Encoders: PEC12-2130F-S0012 Application Field and Working Principle

Encoders are devices which measure motion or position changes by converting them into digital pulses which can later be interpreted into motor speed and direction. Encoders are instrumental for a variety of industrial applications, such as remote control, robotics, navigation systems, and more. The PEC12-2130F-S0012 is one such encoder, and today we will discuss its application field and working principle.

Application Field

The PEC12-2130F-S0012 is a specially designed 360° incremental encoder with a standard version of 1 pulse per revolution and maximum version of 12 pulses per revolution. Its IP67 protection rating makes it suitable for multiple environments, be it indoor, outdoor, or other suitable conditions. The device features five terminals, a total body size of 28.5mm, and a solid shaft type with the rated frequency up to 200kHz.

The broad application field for this encoder ranges from small, low-power applications which simply require precise speed and direction readings to complex industrial or commercial operations involving motion systems and multiple motors. They can be used to monitor and control both speed and position including electric motors, servo systems and inverters.

Working Principle

At its most basic level, an encoder is made up of a set of interlocking slotted wheels and a row of light-emitting diodes (LEDs). When the wheels rotate, the passing slots interrupt the light emitted from the LEDs and the encoder’s integrated circuits generate a "square-wave" output, which is interpreted as a digital count. The number of pulses per revolution of the encoder determines its resolution, with the PEC12-2130F-S0012 featuring up to 12 pulses per revolution.

The encoder’s count output is determined by the number of slotted holes times the rates of the rotation. Depending on the direction of rotation, digital sensors can be used to determine the forward and reverse rotation of the encoder. These directional signals are then sent to a PLC or HMI, where upon further analysis can be used to specify the direction and speed of the motor.

There are two different types of input signals into an encoder, incremental and absolute. Incremental encoders, such as the PEC12-2130F-S0012, measure the angular position of a shaft relative to some starting position, while absolute encoders measure positions relative to some fixed reference point. In comparison to the latter, incremental encoders are generally much cheaper and more suited for fast applications, while absolute encoders are slower but more reliable in the long run.

In conclusion, the PEC12-2130F-S0012 encoder is an excellent choice for use in a wide range of industrial and commercial applications. Its IP67 protection rating, broad range of terminal sizes and sturdy construction make it a reliable and durable device. The up to 12 pulses per revolution resolution also makes it an ideal choice for operations which require precise speed and direction readings.
