The SICK DT35-B15251 measures the distance between the sensor and a target without physical contact. It uses time-of-flight technology with visible red laser light, calculating distance from the travel time of emitted and returned light pulses. The sensor can measure up to 12 m on targets with 90% remission, while its 100 µm resolution supports detailed measurement of changing object positions.
In automated machinery, the DT35-B15251 can be used for position monitoring, object distance measurement, material handling, storage and retrieval equipment, conveyor systems, and production-line control. It is suitable where machines need continuous distance information to check component position, monitor movement, control handling equipment, or maintain a defined distance from an object.
The DT35-B15251 uses an ABS/PC plastic housing and PMMA optical window in a compact 32 × 58.67 × 42.7 mm body. IP65 and IP67 enclosure ratings provide protection against dust and water exposure encountered in industrial installations. A 12–30 V DC supply, M12 5-pin connector, and robust construction make the sensor suitable for integration into machinery and automation equipment requiring dependable distance measurement.
