- 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.
- Positioning of vessels in docking support systems
- Process monitoring in steel and rolling mills
- Monitoring of conveying systems
- Position control in mining
