ASM Sensors

What ASM Sensors does

ASM Sensors, legally ASM Automation Sensorik Messtechnik GmbH, is a privately held German manufacturer of industrial position and displacement sensors founded in the 1980s by Klaus Manfred Steinich and headquartered in Moosinning near Munich. The company designs and produces non-contact, wear-free magnetic sensors across three families — displacement (POSIWIRE cable extension, POSITAPE tape extension, POSICHRON magnetostrictive including the EasyMount external-mount variant, POSIMAG lin magnetic scale), angle (POSIROT magnetic absolute, POSIMAG rot magnetic incremental, POSIHALL magnetic multiturn, AWS potentiometric), and inclination (POSITILT standard and POSITILT PTK gyro-compensated MEMS) — plus the NMG2 stop-time measuring system for safety compliance under EN ISO 13855. Its technology base spans magnetostrictive time-of-flight, magnetoresistive scale reading, multi-Hall magnetic encoders, and MEMS accelerometers with gyro-fusion firmware, hardened by IP68/IP69 stainless-steel packaging for harsh-environment applications.

The business is run as a family-managed GmbH under managing directors Klaus Manfred Steinich, Dr. Ines J. Steinich, and Rüdiger Köhler, with no disclosed external investors and a US subsidiary, ASM Sensors, Inc., in Elmhurst, IL. ASM generates revenue through direct B2B hardware sales — quote-based industrial pricing with no public list prices — using a regional direct-sales motion from offices in Germany, the USA, France, and Italy, supported by a multi-language website (DE/EN/FR/IT) and topic-specific inquiry forms covering displacement, angle, inclination, measuring equipment, and repair requests. Revenue streams break into industrial position sensors, complete measuring systems, and accessories/spare parts.

ASM serves a diversified industrial customer base across machinery, heavy equipment and lifting, mobile equipment, hydraulic systems, vehicle testing, aerospace research, precision manufacturing, and medical equipment (including CT and mammography patient positioning). Its durable value proposition is magnetic and wear-free measurement that outperforms optical encoders in dirty, icy, vibratory, or washdown conditions, supports long maintenance-free service life, and offers installation-economy features such as external hydraulic-cylinder mounting and dynamic-condition inclination compensation unavailable in competing optical potentiometer or string-pot architectures.
