Teseek QHYCFW3S High Precision Motor Driven Color Filter Wheel Built-in Ultra-thin Hybrid Stepper Motor

Teseek QHYCFW3S High Precision Motor Driven Color Filter Wheel Built-in Ultra-thin Hybrid Stepper Motor

Description:
- QHYCFW3 adopts an ultra-thin hybrid stepper motor, which is built-in and not exposed, avoiding dust from entering the motor and improving reliability and motor life. Compared to most permanent magnet motors used in filter wheels, hybrid stepper motors also have the characteristics of small step angle, high resolution, and high precision; The motor adopts segmented drive, which avoids the spacing between gears and eliminates the maintenance issues caused by belt aging, while also having noise reduction function. CNC one-time processing, exquisite craftsmanship. By using a dedicated switch button, cameras can be effectively replaced with other brands of cameras, making it more convenient and efficient. The third-generation filter wheel can rotate clockwise or counterclockwise, which can quickly complete the rotation and is very convenient.
- The QHY third-generation filter wheel is divided into four specifications according to size, namely S, M, L, XL. And the small and medium sizes are each divided into two different thicknesses, namely the ultra-thin version (-US) and the standard version (-SR). It should be noted that the ultra-thin version only supports filters with a frame thickness not exceeding 5.5mm, so you need to choose between the ultra-thin or standard version based on the thickness of the filter frame.

Specification:
- Model: QHYCFW3S-SR/QHYCFW3S-US
- Back focus consumed: 20mm + 4mm for QHYCFW3S-SR/15.5mm+4mm for QHYCFW3S-US
- Filter supported: 7*1.25-inch mounted
- Usable height limit: 10mm for QHYCFW3S-SR/5.5mm for QHYCFW3S-US
- Weight: 446g for QHYCFW3S-SR/419g for QHYCFW3S-US

Back Focus Consumed:
- For the convenience of calculation, all the data displayed are the increase in the back focal length taken up by using the adapter, which is not necessarily equal to the thickness of the component itself. All the adapter data provided are based on the focal length increment.
- The Calculation of Filter Wheel’s back focus consumed includes two parts: The thickness of  the filter wheel body (like the 15.5mm of CFW3S-US), and the back focus consumed (like 4mm of CFW3S-US). Now new cams don’t need this adapter anymore, like QHY533M, QHY268M, QHY600M-PH SBFL, etc.

Package Included:
- 1 x Set of Filter Wheel

Note:
- QHYCFW3S-SR/QHYCFW3S-US is optional. Please leave a message about the model you want before payment.
- There’s no difference between S-SR and S-US expect their depth, but S-SR can be compatible with thicker 1.25” mounted filters.
