About DINA Elektronik
DINA Elektronik GmbH develops and manufactures safety switching devices for machines and production systems. The portfolio includes sensorless monitors for standstill, speed, direction of rotation and phase monitoring, emergency-stop and time relays, as well as safe compact controllers and the modular safe miniature controller SAFELINE VARIO, which can monitor up to 30 axes. The modules operate sensorlessly by evaluating the electromotive force (EMF) and require no external sensors; the housings are made of unreinforced polyamide (PA), and the relay contacts use the contact materials AgNi or AgSnO2. The products are certified for Performance Level e (EN ISO 13849-1) and SIL 3 (IEC 61508). Areas of application include machine tools, woodworking, the automotive industry and intralogistics; customers include machine manufacturers such as bavius technologie, Carl Cloos Schweißtechnik, STIWA, DeLaval, WEINIG, DIOSNA and Continental. The company was founded in 1987 by Dirar Najib in Wolfschlugen, where development and production are located at the headquarters; a further site is located in Berlin. All production takes place in Germany, and sales are handled through a worldwide distributor network.
