How Heidenhain Encoders Have Benefited the Electronics Industry
When it comes to electronics, the faster and more precise, the better the product is. End users are looking for these results. This means the people who make the components need to be able to satisfy these demands with the right solutions. Miniaturization and lower costs are also important factors. But still, there is no place for sacrificing quality. This is where an optical linear encoder and other types come into play. There are many advantages of having these devices in your electronics operations.
The Makeup and Function of Encoders
Today, most encoders have an incremental or absolute type of measuring positions. Incremental measuring allows for counting. Each of these needs sinusoidal scanning signals to be of high resolution. This requires that the signals are interpolated. An exposed linear encoder, for example, can mitigate problems with poor scanning. Position errors can show up within one signal period of the encoder’s output signals. Ideally, quality encoders will have 1 percent to 2 percent of the signal period.
Use of an Optical Linear Encoder for Direct Drives
When it comes to direct drives in electronics, high-position signals with minimal interpolation errors are vital. The linear encoder needs to accomplish this. It is best that the sealed linear encoder or other type uses photoelectric scanning. The reason is that these devices can scan fine graduations. When an encoder has optical scanning, it can take advantage of direct drives and their possibilities.
Getting the Most out of Scanning Methods
To get a low interpolation error, there are a few factors. First, you need to consider the scanning method. Also, having high-quality grating will help achieve the optimal results. A single-field scanner is a good tool. Its output signals come from a single, large scanning field. An exposed linear encoder can help accomplish the following in this process:
- High traversing speed
- Low heat generation of the motor
- Low signal noise
- Low interpolation error
Low Contamination Sensitivity
In the electronics industry and those businesses that use semiconductors, compact designs are crucial. Such operations also need a high degree of acceleration. Exposed measuring systems fit well in these environments. They must work without friction and can be small. This is because the devices work without housing.
There is also reliable protection from contamination because of the special scanning methods. An exposed linear encoder works with single-field scanning. The encoders use only one scanning field to produce the scanning signals. The scanning field will also cut down on the sensitivity to contamination.
An Important Element for Linear Motors
If you work in electronics and with semiconductors, you should be familiar with encoders. An exposed linear encoder and other varieties can produce a wide range of benefits and help you achieve your goals. Call an expert at MDS Laser today to understand more about the role of encoders.
