The laser distance sensors LDS70A are designed for measurements of moving targets. The sensor is characterized by a high output frequency of up to 40 kilohertz. Typically, the distance sensor is used to detect objects in industrial automation or for monitoring defined areas in transport and logistics applications. The compact laser distance sensor is offered as a ready-to-use device with industry standard IP67 proof housing. It provides precise measuring values up to 70 m without a reflector. With appropriate reflectors the LDS70A reaches objects at distances of up to 270 m.
