JCI REGELUNGSTECHNIK sensors are devices that convert magnetic signals into electrical signals. By utilizing the transformation relationship between magnetic quantities and other physical quantities, with the magnetic field as a medium, they can also convert signals of other non-electrical physical quantities into electrical signals. There are two driving methods: one is driven by a permanent magnet, and the other is driven by an electromagnetic coil. The former is mostly used for detection; for example, if a moving part is made of a magnet, it will attract and emit a signal once it approaches the magnetic induction sensor. The latter is mostly used for control; if the electromagnetic coil is energized, the contacts will attract. Replacing limit switches that rely on collision contact with magnetic induction sensors can improve system reliability and service life; therefore, they are often used in programmable logic controllers as signaling devices for position arrival.

JCI REGELUNGSTECHNIK sensor principles

Photoelectric sensors achieve control by converting changes in light intensity into changes in electrical signals. Generally, photoelectric sensors consist of three parts: a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam toward the target. The emitted light beam generally comes from semiconductor light sources, such as light-emitting diodes (LED), laser diodes, and infrared emitting diodes. The light beam is emitted continuously, or the pulse width is changed. The receiver consists of photodiodes, phototransistors, and photocells. Optical components such as lenses and apertures are installed in front of the receiver. Behind it is the detection circuit, which filters out valid signals and applies them. In addition, the structural components of photoelectric switches also include emitter plates and optical fibers.

JCI REGELUNGSTECHNIK sensor classification

1) Slot-type photoelectric sensors: A slot-type photoelectric sensor is formed by mounting a light emitter and a receiver face-to-face on both sides of a slot. The emitter can emit infrared or visible light, and the light receiver can receive the light when there is no obstruction. However, when the detected object passes through the slot, the light is blocked, causing the photoelectric switch to actuate and output a switching control signal, cutting off or connecting the load current, thereby completing a control action. Due to limitations of the overall structure, the detection distance of slot-type switches is generally only a few centimeters. 2) Through-beam photoelectric sensors: Separating the emitter and the receiver increases the detection distance. A through-beam separated photoelectric switch, abbreviated as a through-beam photoelectric switch, consists of one emitter and one receiver. The detection distance of through-beam photoelectric switches can reach several meters or even tens of meters. When using through-beam photoelectric switches, install the emitter and receiver on opposite sides of the path through which the detected object passes. When the object passes, it blocks the light path, causing the receiver to actuate and output a switching control signal. 3) Retro-reflective photoelectric switches: The emitter and receiver are housed in the same unit, with a reflector plate installed in front. This utilizes the principle of reflection to achieve photoelectric control, known as a retro-reflective (or mirror-reflective) photoelectric switch. Under normal conditions, the light emitted by the emitter is reflected back by the reflector plate and received by the receiver. Once the detected 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 switches: 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 cannot detect the light emitted by the emitter. During detection, when the object passes, it blocks the light and reflects part of it back. The receiver then receives the light signal and outputs a switching signal.

JCI REGELUNGSTECHNIK sensor application cases

1) Application of photoelectric sensors in laser weapons: Since photoelectric sensors are particularly sensitive to infrared radiation, visible light, or both, they are more likely to become targets of laser attacks. In addition, electronic systems and the sensors themselves are highly susceptible to interference from thermal noise and electromagnetic noise generated by lasers, preventing normal operation. The main ways laser weapons on the battlefield attack photoelectric sensors include: using a laser beam of appropriate energy to "blind" the sensor, rendering it unable to detect or continue tracking already detected targets. Or, if the sensor is guiding a weapon toward a target, blinding will cause it to lose the target. In summary, since sensors play an increasingly important role on the battlefield and are vulnerable to laser attacks, they have become the preferred 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 technology, photoelectric sensors can be used to develop automatic meter reading systems. The aluminum disk of an electricity meter rotates under the torque generated by eddy currents and magnetic fields. Using photoelectric sensors converts the number of rotations of the aluminum disk into pulse counts. For example, by partially blackening a rotating shiny aluminum disk and pairing it with a reflective photoelectric emitter-receiver pair, pulses are generated at the blackened areas as the disk rotates. The number of rotations 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: Photoelectric sensors are small electronic devices that can detect 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 robots. We can utilize the characteristics of photoelectric sensors to detect smoke and dust conditions, so 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 comfort 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 harsh application environments and are ideal solutions for the food and beverage industry.
