International Standard Attitude toward Ensuring Safety Safety Confirmation System: The machine can be activated only after the safety is ensured. Safety Integrated Design: Safety design is integrated into the machine so that any human errors or machine failure will not cause any accident. System Establishment: A system is established which can operate only when human security is ensured. What is Risk Assessment for safety design of machinery? Risk assessment is a procedure in which the degree of risk is evaluated to exclude risk of a machine and ensure safety when you design or redesign the machine....

About Non-contact Safety Interlock Door Switches Safety Comparison between General Switches and Our Non-contact Safety Interlock Door Switches General Switches (Ex. Mounting on a door) When machine door is open: Switch is OFF → Machine is stopped. (Machine cannot be operated.) When machine door is closed: Switch is ON → Machine is running or can be operated. In addition, machine is stopped if machine door is opened during its operation. ① Safety cannot be ensured in case of unexpected breakdown Contact welding! Overcurrent can cause loss of functions Put magnet on detecting unit Very dangerous...

About Non-contact Safety Interlock Door Switches Certifications Comply with RoHS Directive About ISO 13849-1:2015 Conventionally, safety was designed and evaluated based on deterministic point of view, represented by such electrical parts (non-semiconductors) as switches and relays. However, as machinery/devices are getting more complex and software control is prevailing, such a conventional safety assessment method does not match real environment. Thus, safety design and evaluation have been revised as ISO 13849-1:2015 incorporating the concept of IEC 62061. As a result, in addition to the conventional...
