Encoders:

DP11SVN15B15P is an encoder used for the motion control industry. It can measure rotary incremental and absolute displacement. It has many features such as long life (>20 million revolutions) and accuracy 0.50 mm.

The DP11SVN15B15P encoder has two types of signals, the A-phase and the B-phase, transmitted by a 17-bit shift-register and outputted in single ended TTL/CMOS format. The encoder consists of a rotor with two phase disks, 15 bars each and a stator with an excitation-coil, mounted with a spring loaded conical shaped sensing element. This sensing element senses the out-of-phase magnetic field, depending on the angle between the two disks. It also contains a LED which is used to give a reference pulse frequency (RFF).

The application fields of DP11SVN15B15P encoder mainly include positioning applications, robotic arms and CNC machine tools, as well as for controlling actuators, valves and pumps. DP11SVN15B15P is also used in medical equipment, communication systems, industrial automation and robotics. Furthermore, it is used for preloaded motor applications, where speed needs to be accurately measured and controlled, such as in manufacturing, conveyor systems, and servo systems. Lastly, it is used in harsh environment applications like marine and automotive applications.

The working principle of DP11SVN15B15P encoder is based on the use of a stator coil, an incremental or absolute rotor position sensor, and a reference frequency (RFF). The stator coil produces a fixed magnetic field, and when a rotor is placed in the stator coil, it creates a variable magnetic flux that can be sensed by the incremental or absolute rotor position sensor. The rotor position is detected by the direction of the magnetic flux and the RFF provides the necessary timing for the encoder to report a change in the rotor position.

The main component of the DP11SVN15B15P encoder is a bridge type transducer. This transducer measures the angular position of the rotor by detecting the variable magnetic flux, generated by the stator coil. This transducer has two magnetoresistive components, amplified and conditioned analog signals are then fed into a differential amplifiers, whose output is then fed through a conventional up/down counter. The output of the counter is then coupled to an LED emitter, which produces the RFF.

DP11SVN15B15P encoder is widely used in motion control industry. With its excellent features, such as long life and high accuracy, it is used in numerous applications, as discussed above. In addition, the working principle of this encoder is straight forward and reliable, making it an ideal solution for most motion control applications.
