Roundss encoder Incremental encoder！
Changchun Rongde Optics Co.,Ltd. Release time：2016/8/17 Browse：665Incremental encoder works
It consists of a center axis of the optical encoder, which has a ring through the dark of the engraved lines, optoelectronic transmitting and receiving device to read, get a sine wave signals into four groups A, B, C, D, each sine wave phase difference of 90 degrees (with respect to a cycle of 360 degrees), the C, D inverted signal, superimposed on a, B on the two-phase, can enhance stabilization signal; output per rotation other Z-phase pulse to represent a zero reference bit.
Since the A, B two-phase difference of 90 degrees, the first phase A or B by comparing the first phase, in order to determine the encoder forward and reverse, the zero pulse can be obtained encoder zero reference position.
Encoder code disc material glass, metal, plastic, glass code discs are deposited thin engraved lines on the glass, good thermal stability, high accuracy, metal code disc directly through the barrier and engraved lines, non-friable, However, since the metal has a certain thickness, there are restrictions precision, thermal stability than, an order of magnitude difference in glass, plastic code disc is the economy, and its low cost, but the accuracy, thermal stability and life are worse some.
Resolution - 360 degrees per encoder rotation through or how much dark groove called the resolution, also known as analytic indexing, or direct say how much wire, usually 5 degrees per rpm to 10,000 lines.
Roundss production and sales of various types of incremental encoders, absolute encoders, linear encoders, and an encoder associated couplings, switches, MPG and so on. Welcome to the new and old customers to purchase consulting, roundss will try our best to do your technical support.
