Overview

WTB/WTA Wanhao optical ruler has a stroke of 50-3200mm and can be equipped with WE6800 digital display. Adopting a double-layer shielded wire with integrated injection molding and metal soft shell protection, it is waterproof, stable and reliable, especially suitable for long-distance transmission, and has strong signal anti-interference ability.

Product Details

WTB/WTA Wanhao Optical RulerAdvantages:
1. A single large-area light source composed of self-designed optical lenses has better parallelism and uniformity of light intensity than general LED light sources, thereby ensuring the stability of high-resolution states;
2. A single large-area light source overcomes the problem of aging and asynchronous use of traditional four pair LED light sources, significantly improving signal reliability after one year and reducing maintenance costs in the later stage;
3. The receiving module adopts carefully selected 6 large-area photodiodes packaged together, ensuring the reliability of electrical parameters, ensuring high-quality signal output, improving anti pollution ability, positioning accuracy, and response speed;
4. Adopting a double-layer shielded wire with integrated injection molding and metal soft shell protection, waterproof, stable and reliable, especially suitable for long-distance transmission, with strong signal anti-interference ability
5. Adopting independently developed sine wave signal subdivision chip, pure hardware processing, fast conversion speed, incremental A/B orthogonal signal output up to 2.5MHz;
6. Each grating ruler undergoes strict inspection and testing, and can provide accuracy testing reports to ensure product quality and quality traceability;
7. The sliding adopts high-quality imported five bearings, which can ensure long-term work repeatability and positioning;
8. The ruler body is made of aluminum alloy profiles that have been anodized, and the ruler head is made of alloy die-casting plated with hard chromium, which is corrosion-resistant and can work for a long time in harsh environmental conditions
