Pepperl+Fuchs ML4.2 Series Subminiature Photoelectric Sensors have faster response times, multi-beam redundant detection, independent outputs and zero deadband sensing. The newest ML4.2 high-speed models offer 250 µs response time, half the time of the standard ML4.2 models. ML4.2 dual sensor redundant detection models have dual light beams from two emitter LEDs that reflect light to two receivers. Compared with single beam sensing, the redundant light beam enables more reliable sensing of transparent or glossy objects that are foil or plastic-wrapped.
