When did we start
STS Electronics Ltd. started its activity in 1990. in the city of Gabrovo - Bulgarian Manchester. The first sensors developed and marketed by just a few people are the Inductive series. From this point onwards, the company expands its product portfolio by adding fiber optic, ultrasonic, magnetic and capacitive sensors to the family. The development and production of peripheral electronic devices such as timers, counters, power units and others have been developed to complement the automation process of our customers. With only three people at the beginning, at present 40 graduate engineers are now part of the company's team. The organization of the company consists of 3 production departments specialized in specific areas of sensors, warehouse, marketing and sales, constructive and mechanical departments.
