German POMPES JAPY sensors, POMPES JAPY models, POMPES JAPY prices

POMPES JAPY sensors precisely measure the actual displacement of the detected product by detecting the absolute position of a movable magnetic ring using internal non-contact measurement and control technology. The high precision and high reliability of these sensors have been widely applied in thousands of real-world cases. Since the movable magnetic ring used for position determination does not come into direct contact with the sensing element, the sensors can be used in extremely harsh industrial environments and are not easily affected by oil stains, solutions, dust, or other contaminants. In addition, the sensors use high-tech materials and advanced electronic processing technology, enabling them to operate in high-temperature, high-pressure, and high-vibration environments. The sensor output signal is an absolute displacement value; even if power is interrupted and reconnected, data is not lost, and there is no need to re-zero. Since the sensing element is non-contact, repeated detection causes no wear to the sensor, greatly improving detection reliability and service life.

POMPES JAPY sensor operating principle

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 usually comes 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 the pulse width is modulated. 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 include emitter plates and optical fibers.

POMPES JAPY sensor classification

1) Slot-type photoelectric sensor: A slot-type photoelectric sensor is formed by mounting a light emitter and a receiver on opposite sides of a slot, facing each other. 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 activates, 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-type switches is typically only a few centimeters. 2) Through-beam photoelectric sensor: Separating the emitter and receiver increases the sensing distance. A through-beam separated photoelectric switch, abbreviated as through-beam photoelectric switch, consists of one emitter and one receiver. The sensing distance of through-beam photoelectric switches can reach several meters or even tens of meters. When using a through-beam photoelectric switch, the emitter and receiver are installed on opposite sides of the object's path. As the object passes through and 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. This configuration, known as a retro-reflective (or mirror-reflective) photoelectric switch, utilizes the principle of reflection for photoelectric control. Under normal conditions, the light emitted by the emitter is reflected by the reflector plate and received by the receiver. Once an object blocks the light path and the receiver no longer detects light, the photoelectric switch activates 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 through, it blocks the light and reflects part of it back to the receiver. Upon receiving the light signal, the switch outputs a switching signal.

POMPES JAPY sensor application cases

1) Photoelectric sensors in laser weapons: Because 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. Laser weapon attacks on photoelectric sensors on the battlefield mainly occur in the following ways: 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 it causes loss of the target. In summary, because sensors play an increasingly important role on the battlefield and are vulnerable to laser attacks, they have become the preferred targets for low-energy laser weapons. 2) 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 photoelectric sensors converts the number of rotations of the aluminum disk into pulse counts. For example, partially blackening a rotating shiny aluminum disk and pairing it with a reflective photoelectric emitter-receiver pair generates pulses at the blackened sections 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) Photoelectric sensors for monitoring smoke and dust pollution: Photoelectric sensors are small electronic devices that detect changes in received light intensity, achieving control functions by converting 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 leverage 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-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 ideal solutions for the food and beverage industry.
