Introduction

SVK3A103AEA01B00 is a kind of position sensor, which belongs to angle, linear position measuring type. This kind of sensor measures position of object by rotating/angular motion or linear motion. The angle is calculated by outputted positive/negative electrical pulse, while the linear motion can be calculated by double pulse output method. The output signal type of SVK3A103AEA01B00 is transistor-transistor logic (TTL).

Application Field

SVK3A103AEA01B00 is widely used as command signal for control circuit and as feedback signal in servo-system. It is suitable for small tilting/linear motion detecting. The application fields include:

• Industrial automation
• Robotics
• Factory electro-mechanical automation
• Transmission and steering control devices
• CNC lathe
• Injection molding machine

Working Principle

SVK3A103AEA01B00 consists of a coded disc and a position logic circuit. When the coded disc is rotating, codes passes position logic circuit one by one and each time will output a rectangular pulse. For example, if SVK3A103AEA01B00 has 1024 codes, it sets a position bit every 3.96 degrees. Therefore, the outputted rectangular pulse will reach 1024 times per 360 degrees. According to changes of pulse width and the period of between two pulse, the angle can be calculated.

Apart from rotary motion, SVK3A103AEA01B00 can also be used for linear motion measuring. The method is similar as the above rotary motion measuring, except for the coded disc is moved linear instead of around an axle. Note: the number of codes for linear moving will affect the resolution and accuracy of the outputted linear measurement.

Conclusion

SVK3A103AEA01B00 is a position sensor, which belongs to angle, linear position measuring type. It is widely used in many industrial production places, such as industrial automation, robotics, factory electro-mechanical automation or CNC lathe. This position sensor uses coded disc to measure rotary/linear motions of objects, and outputted signal type is TTL. It is very useful for small angle/linear motion detecting.
