Overview
The STI MCF4208RE-1 is a compact infrared light curtain receiver from the MicroSafe line, designed to form the detection side of a matched transmitter-receiver safety light curtain system. This 9-inch receiver bar integrates with STI MCF4200 series transmitters to create a protective sensing screen at machine access points. The receiver monitors beam interruption and outputs safety signals to control machine motion, making it essential for OSHA-compliant machine guarding in presses, shears, conveyors, and assembly equipment.
