Advantages: The biggest advantage of absolute and incremental encoders are that they are inherently digital which means,, They can interface easily to modern control systems. An encoder sends digital quality signals back to the computer. There. Is no need for an engineer to get involved in the wiring and integration of signal electronics, In fact.Many engineers are unfamiliar with resolver Electronics - it is much easier to buy an encoder with a digital signal that. Is ready to go.
Disadvantages: The biggest limitations of encoders are that they can be fairly complex and contain some. Delicate parts. This makes them less tolerant of mechanical abuse and restricts their allowable temperature.One would be hard pressed to find an optical encoder that will survive beyond 120 º C. Optical encoders can be harmed by. Contamination - their fine-pitch scales LEDs and, photodetectors can be put out of action by oil dirt or dust. Probably,,, The biggest drawback to optical encoders are its reputation for mechanical fragility.The heart of most optical encoders is a thin glass disk that can be broken by excessive shock or misaligned by shock or. Severe vibration. Encoders traditionally have been complex electronic devices that contain integrated circuits as well as. LEDs, and photodetectors and a severe electrical disturbance could damage them.
