Sick DS35-B15221 Mid-range Distance Sensor
The Sick DS35-B15221 is a laser-based distance sensor designed for industrial automation and positioning tasks. It measures from 50 mm to 12,000 mm on targets with 90 % remission and down to 3,100 mm at 6 % remission. A resolution of 0.1 mm and typical accuracy of ± 10 mm suit precise object detection and distance monitoring applications.
Supply voltage 12 V to 30 V DC
The sensor operates on a DC supply between 12 V and 30 V with a maximum ripple of 5 Vpp and consumes 1.7 W. Initialization completes in 500 ms followed by a 20-minute warm-up for full stability. The red laser is rated Class 2 per IEC 60825-1:2014 and offers a typical service life of 100,000 hours at 25 °C.
Response time 2.5 ms to 96.5 ms
Under sustained operation the sensor provides configurable response times of 2.5 ms, 6.5 ms, 12.5 ms, 24.5 ms or 96.5 ms paired with matching switching frequencies from 333 Hz down to 6 Hz. Output time scales from 1 ms to 32 ms. Switching modes include Distance to Object, switching window and object between sensor and background, all teachable via the multifunctional input.

Questions about this item
How do I mount the DS35-B15221 and wire the male connector correctly?
Mount the ABS/PC and PMMA housing securely, then connect the male connector to a 12 V to 30 V DC supply with no more than 5 Vpp ripple; allow 500 ms initialisation and 20 min warm-up before relying on measurements.
When will the laser need replacement and what triggers it?
The red Class 2 laser is rated for 100,000 hours at 25 °C; plan replacement when output degrades after this period or if the multifunction input is used to disable the laser frequently.
At what distance does repeatability exceed half a millimetre on low-reflectance targets?
Repeatability is specified as ±0.5 mm up to 3,100 mm on 6 % remission surfaces; beyond that range the spec no longer guarantees the same repeatability.
