German P+F encoder P+F model P+F price

P+F encoder is a new type of angle or displacement measurement device. Its principle is to use magnetoresistive elements to measure the angle or displacement value of changing magnetic materials. Changes in the angle or displacement of the magnetic material cause changes in resistance or voltage, which are processed by a microcontroller to output pulse signals or analog signals for measurement purposes. Concentric code tracks extend from the center of the magnetic encoder disk outward to the edge of the disk, with each layer having twice as many sectors as the inner layer. The first layer has only one transparent sector and one opaque sector; the second layer at the center has two transparent sectors and two opaque sectors; and the third code track has four transparent sectors and four opaque sectors. The built-in sensor head is compact, suitable for small installation spaces, and features a high protection rating design, making it suitable for harsh environments. In industrial applications, it avoids the sensitivity to environmental pollution common in optical encoders, increasing long-term system stability.

P+F encoder principle

An optical encoder is a sensor that uses the principle of grating diffraction to achieve displacement-to-digital conversion. Through photoelectric conversion, it converts the mechanical geometric displacement on the output shaft into digital pulse quantities. Common optical encoders consist of a code disk, a light-emitting element, and a photosensitive element. The grating is essentially a disk with regular transparent and opaque lines. The light flux received by the photosensitive element changes synchronously with the transparent lines. The waveform output from the photosensitive element is shaped into pulse signals, with one pulse output per revolution. Based on pulse changes, equipment displacement can be precisely measured and controlled. Incremental encoders directly use the photoelectric conversion principle to output three sets of square wave pulses: A, B, and Z phases. The phase difference between the A and B pulse groups is 90º, allowing easy determination of rotation direction, while the Z phase provides one pulse per revolution for reference point positioning. Its advantages include simple construction, a mechanical average life of tens of thousands of hours, strong anti-interference capability, high reliability, and suitability for long-distance transmission. Its disadvantage is the inability to output absolute position information of the shaft rotation.

P+F 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, HD-SDI signal sources). Common encoding methods include MPEG-2, MPEG-4, H.264, H.265, etc., encoding the signals into TS stream data for real-time transmission. 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 via RJ45. The IP data stream generally supports protocols such as TS/HLS/RTSP/FLV/RTMP/UDP/RTP/unicast/multicast.
