NSE12DV1225 Encoders

NSE12DV1225 encoders are high precision rotary encoders used for various industrial applications such as robotics, precision motion control, and production automation. The encoders feature dual 10 bit encoder resolution with integrated TTL output and solid-state technology, allowing for a high accuracy level and reliable operation.

Application Field and Working Principle

NSE12DV1225 encoders are typically used in robotics, precision motion control, and production automation where accuracy and reliability are of high priority. The two output phases provide a 10-bit resolution per revolution, for a total resolution of 2000 counts per revolution. This high resolution output is achieved through a two channel optical encoder, contained in the single unit. The encoder also offers TTL logic output, providing a high speed output signal.

The main component of an NSE12DV1225 encoder is a two channel optical encoder, composed of two slotted disc-shaped elements. The first disc, referred to as the codewheel, contains several equally spaced slots or ‘windows’ around its circumference and is positioned in front of an LED or infrared light source. The second disc, the codebar, also contains several slots placed around its circumference. The combination of LED or infrared light, the codewheel and the codebar results in a system that can detect and process changes in the relative positions of the two discs.

As the codewheel rotates, it passes through a light beam created by either the LED or infrared source. As the codewheel passes through the light beam, the codebar will allow light to pass through its slots if they align with the light beam. In this way, the codebar fades in and out of the light beam, depending on the relative position of the codewheel. Each time the codebar fades into the light beam, the encoder will output a high, or ‘1’ signal and each time the codebar fades out of the light beam, the encoder will output a low, or ‘0’ signal. By counting the number of times the codebar transitions from high to low and vice versa, the encoder is able to detect the surface rotation and the position of the coded wheel. As each slot of the codewheel passes through the light beam, the encoder is able to record the position with an accuracy of up to 10 bits per revolution.

Thus, the NSE12DV1225 encoder is a high precision rotary encoder that provides an accurate output signal, ideal for robot navigation, precision motion control, and production automation. It is also an ideal choice for applications where absolute position feedback is required, as the NSE12DV1225 offers 2000 counts per revolution and provides a TTL output for a high speed connection.
