German aktif inst sensor aktif inst model aktif inst price

aktif inst sensors are sensors that measure the operating speed of the measured object and convert it into an output signal. Speed sensors include linear speed sensors and rotational speed sensors. With the development of technology, traditional measurement equipment can no longer meet current needs and is gradually being phased out, while laser speed sensors are widely used and play an important role in product manufacturing. By connecting to a computer, they enable automated and intelligent measurement and control of the measured object. This is the product of the combination of modern measurement technology and computer technology.

aktif inst 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; the light source is typically a semiconductor 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 consists of photodiodes, phototransistors, or photocells. Optical components such as lenses and apertures are mounted in front of the receiver. Behind it is the detection circuit, which filters the valid signal and processes it. In addition, structural components of photoelectric switches may include emitter plates and optical fibers.

aktif inst sensor classification

1) Slot-type photoelectric sensor: A slot-type photoelectric sensor is formed by mounting a light emitter and a receiver facing each other on opposite sides of a slot. The emitter emits infrared or visible light, which the receiver detects when unobstructed. When an object passes through the slot and blocks the light, the photoelectric switch actuates, outputting a switching control signal to interrupt or connect the load current, thereby completing a control action. Due to structural constraints, the sensing distance of slot switches is typically only a few centimeters. 2) Through-beam photoelectric sensor: Separating the emitter and receiver increases the sensing distance. A through-beam photoelectric switch consists of one emitter and one receiver, also known as a through-beam photoelectric switch. The sensing distance of through-beam photoelectric switches can reach several meters to tens of meters. When using a through-beam photoelectric switch, the emitter and receiver are installed on opposite sides of the object's path. When the object passes and blocks the light path, the receiver actuates 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 to perform photoelectric control, known as a retro-reflective (or mirror-reflective) photoelectric switch. Under normal conditions, the light emitted by the emitter is reflected by the reflector plate back to the receiver. Once an object blocks the light path and the receiver no longer receives light, the photoelectric switch actuates and outputs a switching control signal. 4) Diffuse-reflective photoelectric switch: The sensing 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 emitter. During detection, when an object passes, it blocks the light and reflects part of it back; the receiver then detects the light signal and outputs a switching signal.

aktif inst sensor application cases

1) Application of photoelectric sensors in laser weapons: Because photoelectric sensors are highly sensitive to infrared radiation, visible light, or both, they are more likely to become targets of laser attacks. Furthermore, electronic systems and the sensors themselves are highly 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 will cause it to lose the target. In summary, because sensors play an increasingly important role on the battlefield and are vulnerable to laser attacks, they have become the primary targets of 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 rotations are 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 changes in light intensity into changes in electrical signals. Due to characteristics such as non-contact operation, fast response, and reliable performance, photoelectric sensors are widely used in industrial automation devices and robotics. We can utilize the characteristics of photoelectric sensors to detect smoke and dust conditions; thus, the strength of the output signal from the photoelectric sensor reflects changes in flue gas turbidity. 4) Hygienic washdown-resistant photoelectric sensors: Washdown-resistant sensors provide extremely high reliability and ease of use while minimizing operating costs. Equipped with IO-Link interfaces and the proTect+ sealing concept, which significantly extends service life, these two new sensors are suitable for demanding applications and are an ideal solution for the food and beverage industry.
