Safety Devices that Support the Reliability of Machinery and Equipment

摘要

Against a backdrop of frequently occurring accidents at factories, railways and the like, interest in the safety of machinery and equipment is increasing. A newly developed short interruption restart relay combines the three functions of instantaneous restart, timed restart and prohibited restart in response to a power failure, and makes possible the safe implementation of the motor restart control. Also, a variety of safety standard-compliant devices such as emergency switches, trip wire switches, safety door switches, light curtains, safety mats, two-hand control stations and safety relay units are provided and help to reduce the risk associated with machinery and equipment.
