Nemicon OSS-01-1C OSS series Single-turn absolute encoder

Nemicon OSS-01-1C is a single-turn absolute encoder in the OSS series. Here are some analyses of it:

Model meaning speculation: "OSS" represents the series name; "01" may represent the resolution of the encoder and other related parameters, such as the resolution may be 100P/R (pulse number/turn), because the similar models mentioned above "02" represents 200P/R, "03" represents 300P/R, etc.; "1" may be the version number of the product or other specific identification; "C" suffix usually indicates a specific output form, which may be complementary output or long-line drive output, etc., which needs to be determined by referring to the Nemicon official manual.

Working principle: Like the general single-turn absolute encoder, this model has an optical code disk inside, on which many optical channel lines are engraved, arranged in 2 lines, 4 lines, 8 lines, 16 lines, etc. At each position of the encoder, by reading the light and dark of each engraved line, a set of binary codes (Gray code) from 2 to the power of 0 to 2 to the power of n-1 can be obtained, where n is determined by the resolution of the encoder. In this way, each position of the encoder has a unique code, which is determined by the mechanical position of the photoelectric code disk and is not affected by power outages or interference.

Features:

High-precision position detection: As an absolute value encoder, it can accurately detect the absolute position of the rotating shaft within a single turn, provide accurate position feedback for the equipment, and is suitable for application scenarios with high requirements for position accuracy, such as precision machine tools, positioning control of automated production lines, etc.

Good data stability: With the absolute value encoding method, the position data read each time is uniquely determined, and there will be no cumulative error like the incremental encoder, and it is not easily affected by external factors such as electrical interference and vibration, and can work stably in complex industrial environments.

Power-off memory function: Even if the device is powered on again after power failure, it can immediately provide the current accurate position information without the need to re-return to zero or calibrate, reducing the startup time and maintenance cost of the equipment and improving the reliability and operation efficiency of the system.
