Product Overview

The SICK Dx35 laser distance sensor is a high-precision, versatile measurement device designed for accurate distance detection in industrial environments. It offers a wide measuring range from 50 mm to 12,000 mm with performance optimized for different reflection conditions—up to 90% remission factor at longer ranges. The sensor delivers exceptional resolution of 100 µm and maintains high repeatability of ≥0.5 mm, ensuring reliable process data. With multiple output options including current (4 mA to 20 mA), voltage (0 V to 10 V), and digital outputs, the Dx35 adapts to diverse control system requirements. Its IO-Link V1.1 capability enables real-time parameterization, diagnostics, and process data exchange at a transmission rate of 38.4 kbit/s. Ideal for applications requiring precise object detection and dynamic range adjustment, the Dx35 combines robust performance with user-friendly teach-in functions for analog and digital outputs.

Key Features and Technology

The Dx35 leverages a visible red laser light source to provide accurate distance measurements across a broad range. The emitted beam has a typical spot size of 15 mm × 15 mm at a distance of 2 meters, ensuring consistent targeting and minimal interference in industrial settings. The sensor supports multiple switching modes including Distance to Object (DtO), switching window, and object between sensor and background (ObSB), enabling flexible configuration for various detection scenarios. Users can teach-in analog outputs and invert them as needed, along with digital output settings and inversion. The set speed feature allows adjustment from Super Fast to Super Slow, optimizing response time based on application needs. With a response time ranging from 2.5 ms to 96.5 ms (including 2.5 ms / 6.5 ms / 12.5 ms / 24.5 ms / 96.5 ms options), the sensor ensures fast and reliable feedback in dynamic environments.

Technical Characteristics

The SICK Dx35 delivers a measuring range of 50 mm to 12,000 mm under 90% remission factor conditions, while maintaining performance at 50 mm to 5,300 mm for 18% reflection and up to 3,100 mm for 6% remission. Measurement accuracy is typical of ±10 mm. The sensor achieves a resolution of 100 µm and exhibits repeatability of ≥0.5 mm. Response times vary from 2.5 ms to 96.5 ms depending on configuration, with selectable modes at 2.5 ms / 6.5 ms / 12.5 ms / 24.5 ms / 96.5 ms. Switching frequencies are available at 333 Hz, 100 Hz, 50 Hz, 25 Hz, or 6 Hz. Output time ranges from 1 ms to 32 ms (with options of 1 ms/2 ms/4 ms/8 ms/32 ms). The output can be configured as current (4 mA to 20 mA), voltage (0 V to 10 V), or digital, with a maximum output current of ≤100 mA. The sensor features a 12-bit resolution for analog outputs and supports IO-Link V1.1 for process data exchange.

Configuration and Integration

The Dx35 offers flexible integration through its adaptable output options: current (4–20 mA), voltage (0–10 V), or digital output, with a configurable output type via Q2. Digital outputs support teach-in and inversion for tailored logic control. IO-Link V1.1 enables seamless communication with host systems, allowing real-time parameterization, diagnostics, and process data retrieval at 38.4 kbit/s. The sensor supports multiple switching modes—Distance to Object (DtO), switching window, or object between sensor and background (ObSB)—to match specific detection requirements. Users can easily configure and adjust settings via teach-in functions for both analog and digital outputs. With a push-pull output type supporting PNP/NPN configurations and a maximum output current of ≤100 mA, the Dx35 integrates reliably into a wide range of industrial automation systems.

Operating Environment

The SICK Dx35 is designed for reliable operation in standard industrial environments. It operates within ambient temperatures ranging from –25 °C to +70 °C and can function under relative humidity up to 95% non-condensing. The sensor is suitable for use in clean, dry, or moderately dusty conditions but should be protected from direct exposure to moisture or corrosive substances. Its robust construction ensures long-term stability and performance in harsh industrial settings. While not explicitly rated for explosion-proof or intrinsically safe environments, it meets general industrial safety standards. The device is designed for continuous operation under normal process conditions and is suitable for use in both stationary and mobile applications where precise distance measurement is required.

Industrial Applications

The SICK Dx35 laser distance sensor is ideal for a wide range of industrial automation tasks requiring accurate, real-time distance detection. It is commonly used in packaging, material handling, and assembly lines to detect object presence, measure thickness, or verify positioning. The sensor’s wide measuring range and adaptability make it suitable for both close-range and long-distance applications. Its IO-Link capability enables integration into smart factory systems with advanced diagnostics and data logging. Applications include level monitoring, edge detection, product counting, and quality control processes where precise object distance measurement is critical. Whether used in high-speed production or low-motion environments, the Dx35 provides consistent performance across varying reflection conditions and operating speeds, ensuring reliable operation in diverse industrial settings.”}
