The difference between the magnetoelectric encoder and photoelectric encoder

What are the strengths and weaknesses of the magnetoelectric encoder and the photoelectric encoder? They mainly lies in the difference between principle and requirement and so on. The principle of the magnetoelectric encoder magnetoelectric encoder is developed in recent years a new type of speed, position detection digital sensors. Magnetoelectric encoder in strong magnetic material on the surface of record interval of magnetization such as scale, scale relatively placed beside the magnetoresistance effect components or hall element, which can detect the change of the magnetic flux, again through the signal conversion card processing into a standard electrical signal output. Magnetoelectric encoder advantages: 1. High speed, fast response speed 2. Dust, oil. 3. High resistance to vibration grade 4. Debug is convenient, installation simple 5. Line driver output type, strong anti-interference ability, suitable for long term output. What are the advantages and disadvantages of photoelectric encoder? Photoelectric encoder of advantages: small volume, precision, resolution itself can be very high, no contact wear; Same breed is detectable Angle displacement, and can help in mechanical conversion device to detect linear displacement; Many photoelectric absolute encoder can detect a considerable range of linear displacement ( If more than 25 circle) 。 Install optional, interface form rich, the price is reasonable. Mature technology, has been widely used at home and abroad years ago. Photoelectric encoder faults: precision but for outdoor and used under the bad environment put forward higher protection requirements; Relies on measuring linear displacement mechanism transformation, to avoid the error caused by mechanical clearance; Slip detection objects orbiting difficult to overcome. Shanghai is a professional manufacturer of magnetoelectric encoder, electronic products production of magnetoelectric encoder performance not easily affected by dust and condensation; Its simple and compact structure, non-contact, long life, high and low temperature resistance, resistance to vibration, fast response speed. Cost is low. Products used in robot, automatic production lines, automatic assembly machine, elevator, textile machinery, sewing machinery, packaging and printing machinery, CNC machine tools, mapper and Angle measuring instrument, etc. This encoder is also can be in PLC application as the high speed signal input element, make PLC more quickly and accurately implement the closed-loop control. Looking for magnetoelectric encoder is electronic.
