A new gerneration of fork sensors has been introduced at the Hannover Fair 2009. These fork sensors are designed as a full modular system. The detecting distance is free adjustable. Different fixed detecting distances are required in various applications. This problem can now be solved with just one adjustable unit (from 5...85 mm or 5...145 mm). The switching sensitivity is permanently controlled through our patented automatic control system, working under harsh conditions like dust, spray, water etc.
