2217901-2

2217901-2 is a type of rigid-flexible composite magnetic encoder. It is applicable to precision measuring and industrial automation technology. It is used in strict industrial environments, including gas, coal, petroleum, chemicals, and metallurgy.

The 2317901-2 supports connecting cables between 10cm to 5m in length, and works reliably in high temperature zones of -20℃ to +100℃. It uses an inductive magnetic segmented rotor to provide an absolute output of the measuring direction and displacement. The device provides a wide range of applications, including motion control and positioning, speed measuring, and rotary shaft angle.

The 2217901-2 consists of three main parts: a sensor, a rotor and a connecting cable. The sensor of the 2217901-2 consists of a rod and a core. The core contains several coils wound in a ferrite material, while the rod is a thin metal sheet with two magnets and a support rod. The rotor is a thin sheet containing the magnetic segmented rings, which interact with the coils of the sensor. Finally, the connecting cable connects the sensor and the rotor.

The 2217901-2 works on the principle of magnetic rotation. The rotor with the magnetic segmented rings rotates according to the increment angle per revolution. This rotation induces a current in the coils of the sensor, which encodes the rotary movement. The encoded output signal is a pulse train, indicating the absolute position of the rotor. The pulse train is sent through the connecting cable and is received by the microcontroller. The microcontroller then translates the signal into an absolute angle or position value.

The 2217901-2 is mainly used in measuring systems which require high accuracy and wide dynamic range. It has a high resolution of 12/14 bits and a sensing distance of up to 50mm. Its robust construction makes it suitable for harsh industrial environments. The device has an operating temperature range from -20℃ to +100℃, and it can also operate in high humidity or high dust concentration environment. 2217901-2 can be used in a wide variety of measuring applications, such as robotic arms, industrial machinery, conveyor systems, positioning and alignment systems, etc.

In conclusion, the 2217901-2 is a versatile, reliable and robust magnetic encoder which uses magnetic rotation principles to measure and encode absolute position or shaft angle. The device is suitable for the most demanding industrial applications, due to its wide operating temperature range and high resolutions.
