Industrial MCF47-20-600-R3 Light Curtain Receiver

STI MCF47-20-600-R3 is a receiver module in STI’s MC4700-series safety light-curtain family. Designed to work with a matching transmitter, this infrared beam-based system provides presence-sensing protection for hazard zones by feeding a safety output when the beam is uninterrupted. The MCF4700-series devices are used in automation environments such as mechanical presses, robotic work cells, injection molding, and automated assembly lines, where personnel protection is required around moving machinery. The model carries the 70186-1008 catalog/reference number and is part of the two-output safety configuration typical of MC4700 systems, with quick-disconnect cabling linking transmitter, receiver, and controller. The MC4700/MCF4700 family leverages a microprocessor-based design and can be integrated with a wide range of STI controllers (including LCM-series) and optional RM modules to adapt outputs for safety relay logic. In practice, this receiver provides the protection functions needed to stop or control machinery when a guarded area is breached, helping to meet typical safety standards for industrial equipment.
