r-PA
Product Description
r-PA Series Safety Light Curtain is designed to protect machine operators and plant personnel from hazards associated with moving machinery with fail-safe control reliability. In operation, r-PA extends a collimated “Curtain of Light” in front of hazardous areas. If a worker’s hand interrupts the “light curtain”, a signal is sent to the “stop” circuit of the machine. r-PA is designed with fail-safe circuitry, if any component within the system fails, a stop command is sent to the press, disabling it until the failure is corrected.
