V4NCSET7 switch, German BURGESS model V4NCSET7 price

V4NCSET7 switch precisely measures the actual displacement of the detected product by detecting the absolute position of the movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of this switch have been widely applied in thousands of practical cases. Since the movable magnetic ring used for position determination and the sensitive element do not come into direct contact, the switch can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust, or other contaminants. In addition, the switch uses high-tech materials and advanced electronic processing technology, so it can be used in high-temperature, high-pressure, and high-vibration environments. The switch output signal is the absolute displacement value; even if the power is interrupted and reconnected, data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, continuous repeated detection will not cause any wear to the switch, which can greatly improve detection reliability and service life.

V4NCSET7 switch classification

1) Laser speed measurement: With the rise of precision manufacturing and the demand for cost savings, non-contact speed switches are gradually replacing contact speed switches. Currently, the most common and high-precision non-contact laser speed switch on the market is the ZLS-Px aberration speed switch. The aberration speed switch has two ports: one emission port that emits a LED light source, and one high-speed photography port that achieves CCD area high-speed imaging comparison. By comparing images at two points in time within an extremely short period, the distance the object moves is determined, and combined with the internal algorithm of the switch, the speed of the object is output in real time. As shown in the figure, (1) is the LED light emission port, (2) is the camera reception port, (3) and (4) are terminal blocks, and (5) are fixing screw holes. (1) The LED light emission port emits laser light toward the object under test, which reflects to the (2) camera reception port. After receiving the signal, it is transmitted to the signal processor, which calculates the speed using an algorithm. The ZLS-Px aberration speed switch can simultaneously measure speed and length in two directions. It can not only detect whether the object under test has stopped but also detect its direction of motion. Fix the switch on a stable bracket to ensure that the rotating object does not produce excessive vibration during rotation, thereby allowing measurement of the rotation angle and rotational speed of the object under test. 2) Radar speed measurement: Traditional speed measurement mostly involves rotary motion speed measurement and linear motion speed measurement. However, there are many irregular speed measurements in industrial automation, such as athlete speed measurement, traffic vehicle speed measurement, and golf ball speed measurement. Radar speed switches can meet these requirements.

V4NCSET7 switch principle

A transmissive speed sensor consists of a slotted or perforated disk, a light source, and a phototube. When the disk rotates with the shaft under test, light can only reach the phototube through the holes or slots. When the phototube is illuminated, its reverse resistance is very low, and it outputs an electrical pulse signal. When the light source is blocked by the disk, the reverse resistance of the phototube is very high, and there is no signal output at the output terminal. Thus, based on the number of holes or slots on the disk, the rotational speed of the shaft under test can be measured. The number of holes or slots on the disk is usually set to sixty, so that for each revolution of the shaft under test, the photoelectric converter outputs 60 pulse signals. If the time base signal of the electronic counter is set to 1s, the rotational speed of the shaft under test can be read directly. The principle of a reflective speed sensor is the same as that of a transmissive one; it converts changes in received light into changes in electrical signals via a phototube, but it obtains pulse signals through light reflection, typically by adhering reflective material to the measurement area on the shaft under test to form a reflective surface. Commonly used reflective materials are special speed-measuring reflective paper tapes (adhesive tapes); aluminum foil or other reflective materials can also be used as substitutes; sometimes white paint can be applied to the measurement area to serve as a reflective surface. The emitter and the reflecting surface must be properly configured, typically, the distance between them is 5-15M. When the measured shaft rotates, the photoelectric element receives pulsating light, and outputs the corresponding electrical signal to the electronic counter, thereby measuring the rotational speed of the measured shaft. The waveform of the output signal from the photoelectric speed switch is relatively regular, close to a standard square wave, with almost no interference signals generated. However, vibration in through-beam types reduces the service life of the light source, so they are not suitable for use under conditions with strong vibration. Reflective types have no mechanical connection with the measured shaft, making them convenient to use.

V4NCSET7 switch industry applications

1) Modern cars are generally equipped with engine control, autonomous driving, ABS, TRC, automatic door locking, active suspension, guidance systems, electronic instruments, and other devices, all of which require vehicle speed signals. Therefore, the accuracy and stability of the output signal from the speed measurement switch will have a significant impact on these control units. Automotive speed switches mostly adopt a Hall-effect structure. A Hall speed switch is a magnetoelectric switch based on the Hall effect, featuring high sensitivity to magnetic fields, stable output signals, high frequency response, strong anti-electromagnetic interference capability, simple structure, and ease of use. It mainly consists of permanent magnets with a specific number of pole pairs (generally 4 or 8 pairs), Hall elements, a rotating mechanism, and input/output connectors. Its working principle is that when the rotating mechanism of the switch rotates under external drive, it drives the permanent magnet to rotate, causing periodic changes in the magnetic field passing through the Hall element. This causes the output voltage of the Hall element to change, which is processed by subsequent circuits to form a stable pulse voltage signal as the output of the speed switch. The main electrical technical parameters of Hall-structure speed switches include: output signal high voltage, low voltage, duty cycle, period, rise time, fall time, and number of pulses per cycle. To ensure product performance and reliability, these parameters must be quantitatively tested before leaving the factory. Test systems featuring integration and intelligence, efficient automatic measurement, software calculation, and graphical or tabular display of test results are increasingly favored by automotive speed switch manufacturers. A comprehensive testing device developed for performance measurement of commonly used Hall-effect vehicle speed switches. Considering cost, the high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed switch, and software control is used to calculate and graphically display the acquired data. The completed testing device offers advantages such as high testing precision, reliable data communication, a user-friendly graphical interface, strong anti-interference capability, simple and intuitive detection process, and low system development cost. It has good market promotion potential, so speed switches will have huge application prospects in vehicle speed detection. 2) Speed switches for belt conveyors use Hall switches, which are switches that utilize the Hall effect to achieve magnetoelectric conversion. The Hall effect was discovered in 1879 and has a development history of more than 100 years. However, its application gained attention and widespread use in the 50s of this century due to the rapid development of microelectronics, leading to the continuous development of various Hall elements. China began to increase research on Hall elements in the 20s of the 70th century. After nearly several decades of research and development, it is now possible to produce Hall elements with various performances, such as ordinary type, high-sensitivity type, low-temperature-coefficient type, temperature/magnetic measurement type, and switching type. Due to the characteristics of Hall switches, such as high sensitivity, good linearity, high stability, small size, and high-temperature resistance, they have been widely used in various industrial fields, including non-electrical quantity measurement and automatic control, computer devices, and modern military technology.
