ミリ単位の精度の長距離測定用レーザー距離センサー

The laser distance sensors of the LDM71 series 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. For OEM partners we offer this sensor as LDM72 series laser distance sensor module for integration into customer-specific sensor and automation systems.

The compact LDS30 series distance sensors measure distances to natural surfaces of low reflectance with measurement frequencies of 30 kHz. The LDS30 laser distance sensor uses the time-of-flight method and operates with an eye-safe class 1 laser (wavelength 905 nm) to achieve a range of 30 m for surfaces with 10% reflectance. In conjunction with reflective surfaces or special targets this range may be increased to distances of up to 250 meters. The extremely compact, lightweight, and case-hardened chassis makes the LDS30 series laser distance sensor resistant to normal impact and shock associated with industrial applications. The chassis design also make the LDS30 series sensors impervious to dust infiltration and moisture impregnation (IP67 / NEMA 6).

The laser distance sensors of the LDM301 series use a measured time-of-flight principle to measure distances of 300 m for natural surfaces and 3,000 m for reflective surfaces. The fast time-of-flight method with an output frequency of 10 kHz enables object speed measurement. The LDM301 series laser distance sensors is specifically built to measure distances with high precision for surfaces of low reflectance (e. g. asphalt, grass, oxidized steel and aluminum). The distance sensors have proven themselves in the field by measuring moving objects with a reflectance of 6% at distances of 200 meters, especially important for ship docking procedures.

The LDM4x series laser distance sensors measure distances of up to 150 meters, at output rates of up to 50 Hz. The ability to measure with accuracy of a few millimeters within this range is realized by the proven phase comparison method. The red laser beam provides visual confirmation, helps with alignment and targeting. Within a range of 30 m, the LDM4x laser distance sensor is capable of measuring with millimeter precision on natural surfaces. The sensor measures distances without contacting the measured surface, thus eliminating wear and associated errors. Jenoptik’s LDM4x series features a case hardened chassis that is seal from the environment in order to keep dust, water spray, and the weather out of the optical systems. The LDM4x laser distance sensor may be configured with internal heating to increase the operating temperature range to -40 °C … +50 °C.
