24V Wanhao grating ruler PLC electronic ruler

The power supply voltage of the 24V Wanhao grating ruler PLC electronic ruler is 24V, with a resolution of 1um or 5um and a measurement stroke of 50mm-3200mm. It has the advantages of easy installation, maintenance, and simple upkeep. According to customer requirements, the optional models include WTB5 series, WTB1 series, WTA5 series, WTA1 series, etc., with accurate measurement accuracy and long service life.

Application of Wanhao grating ruler:

The grating ruler produced by Wanhao is suitable for milling machines, machining centers, boring machines, wire cutting machines, spark machines, lathes, grinders, sawing machines, bending machinery, and testing equipment instruments. The grating ruler has good anti vibration performance and fast motion speed, which not only meets the requirements of conventional mechanical performance, but also meets the requirements of linear motor driving speed.

24V Wanhao grating ruler PLC electronic rulerAdvantages:

When measuring the position of the linear axis with a grating ruler, there are no additional mechanical transmission components. The control loop controlled by the linear grating ruler includes All feed mechanisms, with a linear grating ruler installed on the skateboard, can detect mechanical transmission errors and provide corrections in the control system circuit;

The linear grating ruler adopts a closed structure, with an aluminum shell protecting the grating, scanning unit, and track from dust and chips, and an elastic sealing strip protecting the sealing of the shell.

24V Wanhao grating ruler PLC electronic rulerMeasurement principle:

The grating ruler adopts incremental measurement method, and the grating of incremental measurement method is a periodic grating engraved line. Location information is obtained by calculating the incremental number (measured step distance) starting from a certain point. Due to the need to determine the position value using an absolute reference point, a track with a reference point is also engraved on the grating ruler. The absolute position of the grating ruler determined by the reference point is engraved with precision to one measurement step. Therefore, it is necessary to establish an absolute reference point or set it as the origin through a reference point. Grating ruler every50Millimeters have a reference point, and customers also engrave the position of the reference point customized according to the characteristics of their own equipment.

Wanhao grating rulerspecialPoint:
1.A single large-area light source composed of independently designed optical lenses, which is superior to conventional onesLEDThe light source has better parallelism and uniformity of light intensity, ensuring the stability of high-resolution state;
2.A single large-area light source overcomes the traditional use of four pairs of tubesLEDThe problem of asynchronous aging of light sources significantly improves the reliability of signals after one year, reducing maintenance costs in the later stage;
3.The receiving module is carefully selected6Only the large-area photodiodes are packaged as one unit, ensuring the consistency 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, incrementalA/BOrthogonal signal output up to2.5MHZ；
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 the repeatability and positioning of long-term work;
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
