Sick AG

Sick AG was founded in 1946 by Erwin Sick (1909–1988); he had received a license from the then-US-managed local government to operate his engineering firm. The economic breakthrough came in 1952 with the volume production of the accident-prevention light curtain, presented at the International Machine-Tool Trade Fair in Hanover. In 1956, the company moved from Vaterstetten to Waldkirch (Breisgau). Sick AG has a global presence with 63 subsidiaries and participations, as well as numerous sales agencies. According to the company’s own statements, it invests about 12.2% of its sales revenue in research and development in 2024. ==Products==
