The IFM LMC100 is a capacitive point level sensor designed for reliable level monitoring in industrial applications. It detects water-based and hydrous media while providing fast and stable switching performance. The sensor features two programmable digital outputs with IO-Link communication for convenient parameterisation and diagnostics. Its stainless-steel housing and PEEK sensing tip provide excellent durability in demanding process environments. With IP68 and IP69K protection, the LMC100 is suitable for robust tank and vessel level monitoring applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The LMC100 uses capacitive measuring technology to detect the presence or absence of liquids at a defined level. Its factory setting is optimised for water and hydrous media. The sensor provides two digital outputs that can be configured according to the required switching function. Deposit suppression helps maintain reliable switching performance even when residue accumulates around the sensing area. This makes the LMC100 suitable for overflow prevention, dry-run protection, and level monitoring.
The integrated IO-Link interface provides convenient access to sensor parameters and diagnostic information. Communication operates through COM2 at 38.4 kBaud using IO-Link revision 1.1. The sensor supports both standard I/O operation and IO-Link communication. Process data can be exchanged digitally with compatible automation controllers. This simplifies commissioning, parameter adjustment, diagnostics, and sensor replacement.
The LMC100 uses a stainless-steel housing with a PEEK measuring tip for demanding industrial environments. Its G1/2 sealing-cone process connection allows secure installation into suitable process fittings. The sensor is rated IP68 and IP69K for protection against water ingress and intensive cleaning conditions. The operating temperature range supports a broad range of industrial installations. Gold-plated M12 contacts provide a reliable electrical connection.

The LMC100 should be installed using a compatible G1/2 process connection and appropriate sealing arrangement. The sensing tip should be positioned at the required switching level inside the vessel. Correct installation helps maintain reliable detection and minimises unwanted switching. IO-Link can be used to configure operating parameters and verify sensor status. Periodic inspection of the process connection and sensing tip is recommended for demanding applications.
The two digital outputs allow the LMC100 to provide flexible switching information to a control system. IO-Link additionally enables digital parameterisation and process data communication. The sensor can therefore be integrated into PLC-based automation architectures. Its fast response supports timely level-related control actions. This makes it useful for automated filling, draining, and protection systems.
