アサ電子工業 List of Products and Services

The "magnetic proximity sensor" is a sensor that operates ON and OFF based on changes in the strength of the magnetic field. With a fast response time (under 5μsec), it can also be used for speedometers and tachometers. Compared to general proximity sensors, it is highly sensitive (large detection distance) and compact. It enables high-precision position detection (repeatability of 0.001mm) and can be useful for quickly detecting high-speed movements, helping to solve your concerns. 【Features】 ■ The operating principle is based on Hall IC, so it has a polar characteristic with S-pole detection as standard. ■ The double sensor can detect both the servo origin and overruns with a single unit. ■ It is less susceptible to radio noise interference. *For more details, please refer to the PDF document or feel free to contact us.

At Asa Electronics Industry, we handle the "High-Precision Air Cylinder Sensor." The body length is compact, ranging from 14.5mm to 24.5mm. While conventional sensors struggled to detect below 5mm, our product can detect down to 0.1mm. Additionally, while conventional sensors had a repeatability accuracy of about 10μm, our sensors achieve a repeatability accuracy of 1μm. 【Features】 ■ High precision ■ Capable of close mounting between cylinders ■ Compact ■ Resistant to high-temperature environments *For more details, please refer to the external link page or feel free to contact us.

The "Ball Coupling" is a rotational transmission element that combines the functions of a universal joint and a spline. It consists of three elements: an inner hub, an outer hub, and a ball, and has obtained a patent for its functional structure. Since there are no size limitations, the possibilities range from micro-sized to large couplings. It is possible to design couplings that meet the specifications required for actual use, including angular displacement and elongation (spline) amounts. 【Features】 ■ Particularly high breakage torque allows for miniaturization of devices ■ Can accommodate underwater, in oil, high temperatures, low temperatures, vacuum, etc. ■ Expected developments from micro robots to automatic machines, packaging machines, and large industrial machinery ■ Achieves zero backlash with a ball press-fit type ■ High-speed and high-rigidity servo compatibility can also be considered ■ The size and number of incorporated balls can be designed according to the application (record: up to 12 balls implemented) *For more details, please refer to the external link page or feel free to contact us.

The "QJ/QJU" is a cushion-type coupling that absorbs eccentricity, angular misalignment, and rotational vibration by deforming a cylindrical cushion surrounded by hub projections. The six cushions are completely independent, allowing each to effectively deform and easily accommodate misalignment and rotational vibrations. There are four types of cushion materials, and the differences in hardness manifest as variations in torsional and eccentric characteristics. 【Features】 ■ Zero backlash ■ Vibration and noise absorption ■ Cushions have a pipe shape, providing high flexibility and long lifespan ■ The material of the cushions allows for selection of high or low torsional rigidity ■ The hub material is aluminum die-cast, resulting in a small moment of inertia *For more details, please refer to the external link page or feel free to contact us.

At Asa Electronic Industry Co., Ltd., we handle the plastic coupling 'UJ/GJ'. "UJ" is suitable for light load transmission. It excels in bending fatigue resistance compared to metal, achieving light and smooth rotational transmission. "GJ" has a longer slit section compared to UJ, improving the allowable misalignment amount during standalone use. Both are widely used in rotational transmission parts where electrical insulation is required. 【Features (UJ)】 ■ Miniature size utilizing the fatigue resistance of engineering plastics ■ Superior bending fatigue resistance compared to metal materials like aluminum alloy, achieving light and smooth rotational transmission ■ Suitable for light load transmission in rotary switches, encoders, small motors, etc. ■ Widely adopted in rotational transmission parts requiring electrical insulation *For more details, please refer to the external link page or feel free to contact us.

This is a shaft coupling that absorbs eccentricity and angular misalignment through the elasticity of the cushion. The independent cushion evenly distributes the load and has a vibration and noise reduction effect for pulsating rotational transmission, such as in pumps. 【Features】 ● Soft cushion type coupling ● Versatile type usable in a wide range of rotating mechanisms ● Compatible with mechanisms that have eccentricity and angular misalignment ● Usable in rotating mechanisms that involve vibration ● Cushions are available in two types: soft (S) and hard (H), and are easy to attach and detach *For more details, please contact us or download the catalog.
