Encoders are ubiquitous in many industrial applications and are used for various purposes. PEC12R-2225F-N0024 is one such specialized encoder with applications in industrial automation. In this article, we will explore the application field and the working principle of the PEC12R-2225F-N0024 encoder.

Applications of PEC12R-2225F-N0024 are found in industrial automation where the device is used to provide interfacing between CNC machines for manufacturing control. It is designed mainly for rotary motion measurement with direct connection to stepper motor, feedback for precise positioning of dynamic systems. The encoder provides high reliability and cost effectiveness for these applications.

The PEC12R-2225F-N0024 encoder has a rotary design with rotating coded disc in it and an optical sensing device for detecting the rotations. The outer disc has a series of thin grooves running across its circumference. The grooves are arranged in concentric circles with little angled marks or ‘teeth’ that run across them.

When the encoder is rotated, the angled marks disrupt the optical beam casted by the opto-interreneur which is housed in the encoder. This opto-interreneur is made up of an infrared LED and a phototransistor. As the encoder is rotated, the LED shines the infrared beam to the phototransistor which detects any disruption in the beam created by the angled marks on the code disc.

The output signal of the encoded is digital with an optical quadrature output which operates upon the principle of two-phase-incremental encoding. The quadrature signals are used to provide the speed and direction of the motor and generate two digital synchronous square wave signals, with a 90° phase difference between them. The digital output can be used by a controller to control the motor speeds for precise motion measurements.

The PEC12R-2225F-N0024 provides up to 250 pulses per revolution and its position is 0.7° ± 10% between the two complementary output phases. The detector has a rise and fall delay time of 10 ns and frequency of up to 5 khz. Additionally, the encoder can also provide shock and vibration resistance against industrial vibration and shocks of up to 500 G. All these features contribute to make the encoder a reliable and accurate solution for industrial automation applications.

To conclude, the PEC12R-2225F-N0024 encoder is a specialized encoder with applications in industrial automation. The encoder has a rotary design with rotating coded disc and an opto-interreneur for sensing rotations. The output of the encoded is digital with an optical quadrature output which is used to generate two digital synchronous square wave signals with a 90° phase difference between those signals. The encoder also provides shock and vibration resistance and precise motion measurements for industrial automation applications.
