The SICK DT500-A311 belongs to the Dx500 Short Range series. It uses pulsed optical laser time-of-flight measurement technology. This sensor measures distances from 0.2 m to 7 m on most surfaces. Furthermore, it works without a reflector on dark or uncooperative materials. The device suits hot slabs, metal coils, coal, and paper rolls. Additionally, its heavy-duty aluminum housing resists severe vibration and impact.
The DT500-A311 provides a measuring range of 0.2 m to 7 m on 90% white remission. On 6% black remission, the range is 0.8 m to 7 m. It uses a visible red laser diode at 650 nm. The laser class is Class 2 per IEC 60825-1:2014. Average optical power stays below 1 mW. Response time is 150 ms in fast short-range mode. Repeatability ranges from 3 mm to 5 mm. Measurement accuracy is typically ± 3 mm to ± 10 mm. Moreover, high optical output power ensures reliable measurement on dark surfaces.
The sensor includes one analog current output from 0 mA to 20 mA. It supports a load of up to 500 Ω. A serial RS-422 interface is also available. One PNP multifunctional input is included for external triggering. The supply voltage ranges from DC 10 V to 30 V. Reverse-polarity protection is built in. Power consumption is ≤ 3.5 W to 4 W without load. For instance, electrical connection uses a male M12 5-pin connector. Therefore, wiring stays simple and fast.
The operating temperature range is -10 °C to +45 °C. Storage temperature ranges from -25 °C to +75 °C. The enclosure protection rating is IP65 per EN 60529. Physical dimensions are 69 mm x 50 mm x 153 mm. The housing uses heavy-duty aluminum die-cast material. The device weighs approximately 1,000 g. Besides, a front panel display and keypad allow direct on-site setup.
First, mount the sensor on a stable bracket near the target area. Next, connect the M12 5-pin cable for power and analog output. Then, wire the RS-422 lines if serial communication is needed. Meanwhile, verify the supply voltage stays within DC 10 V to 30 V. After that, use the front panel keypad to set the measuring range. The display shows live readings for quick verification. Finally, test the sensor on the actual target material. Adjust the analog output scaling for your controller.
