION sensor, CUENOT REGULATION model, CUENOT REGULATION price

CUENOT REGULATION sensors are measurement feedback devices that operate based on the optical principle of gratings. Grating scales are frequently used in the closed-loop servo systems of CNC machine tools for detecting linear or angular displacement. The measurement output signal is a digital pulse, characterized by a large detection range, high detection accuracy, and fast response speed. For example, in CNC machine tools, they are commonly used to detect the coordinates of tools and workpieces to observe and track tool path errors, thereby compensating for tool motion errors. Depending on the manufacturing method and optical principle, grating scales are divided into transmission gratings and reflection gratings.

CUENOT REGULATION sensor principle

Photoelectric sensors achieve control by converting changes in light intensity into changes in electrical signals. Generally, a photoelectric sensor consists of three parts: a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam toward the target; this beam usually originates from a semiconductor light source, such as a light-emitting diode (LED), laser diode, or infrared emitting diode. The light beam is emitted continuously or with modulated pulse width. The receiver comprises photodiodes, phototransistors, or photocells. Optical components such as lenses and apertures are installed in front of the receiver. Behind it is the detection circuit, which filters valid signals and processes them. In addition, structural components of photoelectric switches may include emitter plates and optical fibers.

CUENOT REGULATION sensor classification

1) Slot-type photoelectric sensor: Consists of a light emitter and a receiver mounted face-to-face on opposite sides of a slot. The emitter sends out infrared or visible light, which the receiver detects when unobstructed. When an object passes through the slot and blocks the light, the photoelectric switch activates, outputting a switching control signal to cut off or connect the load current, thus completing a control action. Due to structural constraints, the detection distance of slot switches is typically only a few centimeters. 2) Through-beam photoelectric sensor: Separating the emitter and receiver increases the detection distance. A through-beam photoelectric switch consists of one emitter and one receiver, also known as a opposed-mode photoelectric switch. The detection distance of through-beam switches can reach several meters to tens of meters. When using a through-beam switch, the emitter and receiver are installed on opposite sides of the object's path; when the object blocks the light path, the receiver activates and outputs a switching control signal. 3) Retro-reflective photoelectric switch: The emitter and receiver are housed in the same unit, with a reflector plate installed in front. It uses the principle of reflection for photoelectric control, known as a retro-reflective (or mirror-reflective) photoelectric switch. Under normal conditions, light emitted by the source is reflected back by the reflector plate and received by the receiver; once an object blocks the light path and the receiver no longer receives light, the photoelectric switch activates and outputs a switching control signal. 4) Diffuse-reflective photoelectric switch: The detection head of a diffuse-reflective photoelectric switch also contains an emitter and a receiver, but there is no reflector plate in front. Under normal conditions, the receiver does not detect the light emitted by the source. During detection, when an object passes through, it blocks the light and reflects part of it back; the receiver then detects the light signal and outputs a switching signal.

CUENOT REGULATION sensor application cases

1) Application of photoelectric sensors in laser weapons: Since photoelectric sensors are highly sensitive to infrared radiation, visible light, or both, they are particularly vulnerable to laser attacks. Furthermore, electronic systems and the sensors themselves are susceptible to interference from thermal noise and electromagnetic noise generated by lasers, preventing normal operation. Methods of laser weapon attacks on photoelectric sensors on the battlefield mainly include: using a laser beam of appropriate energy to "blind" the sensor, rendering it unable to detect or continue tracking already detected targets. Alternatively, if the sensor is guiding a weapon toward a target, blinding causes it to lose the target. In summary, as sensors play an increasingly important role on the battlefield while being highly susceptible to laser attacks, they have become the primary targets for low-energy laser weapons. 2) Application of photoelectric sensors in automatic meter reading systems: With the development of microelectronics, sensor technology, computer technology, and modern communications, photoelectric sensors can be used to develop automatic meter reading systems. The aluminum disk of an electricity meter rotates under torque generated by eddy currents and magnetic fields. Using a photoelectric sensor converts the number of rotations of the aluminum disk into pulse counts. For example, by partially blackening a section of the rotating shiny aluminum disk and pairing it with a reflective photoelectric emitter-receiver pair, pulses are generated at the blackened section as the disk rotates. The rotation count is sampled and converted into corresponding pulse counts, then sent via an optocoupler isolation circuit to the T0 port of the CPU for counting processing. Using optocoupler isolators effectively prevents interference signals from entering the microcomputer. Combined with other transmission methods, this forms an automatic meter reading system. 3) Application of photoelectric sensors in monitoring smoke and dust pollution: A photoelectric sensor is a small electronic device that detects changes in received light intensity, achieving control functions by converting these light intensity changes into electrical signal changes. Due to characteristics such as non-contact operation, fast response, and reliable performance, photoelectric sensors are widely used in industrial automation equipment and robotics. We can utilize these characteristics to detect smoke and dust conditions, meaning the strength of the photoelectric sensor's output signal reflects changes in flue gas turbidity. 4) Hygienic washdown-proof photoelectric sensors: Washdown-proof sensors provide extremely high reliability and ease of use while minimizing operating costs. Equipped with an IO-Link interface and the proTect+ sealing concept, which significantly extends service life, these two new sensors are suitable for demanding applications and represent an ideal solution for the food and beverage industry.
