LDM41A is an optoelectronic distance measuring device for industrial applications with an analogue interface 4...20 mA. It works contact-free on the principle of comparative phase measurement (amplitude modulation) and facilitates precisely accurate measurement of distances. It distinguishes itself through high precision as well as high independence from the surface of the measuring object. The red, visible laser beam allows for easy alignment. The sister model LDM42A has been further developed for fast distance measurements on white surfaces.

LDM301A measures distances to targets up to 3000 m away with a precision down to the centimeter. It is able to detect the speed of moving objects with high accuracy. Operated without a reflector, the LDM301A convinces with a range of 300 m on almost each surface. In addition to the large working range, the LDM301A is characterized by very short measuring times down to 0.1 ms. The compact design of the device, the easy set-up and the standard interfaces RS422 or RS232 allow for easy installation and operation. The status of the device can be monitored via LED display during operation. The heating integrated in the device ensures reliable operation at temperatures as low as -40°C. The LDM301A offers the option to add a visor or additional interfaces, such as PROFIBUS DP and SSI.

LDM302A is technically based on the versatile LDM301A. It has, however, especially been optimized for reliable distance measurements on poorly reflecting surfaces. The proven time-of-flight measurement principle combines high resistance against ambient interferences with the safety of laser class 1. The high-energy, but very short laser pulses allow for measurements with centimeter precision and a high repetition rate. The signal processing that has been changed compared against the LDM301A ensures reliable measurements up to 200 m without reflectors with a target reflectivity of only 6%. The sensor can also be used in harsh industrial environments, such as ports or open cast mines due to the integrated heating and the protective housing according to protection class IP 67. The LDM302A offers the option to add visors or additional interfaces such as Profibus DP.

LDS30A laser distance sensor is intended for general distance measurements that require extremely fast data acquisition. It provides up to 30,000 centimeter-precise measuring values per second – up to 30 m without a reflector. With appropriate reflectors the LDS30A reaches objects at distances of up to 250 m. The sensor has been optimized for easy system integration and has a shock-proof and impact-resistant IP 67 housing. Thus, it is most suitable for applications that impose high impact on the sensor, such as harsh industrial environments. Due to the invisible and eye safe laser (905 nm) the LDS30A can also be used in public areas.
