German SCHNEIDER encoder SCHNEIDER model SCHNEIDER price

SCHNEIDER encoders are devices that encode signals (such as bitstreams) or data, converting them into signal forms suitable for communication, transmission, and storage. Encoders convert angular displacement or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to operating principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into periodic electrical signals, which are then converted into counting pulses, using the number of pulses to indicate the magnitude of displacement. Each position of an absolute encoder corresponds to a specific digital code, so its indication depends only on the start and end positions of the measurement, not on the intermediate process. The Encoder is a type of Sensor, mainly used to detect the speed, position, angle, distance, or count of mechanical motion. In addition to mechanical applications, many motor controls, such as servo motors, require encoders for the motor controller to perform commutation, speed, and position detection. Encoders can be classified as follows. Classification by code disk perforation method: 1) Incremental type: emits a pulse signal for each unit angle of rotation (some emit sine/cosine signals, which are then subdivided to chop out higher-frequency pulses), typically with A-phase, B-phase, and Z-phase outputs. The A-phase and B-phase outputs are pulses delayed by 1/4 cycle relative to each other; the direction of rotation can be distinguished based on the delay relationship, and 2x or 4x frequency multiplication can be achieved by using the rising and falling edges of the A-phase and B-phase signals. The Z-phase is a single-turn pulse, emitting one pulse per revolution. 2) Absolute type: for each reference angle within one revolution, it emits a unique binary value corresponding to that angle, allowing the recording and measurement of multiple positions via external revolution-counting devices. Classified by signal output type: voltage output, open-collector output, push-pull complementary output, and line-driver output. Classified by mechanical installation form: 1) Shaft type: shaft types can be further divided into clamping flange, synchronous flange, and servo mount types. 2) Hollow shaft type: hollow shaft types can be further divided into semi-hollow, fully hollow, and large-bore types. Classified by operating principle: photoelectric, magneto-electric, and contact brush types.

SCHNEIDER encoder classification

According to operating principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into periodic electrical signals, which are then converted into counting pulses, using the number of pulses to indicate the magnitude of displacement. Each position of an absolute encoder corresponds to a specific digital code, so its indication depends only on the start and end positions of the measurement, not on the intermediate process. Rotary incremental encoders output pulses during rotation, and their position is determined by counting equipment. When the encoder is stationary or power is lost, the position is retained in the internal memory of the counting equipment. Thus, after a power loss, the encoder must not move; when power is restored, pulses must not be lost due to interference during output, otherwise the zero point remembered by the counting equipment will shift. The amount of this shift is unknown and can only be detected when erroneous production results occur. The solution is to add a reference point; each time the encoder passes the reference point, the reference position corrects the memory position of the counting equipment. Before reaching the reference point, position accuracy cannot be guaranteed. Therefore, in industrial control, methods such as finding the reference point before each operation or homing at startup are used. For example, the positioning of printers and scanners uses the principle of incremental encoders; each time they are powered on, we hear a rattling sound as they search for the reference zero point before starting work.

SCHNEIDER encoder advantages

Small size, high bai precision, high inherent du resolution, non-contact and wear-free; the same zhi type can detect both angular displacement and, with the help of dao mechanical conversion devices, linear displacement; multi-turn photoelectric absolute encoders can detect linear displacement over considerable ranges (e.g., 25-bit multi-turn). Long service life, flexible installation, rich interface options, and reasonable pricing. Mature technology, widely applied domestically and internationally for many years. Disadvantages: high precision but requires higher protection for outdoor and harsh environment use; measuring linear displacement relies on mechanical conversion, requiring elimination of errors caused by mechanical backlash; difficult to overcome slip when detecting objects running on tracks. Advantages of magnetostatic absolute encoders: moderate size, direct measurement of linear displacement, absolute digital encoding, theoretically unlimited range; non-contact and wear-free, resistant to harsh environments, usable underwater up to 1000 meters; rich interface options and diverse measurement methods.

SCHNEIDER encoder technical specifications

HD encoders, also known as digital encoders, video encoders, HD video encoders, digital TV encoders, network video encoders, or digital video encoders, primarily function to digitally encode input digital audio-video signal sources (including HDMI signal sources, SD-SDI signal sources, and HD-SDI signal sources). Common encoding methods include MPEG-2, MPEG-4, H.264, and H.265. The encoded data is converted into TS stream data suitable for real-time transmission, which is then encapsulated in ASI or IP format for output to downstream equipment, such as IPQAM modulators, digital TV modulators, digital modulators, and DTMB modulators. The ASI format typically uses BNC interface output, while the IP format uses a 1000M Ethernet interface via RJ45. The IP data stream generally supports protocols such as TS/HLS/RTSP/FLV/RTMP/UDP/RTP/unicast/multicast.
