Our Core – the hlm Modular Principle
Systematic Variety – flexible, well-conceived, individual
Our modular system is the core of our manufacturing philosophy. Instead of developing each solution from scratch, we combine proven components to create exactly the sensor you need. This saves time, reduces costs – and provides maximum design freedom.
Your advantages at a glance:
❯ Mature, technically proven components
❯ Short delivery times due to standardized modules
❯ Optimal price-performance ratio
❯ Fair prices through modular manufacturing
❯ Individual sensor solutions starting from 1 unit


Our products are created with the utmost care – genuinely handcrafted, directly at our Petershagen location. Our manufacturing has been certified according to DIN EN ISO 9001 by TÜV Nord since 2011.
