German TEKEL encoder TEKEL model TEKEL price

TEKEL 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 referred to as a code disk, and the latter as a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to the working 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. In absolute encoders, each position 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 in the following ways. Classification by code disk slotting method: 1) Incremental type: emits a pulse signal for every 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 of a 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 working principle: photoelectric, magneto-electric, and contact brush types.

TEKEL encoder installation and usage

Mechanical installation of absolute rotary encoders includes high-speed end installation, low-speed end installation, and auxiliary mechanical device installation. High-speed end installation: installed at the drive motor shaft end (or gear connection). The advantage of this method is high resolution; since multi-turn encoders have 4096 turns, if the motor revolutions are within this range, the full range can be utilized to improve resolution. The disadvantage is that when the moving object passes through reduction gears, there is gear backlash error during reciprocating motion. It is generally used for unidirectional high-precision control positioning, such as roll gap control in steel rolling. Additionally, if the encoder is directly installed on the high-speed end, motor vibration must be minimal, otherwise the encoder is prone to damage. Low-speed end installation: installed after the reduction gear, such as at the shaft end of a hoist wire rope drum or the last stage of the reduction gear shaft. This method eliminates gear backlash, provides more direct measurement and higher accuracy. This method is generally used for long-distance positioning measurements, such as various lifting equipment and feed cart positioning. Auxiliary mechanical installation: common methods include rack and pinion, chain and belt, friction wheels, and rope retraction mechanisms.

TEKEL 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 a considerable range (such as 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: while precise, they impose higher protection requirements for outdoor and harsh environment use; measuring linear displacement relies on mechanical conversion devices, requiring the elimination of errors caused by mechanical backlash; it is difficult to overcome slip when detecting objects running on tracks. Advantages of magnetostatic grating 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.

TEKEL 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 signals are encoded into TS stream data suitable for real-time transmission, and the data stream is then encapsulated in ASI format 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 with RJ45. The IP data stream generally supports protocols such as TS/HLS/RTSP/FLV/RTMP/UDP/RTP/unicast/multicast.
