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
