Introduction

AMN33112 is an optical motion sensor from Dynapar Corporation, a leading global manufacturer in the motion sensing industry. This sensor is a non-contact rotary motion sensor, designed to deliver precise positioning and speed measurements. The sensor is used in a variety of applications, ranging from robotic motion control to wind turbine blade pitch adjustments and automotive engine speed sensing.

Applications

AMN33112 can be used in applications where precise position or velocity measurements are required. This includes robotic motion control, automotive engine speed sensing and wind turbine blade pitch adjustments. Other possible applications include machine tool position sensing, scanning systems and industrial automation.

Working Principle

The basic working principle of the AMN33112 is based on optical sensing. The main component of the sensor is an encoder disk which has a series of concentric tracks of alternating dark and light bands. This encoder disk is placed between two active surfaces of the sensor; one consisting of a light source and a receiver, and the other consisting of a focusing lens. When the encoder disk rotates between the two active surfaces, the alternating bands of dark and light cause the light source and receiver to be activated, resulting in an electrical signal being generated. This signal is then sent to a processor which can calculate the position and speed of the encoder disk based on this signal.

Advantages of Using the AMN33112

The main advantage of the AMN33112 is its high accuracy and resolution. The encoder disk has a resolution of up to 60,000 pulses per turn, which means that precise position and speed measurements can be achieved. The sensor is also capable of delivering a constant output signal even in cases of mechanical shock or vibration, thanks to its “zero disturbance” feature.

Conclusion

The AMN33112 is an optical motion sensor from Dynapar Corporation. It is a non-contact rotary motion sensor, designed to deliver precise positional and speed measurements. The sensor is capable of producing up to 60,000 pulses per turn with its high accuracy and resolution, making it ideal for many applications, including robotic motion control, automotive engine speed sensing, wind turbine blade pitch adjustments and machine tool position sensing. Thanks to its “zero disturbance” feature, the sensor is capable of delivering a constant output signal even in cases of shock or vibration.
