The "HC" suffix in the Nemicon OSS-03-2HC encoder of the OSS series likely denotes a specific output type or electrical characteristic.
The OSS series are incremental encoders. The OSS - 03 - 2HC, in particular, has the following general features:
Dimensions: It has an outer dimension of Ф30×30 mm and a shaft diameter of Ф4 mm with a D - shaped notch.
Pulse count: The pulse count can range from 60 p/r to 500 p/r.
Voltage: It can operate with a voltage of 5 - 12V or 12 - 24V.
Output signals: It provides output signals of phase A and phase B, and can also have an origin Z output.
Output form: It features an open - collector output.
Maximum response frequency: The maximum response frequency is 150 kHz.
Maximum rotational speed: The maximum rotational speed is 6000 r/min.
Protection level: The protection level is IP50.
Operating temperature: The operating temperature range is - 10℃ to + 70℃.
The "HC" might indicate a high - voltage output version or a specific configuration related to the output circuitry, such as a different transistor type or drive capability compared to other variants without the "HC" suffix. However, the exact meaning would typically be specified in the product documentation provided by Nemicon. If you need detailed and accurate information, it is recommended to refer to the official technical manual or contact Nemicon's customer service.
