German Turck encoder Turck model Turck price

Turck encoders convert displacement into periodic electrical signals, which are then converted into counting pulses, with the number of pulses representing the magnitude of displacement. According to their 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 size of the displacement. An encoder is a device that converts angular 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. Contact types use brush output, where a brush contacting a conductive or insulating area indicates whether the code status is "1" or "0"; non-contact types use photosensitive or magnetosensitive elements as receiving sensors. When using photosensitive elements, transparent and opaque areas indicate whether the code status is "1" or "0".

Turck encoder installation and usage

Mechanical installation and use of absolute rotary encoders: 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, and the motor rotation falls within this range, the full range can be utilized to improve resolution. The disadvantage is gear backlash error during forward and reverse motion after passing through reduction gears, so it is generally used for unidirectional high-precision control positioning, such as roll gap control in steel rolling. Additionally, when the encoder is directly installed on the high-speed end, motor vibration must be minimal; otherwise, the encoder is easily damaged. 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. It is generally used for long-distance positioning measurements, such as in various lifting equipment and feed cart positioning. Auxiliary mechanical installation: Common methods include rack and pinion, chain and belt, friction wheels, and rope reeling mechanisms.

Turck encoder component differences

From single-turn absolute encoders to multi-turn absolute encoders. For an absolute rotary single-turn absolute encoder, unique codes are obtained by measuring the tracks on the optical code disk during rotation. When rotation exceeds 360 degrees, the code returns to the origin, which violates the principle of unique absolute encoding. Such encoding can only be used for measurements within a rotation range of 360 degrees and is called a single-turn absolute encoder. To measure rotation beyond 360 degrees, multi-turn absolute encoders are used. Encoder manufacturing employs clockwork gear mechanics. When the central code disk rotates, another set of code disks (or multiple sets of gears and code disks) is driven via gear transmission. Counting of turns is added to the single-turn encoding to expand the encoder's measurement range. This type of absolute encoder is called a multi-turn absolute encoder. It also determines encoding by mechanical position, ensuring each position code is unique and non-repeating without the need for memory. Another advantage of multi-turn encoders is that due to the large measurement range, there is often considerable margin. Thus, during installation, there is no need to struggle to find the zero point; any intermediate position can serve as the starting point, greatly simplifying installation and commissioning.

Turck encoder wiring methods

A rotary encoder is a photoelectric rotary measurement device that directly converts measured angular displacement into digital signals (high-speed pulse signals). Encoders are classified by signal principle into incremental encoders and absolute encoders. We commonly use incremental encoders, which can input output pulse signals directly to the PLC, utilizing the PLC's high-speed counter to count the pulse signals and obtain measurement results. Different models of rotary encoders have different output pulse phases. Some rotary encoders output three-phase pulses A, B, Z; some have only two phases A, B; and the simplest has only one phase A. The encoder has 5 lead wires, of which 3 are pulse output lines, 1 is the COM terminal line, and 1 is the power line (OC open-collector output type). The encoder's power supply can be an external power source or directly use the PLC's DC24V power supply. The power supply "-" terminal must be connected to the encoder's COM terminal, and "+" to the encoder's power terminal. The encoder's COM terminal connects to the PLC input COM terminal. The A, B, Z two-phase pulse output lines connect directly to the PLC input terminals. A and B are pulses with a 90 degree phase difference. The Z phase signal produces only one pulse per encoder revolution and is typically used as a zero reference. Pay attention to the PLC input response time during connection. The rotary encoder also has a shielded wire, which must be grounded during use to improve anti-interference performance.
