Founded in 1987, STEM S.r.l. began its production activity by building magnetic proximity sensors and magnetic units. Over the years, the range of products has expanded with the introduction of level switches for industrial applications, sensors and control units for lifts and systems for machine safety designed to integrate sensors and coded magnetic units capable of transmitting signals to special safety control units.

The use of new and increasingly advanced equipment has led to a constant increase in production capacity and ever greater control of all the production steps – critically important to guarantee the highest product quality.

STEM product quality is guaranteed by the achievement of the ISO 9001:2015 system certification (First quality certificate issued by DNV in 1997) and by the product approvals granted by TUV, IMQ, UL.

STEM’s factories, which have grown in size over the years, include an R&D laboratory for fast development of new products by using sophisticated design tools and other equipment to perform reliability, durability and safety tests. The workshops meet all the requirements of the applicable European Community directives.

STEM s.r.l.’s target market mainly consists of national and foreign companies operating both in the industrial sector and the lift manufacturing industry. STEM product export figures have reached a record share of 55% of the turnover with more than 70 countries currently served around the world.
Today, the company can offer to its customers a wide range of products capable of meeting a huge variety of needs and is able to come up with customised solutions, from product design all the way to industrialisation through quick prototyping with 3D printers entirely managed internally.

STEM products are built according to the needs of each individual customer and may require such a high degree of customisation to be easily definable tailor-made products. “STEM, tailor made sensors”
