Product Introduction

The SICK DT35-B15551S04 is a compact time-of-flight sensor from the Dx35 series. It measures natural objects across a wide range without contact. Moreover, the device combines a visible red laser with advanced signal processing. This design ensures stable results in many industrial environments.

Technical Specifications

The DT35-B15551S04 covers a measuring range of 50 mm to 12,000 mm at 90% remission. For 18% reflection factor, the range reaches 50 mm to 5,300 mm. Furthermore, at 6% remission factor, it spans 50 mm to 3,100 mm. The resolution is 100 µm, while repeatability is ≥ 0.5 mm. Measurement accuracy is typically ± 10 mm.

The response time varies from 4.5 ms to 192.5 ms. Available steps include 4.5 ms, 12.5 ms, 24.5 ms, 48.5 ms, and 192.5 ms. Switching frequency values are 166 Hz, 50 Hz, 25 Hz, 12 Hz, and 3 Hz. Output time ranges from 2 ms to 64 ms, with selectable values of 2 ms, 4 ms, 8 ms, 16 ms, and 64 ms.

The light source is a red laser, class 1 according to IEC 60825-1:2014. The typical light spot size is 15 mm x 15 mm at 2 m. Average laser service life reaches 100,000 hours at 25 °C. Additionally, the sensor offers a speed setting from Super Fast to Super Slow.

Outputs and Interfaces

The DT35-B15551S04 provides one analog output and up to two digital outputs. Specifically, output Q2 is adaptable as a current output, voltage output, or digital output. The analog current range is 4 mA to 20 mA with a load up to 450 Ω. The voltage range is 0 V to 10 V with a load of at least 50,000 Ω. Analog resolution is 12 bit, and hysteresis spans 0 mm to 11,950 mm.

Digital outputs use a push-pull PNP/NPN type. Maximum output current is ≤ 100 mA. Switching modes include Distance to Object, switching window, and object between sensor and background. Besides, the multifunctional input supports laser off, external teach, or deactivation.

The sensor includes IO-Link V1.1 with COM2 at 38.4 kBaud. This interface enables process data, parameterization, diagnosis, and data storage.

Mechanical and Environmental Parameters

The housing measures 32 mm x 58.67 mm x 42.7 mm. It uses plastic ABS/PC, while the window is PMMA. The weight is 65 g. The enclosure rating is IP65 and IP67. Protection class is III.

The supply voltage ranges from DC 12 V to 30 V. Power consumption is ≤ 1.7 W, and ripple is ≤ 5 Vpp. Initialization time is ≤ 500 ms, and warm-up time is ≤ 20 min.

Operating ambient temperature ranges from –30 °C to +55 °C with Uv ≤ 24 V. Storage temperature ranges from –40 °C to +75 °C. Maximum relative humidity is ≤ 95%, non-condensing. The sensor meets EN 60068-2-6, EN 60068-2-64 for vibration and EN 60068-2-27 for shock. EMC standards include EN 61000-6-2, EN 61000-6-3, and EN 61000-6-4.

Installation Guide

First, mount the DT35-B15551S04 using the appropriate bracket for your application. Next, connect the male connector to a stable power supply within 12 V to 30 V DC. Then, align the sensor toward the target object. The visible red laser helps with rough alignment.

After wiring, configure the output mode through IO-Link or teach-in. For instance, set Q2 as current, voltage, or digital output. Meanwhile, adjust response time and switching frequency to match your control cycle. Finally, verify the measured distance and fine-tune the switching window if needed.
