Product Advantages and Features
1.High Detection Precision
Adopts the principle of mirror-reflective photoelectric sensing with automatic alignment. Equipped with a PinPoint-LED light source that ensures stable light spot size—measuring Ø45mm at a distance of 1.5 meters (wavelength: 650nm)—enabling accurate detection.
2.Long Sensing Distance
Boasts a maximum switching distance of up to 5 meters and a sensing distance of 3 meters, meeting the requirements for detecting large-sized workpieces in woodworking machinery.
3.Easy Setup & Diagnosis
Supports IO-Link and is equipped with a single teach-in button for convenient parameter setting and debugging. It also features device contamination level monitoring and teach-in quality diagnosis functions, allowing timely detection of the sensor’s operating status.
4.Rich Output Functions
Pin 2 is configured with multiple interfaces, including an external input terminal, teach-in input terminal, transmitter shutdown input terminal, detection output terminal, logic output terminal, and device contamination alarm output terminal, satisfying diverse control and monitoring needs. The switching output is PNP, with switch type switchable between light-on/dark-on modes. The maximum output current (Imax.) is ≤100mA, the response time of Q ranges from 300µs to 450µs, and the switching frequency can reach 1000Hz.
5.Wide Adaptability
Operates within a wide supply voltage range of 10V DC to 30V DC (with residual ripple <5Vss) and has a current consumption of 20mA, ensuring stable performance under varying voltage conditions. With an protection rating of IP67/IP66, the sensor features an ABS plastic housing and PMMA optical components. It can operate in an ambient temperature range of -40°C to +60°C and be stored at -40°C to +75°C, delivering excellent dustproof, waterproof, and environmental adaptability.
6.Special Functions
Equipped with a polarizing filter, it has the special function of detecting transparent objects. By activating the continuous threshold adaptation function (presettable by time), it is suitable for transparent object detection (e.g., 50% closing: 2-5s teach-in). This model is compatible with the WLG4SC-3P2232A91.

Product Application Scope
With its unique performance, the Woodworking Machinery Sensor - Reflective Grating (Model: 4008611536) plays a crucial role in various woodworking and related equipment. The specific applications are as follows:
Sawmill Equipment: In the production process of sawmills, the sensor is involved in the integrated speed and length measurement system. After the wood is cut, it can accurately measure the dimensions of the cut wood for quality inspection. Once there is a tolerance deviation in the dimensions, the sensor will feed back information to adjust the sawing equipment in a timely manner, thereby ensuring the stability of wood processing quality and meeting production standards.
Product Description
Comparison Dimension | Reflective Grating 4008611536 | General Grating Displacement Sensor (Grating Ruler) |
Detection Principle | Photoelectric reflective type, based on autocollimation principle. Visible red light is directly reflected back to the sensor from the target without the need for an additional reflector. A pinpoint LED generates a small and clear light spot for accurate detection. | Based on the moiré fringe principle. Light is projected onto a carrier engraved with gratings to form moiré fringe images. When the grating ruler moves, the light intensity of the image changes periodically, and displacement is detected through photoelectric cells and electronic signal processing. |
Detection Range | Maximum sensing range: 0m...5m; Sensing range: 0m...3m. The light spot diameter is 45mm at 1.5m, suitable for high-precision detection of short and medium-range, short-distance targets. | Measurement range: 10mm to 30m, covering the stroke of most metal cutting machine tools. Common accuracy: ±0.008mm, ±0.01mm, ±0.015mm (20℃, 1000mm). It has a large detection range but is slightly less effective in detecting small short-distance targets. |
Application Focus | Detection of wood characteristics (such as knots, cracks) in woodworking machinery and workpiece position detection during processing. Suitable for complex tenoning of Homag woodworking machine tools, quality control and sorting in wood product production lines, etc. | Mainly used for displacement measurement and digital display of linear moving guide mechanisms in metal cutting machine tools, as well as position loop control of CNC machining centers. It is widely used in linear displacement measurement of woodworking machinery, but has weak ability in wood characteristic detection. |
Light Source & Light Spot Characteristics | Adopts pinpoint LED light source, with small and clear light spot (only 45mm in diameter at 1.5m), which has obvious advantages in detecting small and precise targets. | No specific emphasis on light spot characteristics; mainly detects displacement based on moiré fringes. |
Adaptability & Function Integration | Equipped with adaptability, which can automatically adjust detection parameters. Integrates multiple functions such as external input, teach-in input, transmitter off input, detection output, logic output, and device contamination alarm output. | Some have basic functions such as detection output, but have weak ability to adapt to environmental changes. |
In the production operation of woodworking machinery, sensors serve as the core detection components, and their performance directly affects production accuracy, efficiency, and stability. Woodworking machinery sensor reflection grating 4008611536 has become the preferred choice for many enterprises due to its unique advantage of adapting to woodworking scenes.
