In the field of long-distance precision inspection in industrial automation, the HC26-195 series laser displacement sensor independently developed by Wuxi Hongchuan Technology has become an ideal choice to replace the OPTEX CD33 series and the SICK OD2 series from Germany, with its precise measurement ability at a reference distance of 195mm, super strong environmental adaptability, and flexible compatibility. This sensor is designed specifically for medium to long-distance measurement scenarios, integrating the advantages of large-scale detection, stable performance, and localized adaptation, providing cost-effective solutions far beyond imported products for industries such as warehousing and logistics, large-scale equipment manufacturing, and coil processing.A domestically produced laser displacement sensor with a large range of 200mm and an error of 0.2mm
The HC26-195 series is equipped with a 655nm red semiconductor laser (Class 2, 1mw), achieving an ultra wide detection range of 99.98mm at a reference distance of 195mm, covering the core requirements of medium to long distance measurement. Its static repeatability accuracy reaches 50um, linearity is controlled at ± 0.1% F.S., temperature drift is only 0.05% F.S./° C, and it maintains data stability in a wide temperature environment of -10 ° C~+50 ° C. This performance is particularly critical in long-distance measurement scenarios, demonstrating better environmental anti-interference ability compared to the Autese CD33 series (mostly suitable for short distances) and the Sike OD2 series (with significant accuracy attenuation over long distances).
Spot design optimized for long-distance scenarios: the proximal spot size is 230 × 600um, and the distal spot size is extended to 700 × 3300um. The 700um beam diameter can maintain focusing stability at long distances, which can meet the flatness detection of large workpieces (such as machine tool guides and large molds), as well as the contour measurement of rough surfaces (such as castings and composite materials), solving the pain points of spot divergence and accuracy decline in imported series at long distances.A domestically produced laser displacement sensor with a large range of 200mm and an error of 0.2mm.
HC26-195 achieves a detection range of 99.98mm with a reference distance of 195mm, far exceeding the coverage capability of the Autese CD33 series (mostly designed for short distances, with a reference distance usually ≤ 100mm) and the Sike OD2 series (with a detection range of up to 80mm for long-distance models). This advantage allows it to be directly applied to scenarios where imported products are difficult to adapt to, such as detecting the flatness of large turntables, monitoring the remaining amount of large-size coils (such as diaphragm coils and metal strips), and positioning large workpieces, without the need to build additional multi-sensor splicing systems, greatly reducing equipment deployment costs.
The protection level reaches IP67 (IEC standard), which can operate stably in humid workshops and dusty storage environments, surpassing the IP65 protection level of some imported models; The design of shielded high flexibility cables supports direct assembly on robot arms and can withstand vibrations of 10~55Hz with double amplitudes of 1.5mm (tested in XYZ directions for 2 hours), solving the problem of cable breakage in dynamic long-distance detection of the Sik OD2 series. In addition, glass lenses are used for the light outlet and receiving area. Compared with the acrylic lenses of the Autesi CD33 series, the temperature resistance is increased by 40% and the corrosion resistance is enhanced by 60%. The service life of imported products is extended to more than twice that in high-temperature workshops (such as foundries) or environments with chemical vapors.
Built in automatic brightness adjustment function, which can optimize laser intensity in real time based on the reflective characteristics of the tested surface (such as the high gloss area of large metal parts and the matte surface of composite materials), solving the problem of signal instability caused by surface reflection differences in imported series for long-distance measurement. External input supports functions such as laser shutdown, remote teaching, sample and hold (sampling time ≤ 3ms), single pulse triggering, etc. The response time can be flexibly switched between 333us and 2000us, adapting to the detection rhythm of different production lines. This flexibility far exceeds the fixed mode of the Autesi CD33 series and is also better than the response delay problem of the Xike OD2 series over long distances.
Supports RS485 communication (compatible with Modbus RTU protocol), analog output can independently select 0~10V voltage (output impedance 100 Ω) or 4~20mA current (load resistance ≤ 300 Ω), and is also compatible with EtherCAT module, which can directly interface with domestic PLCs, industrial robots or data acquisition systems. In contrast, the Xike OD2 series requires a dedicated protocol conversion module to adapt to domestic devices, while the communication interface compatibility of the Otes CD33 series is limited. The multi interface design of the HC26-195 reduces system integration costs by more than 50%, significantly shortening the deployment cycle of replacing imports.
HC26-195 adopts an integrated body design, weighing only 120g, with a small volume, making it easy to install in compact spaces of large equipment; Equipped with four digital display panels and four physical buttons, parameter setting, mode switching, and teaching operations can be completed without connecting to a computer, solving the tedious process of debugging imported sensors relying on dedicated software.
For the calibration needs of long-distance measurement, its teaching function supports 1-point/2-point calibration and area teaching. With an external input time of 0.5~4.5 seconds, it can quickly define the measurement benchmark for long-distance (such as the starting and ending points of large workpieces). Combined with the sampling and holding function, it can easily handle long-distance instantaneous detection in dynamic production lines (such as the positioning of large components on conveyor belts), and the debugging efficiency is 60% higher than that of the Sik OD2 series.
The power supply adopts a DC12-24V wide voltage design (± 10% fluctuation tolerance), with reverse connection protection and overcurrent protection, compatible with industrial general power supply systems; The plug-in M12 8-pin interface and 2-meter oil resistant PVC cable have better installation convenience than the customized interface of the Autesi CD33 series, further reducing the difficulty of on-site deployment.
HC26-195 has successfully replaced imported products in multiple long-distance measurement scenarios:
Manufacturing of large equipmentReplacing the Sik OD2 series for machine tool guide rail flatness detection, the repeated accuracy of 50um at a reference distance of 195mm meets the tolerance requirement of 0.1mm level, and the detection range covers the entire length of the guide rail without the need to move the sensor multiple times, resulting in a 40% increase in efficiency;
Roll processingReplacing the Autesi CD33 series to complete the residual detection of large diaphragm coils, the 99.98mm detection range is suitable for the full cycle of coil materials from full to empty. The automatic brightness adjustment function solves the problem of uneven reflection of thin films at long distances, and the measurement stability is improved by 30% compared to imported products;
Warehousing and LogisticsIn large-scale cargo positioning systems, HC26-195's long-range detection capability and IP67 protection, as well as its ability to withstand warehouse dust environments, have reduced equipment failure rates by 70% after replacing imported sensors.
The HC26-195 laser displacement sensor takes "long-distance precision, environmental tolerance, and local adaptation" as its core, and fills the gaps of imported products in medium and long-distance measurement scenarios through targeted technological innovation. Whether it is replacing the performance degradation of the Sik OD2 series at long distances or breaking through the short distance limitations of the Otes CD33 series, it can provide reliable long-distance measurement support for industrial automation at a higher cost performance ratio.
