German TR-Electronic encoder TR-Electronic model TR-Electronic price

TR-Electronic encoders are devices used to measure rotational speed and, when combined with PWM technology, enable rapid speed regulation. Optical rotary encoders convert mechanical quantities such as angular displacement and angular velocity of the output shaft into corresponding electrical pulses via photoelectric conversion, outputting them as digital signals (REP). They are available in single-channel output and dual-channel output types. Key technical parameters include pulses per revolution (ranging from tens to thousands) and supply voltage. Single-channel output means the rotary encoder outputs one set of pulses, while dual-channel output rotary encoders output two sets of pulses with a A/B phase difference of 90 degrees. Using these two sets of pulses allows not only speed measurement but also determination of the direction of rotation. Based on signal output type, they are classified as: voltage output, open-collector output, push-pull complementary output, and line-driver output.

TR-Electronic encoder accuracy

(1) Uses a code disk with 8421 coding. Although relatively simple, it imposes strict requirements on code disk manufacturing and installation; otherwise, erroneous codes may occur. When the brush transitions from binary code 0111 to 1000, the value should change from 7 to 8. However, if the brushes do not enter the conductive areas simultaneously, any decimal number between 8 and 15 may appear, resulting in the aforementioned non-single-valued error. One method to resolve this issue is to use a cyclic code disk. Due to the characteristics of cyclic codes, even if manufacturing and installation are inaccurate, the maximum error is limited to one bit in the least significant position. Therefore, cyclic code disks offer higher accuracy than 8421 code disks. (2) Scanning method. The scanning method includes V scanning, U scanning, and M scanning. A brush is installed on the least significant bit track, while two brushes are installed on each of the other bit tracks: one brush is positioned ahead of the measured position, called the leading brush; the other is placed behind the measured position, called the lagging brush. If the incremental width of the effective bit on the least significant bit track is z, then the distances corresponding to the brushes for each bit are 1x, 2x, 4x, 8x, etc. Thus, at each definite position, the output level of the least significant bit brush reflects its true value. Since there are two brushes for higher bits, two levels are output. Based on brush distribution and encoding change rules, to read the level value corresponding to the higher-order binary code reflecting that position: when the brush on the lower-order track truly outputs "1", the true output on the higher-order track must be read from the lagging brush; if the brush on the lower-order track truly outputs "0", the true output on the higher-order track must be read from the leading brush. Since there is only one brush on the least significant bit track, its output represents the true position. This method is the V scanning method.

TR-Electronic encoder applications

The primary function refers to a program or device capable of compressing or decompressing digital video. It is a process of compression and potentially changing video content format, converting analog sources to digital sources. Both audio and video require customizable compression methods. In terms of compression, the goal is to reduce occupied space. Any digital video requires transmission via video encoder signals to better provide technical implementation for live video streaming. High-definition digital video codecs are video compression standards implemented through applications.

TR-Electronic encoder signal output

Signal outputs include sine wave (current or voltage), square wave (TTL, HTL), open-collector (PNP, NPN), and push-pull types. Among these, TTL is long-line differential drive (symmetrical A, A-; B, B-; Z, Z-). HTL is also known as push-pull output. The interface of the signal receiving equipment for the encoder should match the encoder. Signal connection—encoder pulse signals are generally connected to counters, PLC, and computers. Modules connecting PLC and computers are divided into low-speed and high-speed modules, with varying switching frequencies. For single-phase connection, it is used for unidirectional counting and unidirectional speed measurement. A.B two-phase connection is used for forward/reverse counting, direction determination, and speed measurement. A, B, Z three-phase connection is used for position measurement with reference mark correction. Connection of A, A-, B, B-, Z, Z- involves symmetrical negative signals, resulting in an electromagnetic field contribution to the cable of 0, minimizing attenuation and providing optimal interference resistance, allowing for longer transmission distances. For TTL encoders with symmetrical negative signal output, the signal transmission distance can reach 150 meters. For HTL encoders with symmetrical negative signal output, the signal transmission distance can reach 300 meters.
