The IFM LMT102 is a capacitive point level sensor with a 38 mm probe designed for reliable monitoring of liquids, viscous media, and powders. It uses a G1/2 sealing-cone process connection and a robust stainless-steel housing. Two programmable digital outputs provide flexible switching functions, while IO-Link supports parameterisation, diagnostics, and process-data communication. The sensor is factory preset for water-based media and supports medium temperatures up to 100 °C, with short-time operation up to 150 °C. IP68 and IP69K protection make the LMT102 suitable for demanding process and hygienic installations.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The LMT102 uses capacitive technology to detect the presence of process media at a defined level. Its 38 mm probe provides greater insertion depth than the compact LMT100. The sensor can detect liquids, viscous media, and powders within suitable application conditions. Factory configuration for water-based media simplifies initial installation. IO-Link allows the sensing behaviour to be adjusted for different media when required.
Two digital outputs provide configurable level switching signals for automation equipment. The outputs can be configured as normally open or normally closed. IO-Link 1.1 provides digital access to process data, identification, and device parameters. The minimum IO-Link process cycle time is 2.3 ms. This makes the LMT102 suitable for integration into modern PLC and industrial networking systems.
The LMT102 uses stainless steel 316L, PEEK, PEI, and FKM materials. Its wetted components include a PEEK sensing surface with Ra <0.8 µm / Rz 4 µm surface characteristics. The sensor supports tank pressures from -1 to 40 bar. IP68 and IP69K protection provide strong resistance against water ingress and intensive cleaning. Gold-plated M12 contacts improve connection reliability in industrial installations.

The LMT102 should be mounted using a suitable G1/2 sealing-cone process connection. The probe should be positioned at the required level inside the vessel or process line. Correct tightening and sealing are important for maintaining process integrity. IO-Link can be used during commissioning to verify device parameters and switching behaviour. Routine inspection should focus on the process connection and sensing tip.
The LMT102 is factory preset for hydrous media but can also be configured for other suitable media. This provides flexibility when the same sensor platform is used across different process conditions. The capacitive principle enables detection of liquids, viscous substances, and powders. IO-Link makes sensitivity and device configuration easier to manage. This reduces commissioning effort when application requirements change.
