XECRO switch German XECRO model XECRO price

XECRO switches are the direct source of information for the entire machine vision system, mainly consisting of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of a vision sensor is to acquire the raw images that the machine vision system needs to process. Image sensors can use laser scanners, line-scan and area-scan CCD cameras or TV cameras, as well as the latest digital cameras.

XECRO switch classification

1) Potentiometric displacement switch, converting mechanical displacement into resistance or voltage output with a linear or arbitrary functional relationship. Standard linear potentiometers and rotary potentiometers can be used as linear displacement and angular displacement switches, respectively. However, potentiometers designed for displacement measurement require a defined relationship between displacement change and resistance change. The movable wiper of the potentiometric displacement switch is connected to the measured object. The displacement of the object causes a resistance change at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while an increase or decrease in resistance indicates the direction of displacement. Typically, a supply voltage is applied to the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps corresponding to the turn-to-turn resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement switch is used as a displacement feedback element in a servo system, excessive step voltages can cause system oscillation. Therefore, the resistance per turn should be minimized during potentiometer manufacturing. Another major disadvantage of potentiometric switches is their susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost. 2) Magnetostrictive displacement switches precisely detect the absolute position of a moving magnetic ring using non-contact measurement technology to determine the actual displacement of the product under test; the high precision and high reliability of these switches have been widely applied in thousands of practical cases. Since the moving magnetic ring that determines the position does not come into direct contact with the sensitive element, the switch can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust, or other contaminants, with an IP protection rating of IP67 or higher. In addition, the switch uses advanced materials and electronic processing technology, allowing it to operate in high-temperature, high-pressure, and high-vibration environments. The switch output signal is an absolute displacement value; even if the power is interrupted and reconnected, data is not lost, and re-zeroing is not required. Since the sensitive element is non-contact, repeated detection does not cause any wear on the switch, significantly improving detection reliability and service life. Magnetostrictive displacement switches accurately measure position by utilizing the magnetostrictive principle, where the intersection of two different magnetic fields generates a strain pulse signal. The measuring element is a waveguide, and the sensitive element inside the waveguide is made of special magnetostrictive material. The measurement process involves generating a current pulse in the electronics housing of the switch, which travels through the waveguide, creating a circular magnetic field around it. When this magnetic field intersects with the magnetic field generated by the moving magnetic ring sleeved on the waveguide (which changes with position), a strain mechanical wave pulse signal is generated within the waveguide due to the magnetostrictive effect. This strain mechanical wave pulse signal travels at a fixed speed of sound and is quickly detected by the electronics housing. Since the transmission time of this strain mechanical wave pulse signal within the waveguide is proportional to the distance between the moving magnetic ring and the electronics housing, measuring the time allows for highly precise determination of this distance. Because the output signal is a true absolute value, rather than a proportional or amplified signal, there is no signal drift or value variation, and regular recalibration is not required. Magnetostrictive displacement switches are high-precision, long-stroke absolute position measurement displacement switches manufactured based on the magnetostrictive principle. They employ a non-contact measurement method; since the moving magnetic ring used for measurement does not come into direct contact with the switch itself, friction and wear are avoided, resulting in long service life, strong environmental adaptability, high reliability, good safety, and ease of system automation. Even in harsh industrial environments, they can operate normally. Furthermore, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement.

XECRO switch application areas

Widely applicable for level measurement and control of various liquid tanks in industries such as petroleum, chemical, water conservancy, pharmaceutical, food, and beverage, as well as aerospace refueling systems, automotive refueling systems, diesel refueling systems, various hydraulic tanks, hydrological monitoring, and water treatment. Magnetostrictive displacement switches are high-precision, long-stroke absolute position measurement displacement switches manufactured based on the magnetostrictive principle. They employ an internal non-contact measurement method; since the moving magnetic ring used for measurement does not come into direct contact with the switch itself, friction and wear are avoided, resulting in long service life, strong environmental adaptability, high reliability, good safety, and ease of system automation. Even in harsh industrial environments (such as those prone to oil stains, dust, or other contamination), they can operate normally [01]. In addition, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement. Their stroke can reach 3 meters or longer, with a nominal accuracy of 0.05% F·S, and for strokes over 1 meters, the accuracy can reach 0.02% F, S, with repeatability up to 0.002% F·S, making them widely used in petrochemical, aerospace, electric power, water conservancy, and other industries.
