Rotary encoder slit plate
Boasting a wealth of recruitment achievements, we are actively involved in the automation and labor-saving of production factories, and even in the aerospace field, supporting precision control worldwide.
We provide optical, resin-made slit plates used in encoders, motors, and robots. Products from the largest manufacturer of slit plates in China.
Using Japanese-made glass, with a diameter of Φ5 to Φ100 mm, thickness up to 6 mm, and resolution up to 100,000, we have an annual production volume of over 5 million units and a proven track record in Japan. Development sample delivery time is one month, and mass production delivery time is one to two months. With industry-leading automation equipment and manufacturing methods, we can maintain high quality.
Operational track record with domestic and international encoder sensor manufacturers! Reflective slit plates utilizing microfabrication technology and our unique Ni electroforming technology.
We propose high-quality reflective slit plates for the motor industry, which is moving towards miniaturization. Achieving a "DUTY ratio" of 50%:50%±2% that was considered impossible with etching, thanks to our Ni electroforming technology. We also support linear scales. We have numerous adoption records with encoder sensor manufacturers both domestically and internationally, particularly with reflective sensors. Our metal reflective slit plates are widely used in industrial equipment, consumer electronics, and automotive products. We also have a system in place to conduct operational checks in combination with encoder sensors before shipment. 【Specifications】 ■ Reflective area: over 60% ■ Non-reflective area: under 5% ■ Slit width accuracy: ±0.004um or less ■ Minimum slit width: 0.02mm ■ Minimum product size: φ2.0mm ■ Hardness (Hv): over 450Hv *For more details, please download the PDF or feel free to contact us.
Compatible with reflective absolute encoder ICs! A product realized through our unique Ni electroforming technology combined with fine photolithography technology.
We propose high-quality reflective slit plates that are optimal for reflective absolute encoders, which are being commercialized by various encoder IC manufacturers. This has been achieved through a combination of Ni electroforming technology and fine photolithography technology, which can accommodate the reflective/non-reflective random tracks for absolute encoders that are difficult to realize with etching alone. We also support absolute linear scales. Our products are already widely adopted in mass production for industrial equipment applications and automotive products. Additionally, we have a system in place to conduct operational checks in combination with encoder sensors before shipment. 【Specifications】 ■ Reflective area: 60% or more ■ Non-reflective area: 5% or less ■ Slit width accuracy: ±0.004um or less ■ Minimum slit width: 0.02mm ■ Minimum product size: φ2.0mm ■ Hardness (Hv): 450Hv or more *Please feel free to contact us.
