SE40 Grating system

- SE40 series gratings are compact gratings for high dynamic and high precision systems. The application of single-field scanning and low-latency subdivision processing make them have high dynamic performance. Used in applications that are demanding on performance and cost at the same time, in pursuit of performance and product cost, an effective balance has been achieved.

- The SE40 series readhead is adapted to the L4 series ultra-thin stainless steel scale with a 40m grating pitch. The expansion coefficient is exactly the same as that of the substrate, and its excellent corrosion resistance and scratch resistance make it suitable for harsh environments. The surface of the L4 scale is very Tough, so it doesn't need any protective coating to prevent the grid lines from being damaged. When the scale is contaminated, alcohol can be used to clean it, and non-polar organic solvents such as acetone and toluene can be used instead of alcohol, and the performance of the scale after cleaning will not be affected in any way.

Primary advantages

- Small and compact readhead
- Single field scanning, low subdivision error.
- The magnetic zero point can be set arbitrarily, which is flexible and convenient.
- Ultra-light 7g readhead, ultra-flexible 3.4mm diameter cable, small inertia, does not affect system performance.
- Automatic gain control to ensure effective signal strength and long-term reliability.
- The reading head has 2 indicator lights visible in two directions, which is convenient for observing the signal status.
- Read head with optical coating, high signal-to-noise ratio.
- The surface of the scale is hard without coating and has strong scratch resistance.
- Scale with a thickness of 0.1mm has the same expansion coefficient as the substrate.
- 40m small grid pitch, better running effect than magnetic grid, low noise and stable speed.
- Maximum speed 4.5m/s.
- 10m/m scale absolute accuracy

AM4·series grating system

High-precision small-volume series grating ruler and reading head



Primary advantages

- AM4 series grating system is a compact grating for high dynamic precision system, single-field scanning application and low-latency subdivision processing, so that it has excellent dynamic performance.

- The AM4 series grating system is adapted to the M4 series ultra-thin stainless steel scale with a 40m grating pitch. The expansion coefficient is exactly the same as that of the substrate, and no separate temperature compensation is required.

- Corrosion-resistant, wear-resistant scale, high-strength scale, can effectively prevent the damage of the scale, making it still applicable in places with harsh environments. The scale surface is uncoated and when contaminated, the scale can be cleaned with solvents.

RX2·series grating system
High precision optical zero reading head


Primary advantages

- RX2 series incremental grating system is equipped with advanced optical zero position sensor, which can provide higher repeat positioning accuracy, and the zero position detection of the reading head is not affected by the magnetic field and is more stable.
- The RX2 series grating system is equipped with a zero selection sensor, which can select the origin on the RXS scale through a zero selection magnet.
- RX2 series grating system is equipped with double limit sensors.
- RX2 series grating system adopts advanced zero-point single-field scanning technology, advanced automatic gain and automatic deviation correction technology, low electronic subdivision error, and strong anti-pollution performance.
- RX2 readhead is compatible with RXS linear scale and PI20 circular scale
