The SICK DT35-B15551 belongs to the Dx35 Distance Sensor series. It uses HDDM™ high definition distance measurement technology. This sensor measures distances from 50 mm to 12,000 mm on 90% remission targets. Furthermore, it works without a reflector on natural objects. The device suits packaging lines, material handling, and robot positioning. Additionally, its Class 1 eye-safe laser allows use in open work areas.
The DT35-B15551 provides a measuring range of 50 mm to 12,000 mm on 90% remission. On 18% remission, the range reaches 5,300 mm. On 6% remission, it reaches 3,100 mm. It uses a visible red laser diode at 658 nm. The laser class is Class 1 eye-safe per IEC 60825-1:2014. Average optical power stays below 1 mW. Response time depends on the speed setting. Super Fast mode delivers 4.5 ms, while Super Slow mode reaches 192.5 ms. Repeatability ranges from 0.5 mm to 5 mm. Measurement accuracy is typically ± 10 mm. Moreover, HDDM™ technology offers high immunity to ambient light and surface colors.
The sensor includes one digital output Q1. It works as push-pull PNP or NPN. IO-Link V1.1 communication is also supported. A shared configurable output Q2 offers three modes. It can work as analog current from 4 mA to 20 mA with a load up to 450 Ω. It can also provide analog voltage from 0 V to 10 V with a load of at least 50 kΩ. Alternatively, Q2 works as a digital push-pull output. A multifunctional input is included. The supply voltage ranges from DC 12 V to 30 V. Reverse-polarity protection is built in. Power consumption is ≤ 1.7 W at +20 °C without load. For instance, electrical connection uses a male M12 5-pin connector.
The operating temperature range is -30 °C to +55 °C at Uv ≤ 24 V. Storage temperature ranges from -40 °C to +75 °C. The enclosure protection rating is IP65 per EN 60529. Physical dimensions are 32 mm x 58.6 mm x 42.7 mm. The housing uses plastic ABS/PC with an acrylic glass PMMA optical window. The device weighs approximately 65 g. Besides, on-board teach-in pushbuttons and status LEDs speed up commissioning.
First, mount the sensor on a stable bracket facing the target surface. Next, connect the M12 5-pin cable for power and output signals. Then, select the speed setting that matches your cycle time needs. Meanwhile, verify the supply voltage stays within DC 12 V to 30 V. After that, configure Q2 as analog current, analog voltage, or digital output. If IO-Link is active, keep the supply voltage above 18 V. Use the teach-in pushbuttons for quick setup. Finally, verify the readings with the status LEDs.
