Encoders are used to translate the motion of an object into an electrical signal for the purpose of feedback in control systems. They are devices used to measure distance and rotation and are used in a variety of applications, ranging from machine tools and robotic applications to consumer electronics and medical devices. One particular type of encoder is the PEC11S-9215K-N0015. This article will provide an overview of the application field and working principle of the PEC11S-9215K-N0015.

Application Field

The PEC11S-9215K-N0015 is a rotary encoder that supports quadrature output. It is widely used in applications such as robotic positioning systems, servo and stepper motors, fuel injectors, and automotive HVAC applications, among others. The encoder is designed for use with either the Industry Standard Gray Code or Bi-directional counting method. It is a useful device when precision and repeatability are required. It is also a cost-effective solution for industrial motion sensing solutions, as it eliminates the need for expensive optical encoders.

Working Principle

The PEC11S-9215K-N0015 employs a rotary optical encoder technology to detect the position of a rotating shaft or capacitive element. A pair of phototransistors are located on a disc that is connected to the shaft or element. When the disc is rotated, one of the phototransistors will be exposed to light and the other will be blocked by the disc. When light is sensed by one phototransistor, the signal is sent to the other phototransistor, which then signals a logic circuit, allowing the system to detects the position of the disc. The output is typically quadrature-encoded, allowing for rotation direction and velocity measurement. The encoder is also capable of providing a pulse output, which can be used for tachometer applications.

In addition to the optical encoder, the PEC11S-9215K-N0015 also features a mechanical switch, which allows for the detection of a mechanical stop or limit. An 8-pin locking connector is used to output power or control signals from the encoder to help control the motion of the system. The PEC11S-9215K-N0015 is configured with three pins for the mechanical limit switch, two for the optical encoder, and one for power.

Conclusion

The PEC11S-9215K-N0015 is a versatile rotary encoder which is capable of providing both quadrature output and pulse output signals. It is designed for use with a variety of applications, including robotic positioning systems, fuel injectors, and automotive HVAC applications. The encoder is able to measure the rotation direction and velocity of a shaft or capacitive element and can be used to control the motion of a system. It also includes a mechanical limit switch, allowing for the detection of a mechanical stop or limit.
