Abstract
The utility model relates to a photoelectric limit circular grating sensor. One ring or multiple rings of photic and shading alternate code channels for photoelectric limit is/are produced on a circular grating, and a luminescent tube and a photoelectric detector are correspondingly mounted on two sides of the code channels for photoelectric limit. The photoelectric detector is mounted according to different photic and shading angles and different angle positions for meeting the requirements of different limit angles.
Description
Technical field
The utility model relates to field of photoelectric technology, particularly a kind of be mainly used in measurement of angle or velocity survey the spacing circular raster sensor of photoelectricity arranged.
Background technology
Circular raster sensor is widely used at industrial circle, this The Application of Technology and the history in existing more than 50 year of development, and there is numerous products in industrially developed country such as America and Europe and Japan, and China like product occurred before 30 years.Can be respectively applied for as the measurement of angle in textile machine, precision machine tool, the exact instrument according to the difference of the measuring accuracy of circular raster sensor, response speed.
In the measurement and control of angle, usually need to use positive and negative limit signal, and present circular raster sensor can not provide positive and negative limit signal.
The utility model content
The utility model discloses the spacing circular raster sensor of a kind of photoelectricity, by on the circle grating, make a circle or multi-turn printing opacity alternate with shading be used for the spacing code channel of photoelectricity, and in the spacing code channel of photoelectricity both sides corresponding luminotron and the photodetector installed.And photodetector is installed by printing opacity and the different of shading angle and in different angle positions, satisfy the requirement of different spacing angles.
Wherein, the photoelectricity limit signal can also can be exported with serial mode with the angle position data of circular raster sensor by independently signal wire output.
The utility model has solved the problem that circular raster sensor can not provide positive and negative limit signal, for people's use provides convenience.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model side view.
Embodiment
Consult Fig. 1, Fig. 2, the spacing circular raster sensor of a kind of photoelectricity, on the basis of traditional circular raster sensor, by on circle grating 3, make a circle or multi-turn printing opacity alternate with shading be used for the spacing code channel of photoelectricity 1, and at the spacing code channel of photoelectricity 1 both sides correspondence installation luminotron 2 and photodetector 4, thereby provide positive and negative limit signal.
Wherein, the photoelectricity limit signal can also can be exported with serial mode with the angle position data of circular raster sensor by independently signal wire output.
Claims (2)
1. spacing circular raster sensor of photoelectricity, comprise the circular raster sensor body, it is characterized in that: on the round grating of circular raster sensor, set up a circle or multi-turn printing opacity alternate with shading be used for the spacing code channel of photoelectricity, and in the spacing code channel of photoelectricity both sides corresponding luminotron and the photodetector installed.
2. according to the spacing circular raster sensor of the described a kind of photoelectricity of claim 1, it is characterized in that: described photoelectricity limit signal adopts independently signal wire output or exports with serial mode with the angle position data of circular raster sensor.
