Page 5: Introduction
SAFETINEX SAFETY SYSTEMS The Safetinex product lines produced by Contrinex offer high quality safeguarding solutions for both personnel and machinery. Our special- ists in sensor technology have developed high-performance electro- sensitive protective equipment. -
Page 6: Safeguarding Function
Point of operation: detection of hands entering the defined hazard- ous area. The protective equipment immediately stops the machine or renders it harmless. The Safetinex YBB range is best suited for this type of application. In both cases, the primary function of the protective device is to stop the machine before the hazardous point is reached and to prevent un- intentional machine start-up or restart. -
